Homeothermic, or warm-blooded, animals have several game-changing advantages compared to ectothermic, or cold-blooded creatures. Yet in the real world of Nature, nothing is free, and a price must be paid for these advantages. In order to supply all cells with oxygen and fuel, warm-blooded animals require an enormous blood supply and an efficient circulatory system with a 4-chambered heart at the center of it all. In this session, participants will work with research-generated data to build a mathematical model that allows them to estimate their own blood volumes. In addition, we will look at metabolic data comparing warm and cold-blooded animals, and the oxygen requirements of each. Finally, we will evaluate the food input requirements of warm-blooded animals in cold environments compared to warm environments.

TAKEAWAYS:
Being "warm-blooded" brings both good news and bad news for an animal. In this session, attendees will calculate their blood volume, why a 4-chambered heart is needed to move all that blood around, and how the circulatory system is the key to unlock all of these physiological phenomena!

Ask participants to discuss strategies they use to evaluate information online. Briefly share research on how both middle school students and adults often employ faulty strategies. Share research-informed best practices for evaluating information and how it informs our assessment framework for looking at any type of media for relevancy, bias, and credibility. For credibility, we elaborate further on assessing evidence and authority and employing the strategy of lateral reading. Participants engage in a sample article or video and employ evaluation strategies together in small groups. Come back as a whole group and participants share what they found. Share examples of student work. Share instructional strategies to support where we find students can struggle with this skill, provide sample activities, and other supporting resources.

TAKEAWAYS:
Teachers will be provided with a framework and resources to help students engage in arguably the most important skill needed for them to continue to develop their scientific literacy outside of and after school -- to critically evaluate information for themselves and for a functioning democracy.

Science is often portrayed as conducted in a simple linear way (i.e., the scientific method). But this is rarely true in actual scientific practice. Instead of a step-by-step series of actions, science is conducted more cyclically, with scientists working back and forth between pursuing exploration and discovery, assessing benefits and outcomes, and developing analysis and feedback. At the core of this process is evidence, against which ideas in science are constantly tested. Evidence is what drives all scientific understanding. By examining environmental DNA (eDNA) collected from areas where recent Bigfoot sightings have occurred, participants can provide students with a logical and rational way scientists can use evidence to dispel the pseudoscience of cryptozoology. Upon completing this activity, attendees can apply their new knowledge to how eDNA is currently used to identify viruses and diseases in wastewater. Resources: https://ncse.ngo/supporting-teachers/classroom-resources

TAKEAWAYS:
Participants will explore and appreciate the importance of evidence to the scientific process by taking a deep dive into an NGSS storyline sequence developed to help students understand that science must be substantiated by multiple lines of evidence to be accepted by the scientific community.

This lesson focuses on radio astronomy data collected with a $50 student-built telescope. The telescope is not needed to do the lesson. Students collect information on the locations of neutral hydrogen. Easy to do and a primary focus of radio astronomy. The data collected can be used in the classroom to teach lessons on the Doppler Effect, Wave behavior, galactic velocity curves, and effects of gravity as well as other science topics. Many physics concepts can be taught in a highly engaging way by studying the concepts found in astronomy. Doppler effect, rotational motion, wave behavior, the EM spectrum are examples. The challenges to doing such lessons is the high cost of the telescopes and the challenges of collecting astronomy data during daylight hours. Plans for building and operating the radio telescope will be provided. Lesson plans for teaching the Doppler Effect via Red Shift/Blue Shift and for teaching how to work with galactic velocity curves will be included.

TAKEAWAYS:
Radio astronomy is done during class time as radio wave detection is not affected by daylight. Students will learn about the unique nature of galactic rotational behavior as compared to circular motion and planetary motion under Kepler’s Laws.

The more senses we use when learning something, the better we are able to remember it, so in this session teachers will learn how to incorporate movement into their classes. Here are the activities we will do: 1) Modeling an action potential. The graph of an action potential looks a lot like a wave and so to help students remember this, we say the stages of the graph while we make a wave with our bodies (like in a stadium). Then students need to describe what is happening at the cellular level while their bodies are moving. 2) Modeling translation. Participants will be given supplies to take on the role of tRNAs, with anticodons and amino acids, and then show how they enter the ribosome through the A, P and E sites to undergo translation. 3) If time permits, we can also model a signal transduction pathway or DNA replication. 4) The last 15 minutes will be for groups to come up with one way they can incorporate movement and present this to the group.

TAKEAWAYS:
Learn how to get your students up and moving as they use their bodies to act out cellular processes.

Students and educators must remain connected to, and motivated by, the elements of their world that not only spark curiosity and generate wonder but are real. Students care deeply about the environment, climate change, food insecurity, and sustainability. A sustainable and resilient future will only be achieved if we begin to make sense of these challenges in smaller, coherent investigations; starting in our science classrooms. An enormous piece of the sustainability puzzle lies within sustainable food systems. Food production and agriculture provide limitless opportunities for students to explore phenomena among the interactions of living things and the earth’s systems. Further, the practice of agriculture, since its origins, has been a continuous series of design challenges to cultivate nature for the needs of humans. This presentation provides a lens through which students and educators can find opportunities to spark inquiry and solve real-world problems.

TAKEAWAYS:
Educators will see successful examples of authentic phenomena and problems found within food and agricultural systems that are relevant to all students. We will demonstrate how all three dimensions of NGSS are used to make sense of these real-world phenomena.

Working in teams, students take a short analog message and convert it to binary code for cell phone transmission. Students then send those zero’s and one over a carrier wave using a form of amplitude modulation to another team. At the other end the message is decoded and rewritten in analog form. which message was first? How close was it? A discussion of challenges the students’ faced in acting like a DSP (digital signal processor) lets student see some of the challenges of the original binary code and how subsequent forms of coding came about to address some of those challenges. Students discover the binary code they used was Morse code. Students then code and send a different message using the original 5-digit computer code. After racing to send their messages, students are guided through a follow-up discussion on the pros and cons of the new (Baudot) computer code used.

TAKEAWAYS:
Students will understand some of the challenges faced in digital signal processing as sending digital information evolved by completing a lab activity where they will code and decode messages into a digital format for transmission and receiving, similar to how cell phones work.

Finding causes, treatments, and cures for diseases is “STEM on the front-lines.” Without all four components of the STEM model firmly set in place, any serious medical research is destined to fail. Sanford Research in Sioux Falls, SD has formed an “all-star research team” that is committed to finding a cure for Type 1 Diabetes (T1D) and Breast Cancer. In this session, we will highlight the progress that is being made in solving the T1D and Breast Cancer puzzles. Using interactive virtual activities, participants will develop an understanding of the difference between a body that is functioning normally and one that has developed T1D or Breast Cancer. We will wrap up the session with a discussion of the paths that Sanford Research is taking in their quest to help cure the disease. All discussion of human anatomy and physiology will be at a gentle introductory level.

TAKEAWAYS:
Using real case studies, attendees will follow the journeys of a breast cancer survivor and a teenage Type I Diabetic, from diagnosis through treatment.

While not always the case, the experiences that students have had in middle school with genetics can be limited to plug and chug Punnett squares investigating traits in aliens, SpongeBob, and dragons. In an effort to help students see how patterns of inheritance and gene expression can be more nuanced than that and to connect to a real world example, I created a Genetic Counselor project for the 9th graders at The Lawrenceville School (Lawrenceville, NJ). In this session, participants will have the opportunity to work through aspects of the project, specifically creating the pedigree and working with primary literature and analyzing data. This project is great because it includes representation of people of different backgrounds and identities, is based in the real world, introduces students to a career path, and teaches about primary literature. Please see the project launch pad here: https://tinyurl.com/GCPNSTA --Thanks!

TAKEAWAYS:
Work through the genetic counselor project from a patient background, solving a pedigree, learning how to use NCBI, and interpreting primary literature. You will take home the student directions, exemplar projects, list of relevant primary literature articles, and teacher key.

Since the beginning of the COVID pandemic, teachers have had to restructure how they teach. When schools closed, teachers were given multiple options and had to pick one. Many schools chose the Google Classroom option as it was the easiest for some schools to set up, but didn't allow for inclusivity with every student both in and out of the room. Using examples from my own Chemistry and fully virtual Applied Digital Skills classes, I will show how Microsoft Teams can give both the teachers and students a hub for all their presentations, notes, assignments, and even assessments. It allows teachers the ability to grade assignments and for students and parents to see those grades within the platform. It also allows for teachers to keep track of students' mental health and insights that can be shared with parents or councilors about students' habits on their computer. This may not be a science specific topic, but it works so well for managing a science classroom.

TAKEAWAYS:
Attendees will know how to use Microsoft Teams to host virtual lessons, create postings students can read and interact with, create and grade assignments, and how to check in with the emotional needs of students.

Understanding the nature and process of science is critical to scientific literacy. When students engage in the practices of science, they are more likely to integrate science as part of their own identities (Gee, 2007). To do this successfully, students must reflect on what they are doing and why, along with comparing their strategies to those of professional scientists (NRC, 2011). In this session, participants will examine their own conceptions of the nature and process of science, make connections to pedagogical frameworks (NGSS SEPs & CCCs), engage as students to use the Flowchart Mapping tool from the Understanding Science project to trace their approach to figuring out a biological phenomenon about why blue whales are so big, compare their process to that of the scientists investigating the phenomenon, and reflect on how they might use this tool and strategy in their own classrooms with other phenomena or lessons.

TAKEAWAYS:
Participants will learn how to use the Science Flowchart interactive journaling tool to illuminate the dynamic nature and process of science, and how to apply the tool to any phenomenon or lesson in their classroom.

Although there is no shortage of potential phenomena for teaching about the process of evolution, using human evolution is a sure way to make the topic relevant and engaging for all students. It is also an excellent way to address some of the most common student misconceptions surrounding the subject, such as “humans evolved from monkeys,” “if humans evolved from apes, why are there still apes?” and “humans are the pinnacle of the tree of life and therefore no longer evolving like other organisms.” By examining a wide range of evidence, including different potential variations of hominid skulls (physical replicas, cards, or 3D digital models), geographic data, artifacts, and climate trends, students will be able to piece together a model of hominid phylogeny and learn about the changes in anatomy, behavior, and distribution that led to our unique human features. Resources: https://ncse.ngo/supporting-teachers/classroom-resources

TAKEAWAYS:
Participants will explore a range of paleoanthropology evidence to confidently guide students through one of the most engaging evolutionary phenomena – human evolution. Learn about extinct hominid groups and how they are connected to human origins through features, behaviors, and relationships.

I will be presenting a short storyline I created. It incorporates the phenomena that whey protein comes from cows. Whey protein is a "buzz" item lately with the workout craze, workout supplements, etc. Throughout the storyline, students will make connections with proteins, dairy (cows), other macromolecules, and homeostasis. Students will learn how to make cheese and that the by-product is whey protein. They will test various workout supplements and health foods for macromolecules. They will learn about homeostasis: positive and negative feedback loops through working out (heart rate and breathing rates). Lastly, they will complete a project where they have to figure out which proteins are best for the human body and then create a product and it's packaging (i.e. protein bar, shake, drink, etc). Teachers will get to experience some of the labs and receive all of the paper resources to take back and implement the storyline or parts of the storyline in their classroom.

TAKEAWAYS:
If you have never used storylines, this is a great short one you can try in your class. You will leave this session with beneficial resources you can take back and use in your Biology classroom.

The presenters will show a brief overview of standards based grading and mastery learning. They will also share how much it has spread in recent years. There are many aspects of SBG that can be challenging for secondary science teachers, we will name those and give tangible ideas to support alignment to the Next Generation Science Standards. This will be done from inspecting classroom examples, examples from research, and sharing personal accounts as a whole group. A large complication with SBG in secondary science classrooms is creating assessments that align with both SBG practices as well as NGSS performance expectations and three dimensionality. The melding of these concepts is new, challenging, and not being done in current research.

TAKEAWAYS:
Standards-based grading is becoming more prevalent in schools; it is important to see tangible and realistic ways to implement these practices while still aligned to the NGSS. We will share best practices in the conjoining of these two concepts as well as ways to support student growth.

SPEAKERS:

I will take participants through my process of crafting sets of formative multiple choice questions that each use 2 of the 3 dimensions of NGSS, so that all dimensions are addressed. I will also show my process for refining free response questions to get the exact responses I am looking for and that allow for an ease of grading and seeing students’ understanding. I will provide examples from my own classroom & direct them to where they can find more examples from various storylines. As an iHub Chemistry writer, I learned to write 3-D multiple choice formative questions. An assessment graduate course taught me how to write quality distractors to see limits of student understanding and get useful feedback data. I merge these 2 in my own classroom to create assessments to get to what my students know. I will share my learning from these trainings and more to set teachers on the path to quality 3-D classroom assessments.

TAKEAWAYS:
Learn to craft three-dimensional assessments, multiple choice, and free response. Using quality distractors in multiple choice formatives allows you to pinpoint student misconceptions. Free response questions direct students to the specific response you want so that grading goes quicker.

Food is a basic necessity of life, yet in the United States there are over 6,500 food deserts affecting 19 million people. Food deserts are geographic areas that lack access to affordable, healthy food options. During this session, participants will engage in conversations for how to address this inequity with students as they engineer food producing hydroponic systems. The Hydroponics storyline is the third in a series being developed by a group of 25+ educators from the midwest for science and agriculture teachers that engage students in developing explanations for agricultural phenomena and solving real-world problems. Students utilize the three dimensions of NGSS in each of the storylines as they learn about food systems, or the production, processing, distribution, and consumption of food products and interactions with the natural environment. Specific emphasis is placed on developing skills related to the Scientific & Engineering Practices and building Crosscutting Concepts.

TAKEAWAYS:
Participants will learn about a new storyline on hydroponics that explores food deserts which are geographic areas that lack access to affordable, healthy food options. Attendees will discuss one option for addressing this inequity with students as they engineer food-producing hydroponic systems.

Connect the human impact of trash pollution to engineering design. Get your students thinking critically and creatively as they collaborate in real-world problem-solving. The global real-world issue of human-generated trash polluting local bodies of water is the main focus of this hands-on session. Using our partnership with the Howard County Conservancy, our students learn about their local watersheds and contribute to a Watershed Report Card. Students see how trash that is often found on our local schoolyards can affect our watershed, and they design a working model for trash removal in a local tributary. Basic coding will be used to design programs that will control sensors and motors through a microcontroller, thus removing the trash from the water source. The model will utilize solar and water power to move the trash into a separate receptacle. Various sensors will also be used to monitor water levels and determine the outcome of the program.

TAKEAWAYS:
1. Connecting the human impact of single-use plastics and their effect on aquatic ecosystems; 2. Exposing students to basic coding and engineering design in an NGSS-focused content classroom; and 3. Developing a project that enhances STEM skills in students such as collaboration, curiosity, and creativity.

Participants will use web-based image and data analysis software and real data sets to compare the Cartwheel Galaxy in optical and X-ray bands to determine the sources of the ultra and hyperluminous X-rays in the galaxy. This investigation can be done on smart phones, laptops, and tablets with an internet connection. The unusual shape of the Cartwheel Galaxy is most probably the result of a collision with one of the smaller nearby galaxies several hundred years ago. The collision produced compression waves within the galaxy which triggered bursts of massive star formation. Participants will use the location of the U/HLXs on the x-ray image and optical image, as well as information about expansion rates and the life cycles of stars to determine what these objects might be. This is a great introduction to the software that astrophysicists use. Participants will also learn about the possibilities for other kinds of investigations and research with the software and the thousands of available data sets.

TAKEAWAYS:
Astrophysicists use light in all bands of the electromagnetic spectrum to determine the nature of an object. Web-based software will be used; the same tools used by scientists. This software can be used by students to do their own investigations in astronomy with real data sets.

Schoobio (Schoolyard Biocultural Diversity Community) is a free, transdisciplinary, project-based, student-led curriculum. It focuses on active learning culminating in youth developing a sense of place, envisioning their ideal bioculturally diverse school grounds, and advocating for their plan with school and community leaders. The curriculum’s goal is increased numbers of school grounds reflecting the biodiversity and cultural traditions of the students. These “habitat islands” will help species connect with larger habitat areas, forming green belts within cities and throughout the countryside. They will also make school grounds more reflective of the cultures and traditions of their students and communities. In this workshop, teachers will learn about the progressive activities of Schoobio, experiencing science, culture, and literary aspects: mapping school grounds, engaging in a nature-culture exercise, and envisioning their ideal ecological, culturally diverse school grounds.

This presentation will involve a Google Slide show detailing why some of our beloved labs do not meet the NGSS standards and how we can adjust these labs through phenomena, critical thinking questions, CER, and rubrics to meet those standards. Furthermore, this presentation's primary purpose is to highlight why we struggle with "students today." It is a fact that students have changed; we expect students to change. It's the fact that we as educators have not adapted to the students that are in front of us today. They have changed but have we, as educators? Have our lessons and lab experiences changed with them? This presentation will show how to adapt and adjust old lab experiences (biology, chemistry, environmental science, and physics) to meet the NGSS standards and why newer phenomena-based lessons differ from old recipe labs. If time permits, teachers will work on a lab they want to update.

TAKEAWAYS:
The main takeaway from this presentation will be how we incorporate rubrics, critical thinking questions, and phenomena into our lab experiences to meet the students & standards of today—cultivating an engaging and collaborative experience for the students.

Stars form in giant molecular clouds of gas and dust in massive star formation complexes, and depending on their initial mass, usually follow a sequence that ends in their destruction in catastrophic collapses and explosions. The process of stellar evolution provides the energy which drives the universe, and thereby determines its future. During the last stages of evolution, nucleosynthesis creates the elements which will enrich the next generation of protostars and planets. formation of stars also sets the stage for possible exoplanets forming within the debris disks of young protostars as hydrogen begins to fuse in their cores. This basic sequencing activity is one of a series of activities designed to show how scientists view, study, and examine the process of stellar evolution. The card sets have descriptions and links and can be used as a pretest or a posttest, either individually or as a group. Multiple answers are acceptable. A scoring rubric is included.

TAKEAWAYS:
Stellar evolution is a cosmic cycle from the formation of protostars and stars in cold molecular clouds, through their final collapses into remnants and stellar cores. This process creates heavier elements and sets the stage for the formation of exoplanets and the next generation of star formation.

Chemical bonding is a complex and challenging topic for both teachers and students. We will share our ongoing work to incorporate the SEPs into our units for chemical bonding and how we engage students in developing increasing complexity into their explanations and models of chemical bonds. We will discuss how our learning progression is informed by and addresses misconceptions identified by chemical education research. This sequence builds student understanding from atomic principles to bonding models and the macroscopic properties of substances which directly addresses standards HS-PS1-1 and HS-PS1-3, while introducing underlying concepts needed for HS-PS1-2 and HS-PS1-4. Our current work is to incorporate more explicitly the CCCs including a performance assessment adapted from Wonder of Science. Lastly, we will reflect on our next steps and identify both the benefits and difficulties in modifying units for the NGSS performance expectations.

TAKEAWAYS:
Attendees will learn how to apply a research-based curriculum sequence on chemical bonding into their classroom that incorporates both strategies and activities that we have developed or adapted to use the three dimensions of NGSS.

For Teachers, By Teachers -- A group of 25+ educators from the Midwest are currently developing a series of storyline units for science and agriculture teachers that engage students in developing explanations for agricultural phenomena and solving real-world problems. Students utilize the three dimensions of NGSS in each of the storylines as they learn about food systems, or the production, processing, distribution, and consumption of food products and interactions with the natural environment. During this session, participants will learn about storyline #2 which challenges students to figure out how different soils affect the kinds and quantities of food commodities that can be produced. Topics include: what is soil, effects of soil on plant growth, movement of matter and energy in soil, and how to decrease human impact on soils and biodiversity. Specific emphasis is placed on developing skills related to the Scientific & Engineering Practices and building Crosscutting Concepts.

TAKEAWAYS:
Participants will engage in activities that are part of a new storyline unit on how soil affects the types and quantities of food commodities grown. Topics include what is soil, the effect of soil on plant growth, movement of matter and energy through soils, and how to decrease human impact on soils.

Students utilize different components (enzymes, yeast, feed stocks, water] to produce ethanol and carbon dioxide through fermentation. Students develop a model and explain how ethanol is made to answer the focus question: "How can fermentation produce a renewable fuel source?" Students develop experimental models to generate data to construct explanations about relationships between components of the fermentation process and to predict how they can be manipulated to produce carbon dioxide. Students will design solutions to make the fermentation process as efficient as possible and generate the maximum amount of ethanol in a small bag environment. Participants will deconstruct a model of starch to examine enzyme and starch reactions to determine how starches change into smaller molecules. Attendees will participate in numerous hands-on activities centered around biofuel.

During our district's "austerity" years (around 2008) our supply budget was slashed and has not returned. Our Biology team developed low-cost wet-lab experiences for students to develop skills in experimental design, long-term data collection, graphing, and writing scientifically. These activities are used in our honors and regular biology courses. Check out one of our experiences- (sample of a whiteboard and a class set of the algae lab in our Biofuel Unit.) https://drive.google.com/file/d/1XMpQ5SsBw0YgU9frO2L4lKwv-L38BkQg/view?usp=sharing Students were tasked with maximizing algae growth over two weeks, measuring with turbidity, and then analyzing their protocol compared to the class. You can see not all were successful which leads to rich conversations.

TAKEAWAYS:
Bring home six low-cost, highly engaging lab experiences that can be supported with a minimal financial cost!

Education is one of five key elements of Social Determinants of Health that have a huge impact on quality of life. Ensuring good physical & mental health is essential to learning. While some schools have excellent health education programs, a large number have limited time and resources for providing health education. An efficiently effective method is to address health questions within the routine science curriculum. For example: In Biology: How does Gonorrhea become multidrug resistant? In Chemistry: How does the chemical structure of penicillin lead to its effectiveness? In Physics: How do seatbelts and airbags affect “Impulse” so crashes can be survivable? Answering these and many other questions provides health information to your students which can help them make more informed decisions. School leadership and science teachers are in an excellent position to promote curriculum incorporated, evidence-based health education using the practical solutions provided by Dr. Lucas

TAKEAWAYS:
Dr. Lucas will address essential topics such as sex ed., substance use, physical self care and mental health. He will offer effective strategies for incorporating these topics into your existing science curriculum to advance overall student well being.

We’re all passionate about science, and part of that passion stems from the fact that no other discipline is exploring the entire physical universe and making sense of our world. No other discipline can make predictions as accurately as science can! It’s so powerful and engaging that some misunderstand it and use it for purposes it isn't intended to be used for. Some even manipulate our students’ misunderstandings of what science is, creating enough confusion that our students believe in junk science, disinformation, or even deny science! As science educators, we sometimes get distracted by all the minutia on our plates and do not directly incorporate the NGSS Appendix H: Understanding the Scientific Enterprise in our work. Students find joy in “debunking” bad science and become future citizens who can sniff out scientific misinformation. We'll enhance activities with the scientific thinking that is developed from a deeper understanding of the nature of science.

TAKEAWAYS:
Become familiar with NGSS Appendix H and use it to enhance your classroom activities to develop sensemaking skills that help your students to identify logical fallacies and misinformation that are used in sloppy science, disinformation, and science denial in their everyday experiences.
