Over the last few years, access to digital resources to capture student understanding of chemistry concepts has greatly increased. This technological shift, along with a focus on the use of storylines to engage students in chemistry, provides an opportunity to implement digital interactive notebooks. Through the use of various on-line platforms, student beliefs and understanding can be documented and tracked over the course of a storyline. Digital notebooking is a dynamic process that integrates different learning experiences to challenge and reinforce student understanding. This method actively engages students in a manner that encourages discussion and collaboration. Support is built into the digital notebook for absent students and those that need additional resources to understand a concept. This session provides an overview of the digital interactive notebook creation, along with guidance for educators to take this process and use phenomena relevant to their students.

TAKEAWAYS:
This session will provide a brief overview of how I use digital interactive notebooks in my classroom, along with guidance on how educators can begin the process of building their own. Resources and editable chemistry notebooks will be shared that focus on different chemistry phenomena.

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.

After the pandemic, we wanted to bring in as many hands-on, real-life chemistry experiences to our students as possible. After watching labs through a screen and sending materials home, our team had a new passion to get as many labs and investigations in as possible! What that passion evolved into was working on non-traditional assessments that required students to plan and carry out an experiment for an assessment in addition to the labs during class time instead of the traditional “in your seat” with paper and pencil assessment. We wanted to give our assessment meaning and bring purpose back to the labs. Presenters will share several different formats that we have tried as we went through year one of implementing SEP3 Planning and Carrying Out an Investigation.

TAKEAWAYS:
Presenters will share how they developed non-traditional assessments related to SEP3 Planning and Carrying Out Investigations in their standards-based grading chemistry curriculum. Presenters will share recommendations/challenges for teachers to think about as they implement SEP3 in their classrooms.

TikTok is all the rage, and student spend a large amount of time on TikTok. Because of this, students do not always like traditional methods of receiving information (notes, lectures, demonstrations, labs). Additionally, according to Pew Research, 26% of 18-29 years old get their news (whether accurate or inaccurate) on TikTok. This number is probably higher for younger ages. Because students spend so much time on TikTok, they are used to getting short (less than 1 min) snippets of information in an engaging environment. In order to better serve our students, educators need to know how to use TikTok to their advantage to inform students. Tiktok can be used to share information with students (as photos or videos) and can serve as a great tool for formative and summative assessments (i.e.: students sharing information about their experimental results, taking polls, analyzing other TikTok's for their educational value).

TAKEAWAYS:
Attendees will learn how to use TikTok for educational purposes; including disseminating information to students via TikTok and using TikTok as a formative and summative assessment tool for high school and post-secondary students.

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.

Models engage students, promote critical thinking, and help students connect abstract concepts to real-world phenomena. This session will promote using the science and engineering practice of developing and using models as a technique to explore concepts, promote sense making, and demonstrate student understanding. Presenters will include modeling techniques that have been successfully used in both rural and urban chemistry classrooms to help students better understand complex concepts within storyline units. The use of simulations, hands-on activities, physical manipulatives, drawings, and technology will be demonstrated. The benefits of models used as an equitable tool will be examined using student data and examples. Sample chemistry storylines will be used to show how student coherence builds throughout the unit with the use of models. Strategies for teachers will be provided to help students develop better models, and a discussion of formative assessment value will be stressed.

TAKEAWAYS:
Attendees will leave with various modeling strategies to implement into their chemistry courses. This will promote student sensemaking and more equitable evaluations of student ideas.

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.

My first years of teaching Physics at Title 1 schools in Memphis were challenging. Many of my students were very behind, especially in math. However, I developed 5 strategies to make learning physics accessible and they completely transformed my classroom. 1. “Building Block” Method The biggest breakthrough in my classroom was breaking long problems down into building blocks. I will show how to do this with a sample forces unit. 2. Pre-manipulated equations I will share an equation sheet that shows all forms of each equation. It is a game-changer for students who struggle with algebra. 3. Setting-Up for Success I will model a consistent way to help students stay organized on different types of problems. 4. Simplifying Motion I will illustrate how to solve motion problems using simpler notation and simpler equations. 5. Simplifying Circuits I will show how to use the “routes method” so students can solve most circuits in a more conceptual way.

TAKEAWAYS:
Teachers will come away from this session with strategies that they can immediately implement in their classrooms to make physics more accessible and engaging, especially for their lower-level learners.

The Stan-X network is a world-wide partnership of public and private schools that work together to provide research-based learning experiences for students (https://stan-x.org). Through collaboration with the research group led by Dr. Seung Kim at Stanford University, the schools have adopted a fruit fly-based program that provides opportunities for authentic research that generates high-quality data and resources impacting the community of science. Stan-X program elements can fit flexibly into almost any science curriculum at middle or high school grade levels. In our session, we will detail the development and growth of our program and describe examples of courses that have been developed in schools in the U.S. and abroad. We will also describe how Stan-X works with schools to fund program creation and develop instructor skills for guiding students through authentic, open-ended research, while developing sufficient autonomy to modify or expand research-based science teaching.

TAKEAWAYS:
Through Stan-X, middle school and high school students learn science through authentic, open-ended, publishable research. Coordination between schools, both public and private, across the world can enhance scientific learning and research opportunities for your students and for teachers!

How can we assess the quality of sampling and variability of the data to help us in decision-making? The various metals and alloys used in the minting of the penny over the years will provide for rich explorations, which are part of the chemistry curriculum. We will highlight the important cross-disciplinary aspect, linking the science content (mass/chemical composition) to the mathematical models outlined in the NGSS section on Systems and Models to show how to use it to simulate systems and interactions. Through hands-on activities and the use of technology, participants will explore a variety of data sets and use this knowledge to better understand and use statistics to make accurate and fair arguments related to everyday topics. We will explore how the sample mean varies from sample to sample. While this is considered one of the more challenging topics for quality control, we will illustrate the concepts though some basic sampling of the typical age and mass of the U.S. penny.

TAKEAWAYS:
Participants will use real data to develop mathematical models and learn how to test our hypothesis by performing an experiment and analyzing the results, combining chemical analysis with statistical sampling for a cross-curricular approach.

Scientific Theater might seem like an oxymoron, but over my decade-plus in high school education, it has become a favorite of my students. The goals of this experience are to encourage the attendees/students to be creative in trying to explain sometimes complicated concepts, and to realize that written words and slide presentations are not the only way to explain something. In this workshop, attendees will be given the opportunity to experience Scientific Theater exactly as my students do, by creating their own one-act play explaining a chemical concept. The concept may be one of their own choosing, or there will be several to choose from. After choosing, attendees will split into groups of four, at which point they will collaborate to develop and write a 3-minute play that they best feel illustrates their concept. At the end of the session, volunteer groups will be invited to perform, and it is hoped that the attendees will have seen theater as the powerful and enjoyable tool it is.

TAKEAWAYS:
Attendees will collaborate to create their own plays to describe a scientific concept. After discussion and rehearsal, volunteers will be asked to perform their masterpieces in front of the group. By doing so, attendees will be able to take what they have learned back to their classrooms.

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.

Chemical equilibrium is a central topic to the understanding of both Chemistry and Biology, yet students have many misconceptions. The NGSS standard HS PS1-6 covers this important topic. In a recent AP Chemistry Exam, the vast majority of students did poorly on the topic and had misconceptions about equilibrium; 73 % of the students received a zero or had no response to the equilibrium question. Students are most familiar with equilibrium problems and experiments where the K value is small; usually less than one. Exam questions dealing with a large K value cause the majority of students to do poorly. In this presentation, participants will take part in a “hands-on” inquiry activity with an equilibrium having a large K value. Participants will learn methods to overcome student misconceptions of equilibrium. Join this workshop to take an inquiry lab back to use in your classroom. Handouts will be provided. There will be time allotted for participant questions.

TAKEAWAYS:
Participants will learn to use Inquiry to overcome student misconceptions about chemical equilibrium.

Stop-motion videos can be used to show what is happening at the particulate level for different types of chemical reactions, bond enthalpy calculations, and electron excitation in light emission. TV theme song parodies can be used as a way to assess student understanding of a variety of chemistry topics. Sketchnotes can be incorporated to demonstrate knowledge of a particular lab, chemistry unit or short article which pertains to the topic being covered in class. Students also write children's books to showcase their understanding of climate change and ocean acidification. Finally, lab based art projects are a fun way to begin or end a unit of study and the student work can then be displayed in the classroom.

TAKEAWAYS:
Participants will leave with a variety of ideas about how to incorporate sketchnotes, stop-motion videos, songs, painting, and storytelling into their chemistry classrooms.

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.

SPEAKERS:
Pamela Perry (Lewiston High School: Lewiston, ME)

This session will provide two example wet lab assessments and information to design one for the general and college/AP chemistry classroom. Both labs were our summative assessment for our molecular structures unit (topics: polarity, intermolecular forces, Lewis structures) and our measuring matter unit (topics: density, metric units, relationship between mass, volume, and temperature). For the molecular structure unit assessment, students determined the polarity of acetone, water, ethanol, and vegetable oil by testing solubility, evaporation rate, surface tension, and drawing Lewis structures. Students wrote a CER to classify each compound as polar or nonpolar. For our measuring matter lab assessment, students had an unknown metal or liquid and had to calculate density and classify the unknown substance and wrote a short CER. Grading can be traditional or SRG.

TAKEAWAYS:
There are numerous ways to assess besides traditional paper and pencil tests in chemistry. This session will focus on using labs and writing CERs based on lab data as an assessment for concepts.

various demonstrations will be used to continue to compare and contrast types of solids (materials) and their bonding and properties. For example, (through video) a ceramic alumina rod and metal aluminum rod will be heated to showcase differences in melting point, conductivity, and density. Teachers will also participate in an activity that precipitates copper crystals from copper sulfate. This particular activity mimics how native metals can crystallize in the earth crust naturally. In addition, teachers will participate in a lab that shows how metal atoms can easily be mixed to make an alloy. The concept of solid state diffusion will be discussed.

TAKEAWAYS:
Attendees will learn how to teach basic chemistry concepts using common everyday materials like metals, ceramics, glass, and polymers. Hands-on STEM activities, demonstrations, and labs will make learning these chemistry concepts more engaging and relevant.

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.

This is a full tour of an astronomy research project done through NITARP (NASA Infrared Teachers Archive Research Program), which pairs Caltech astronomers with STEM teachers for authentic research using data from various observatories. The project presented here is a search for Young Stellar Objects (YSOs) in IC417 (the “Spider and Fly”) nebula. We’ll share how candidate objects were found, how object lists were generated and downloaded, how objects were identified and confidence values assigned. We’ll share how to make and interpret color-color plots, color-magnitude plots, spectral energy distribution plots and more. Most importantly, we’ll share how the astrophysics of star formation reveals itself in spectral data. And how confounding factors, such as dust in the interstellar medium, also show up in the data and can be compensated for. By attending this presentation, educators will be able to share a truer picture of the work of astronomers with their students.

TAKEAWAYS:
The participants will step through an entire astronomical research project from inception through data gathering, data vetting and processing, results, and publication. This will deepen the participant’s understanding of research and equip them to bring astronomical research to their school.

Copper is used in plumbing, coinage, and electrical wiring; yet we often take this element for granted. Copper has been known since at least 9000 BC, but many of its reactions and properties have only been determined in recent centuries. This inquiry requires students to: research the chemical reactions of copper (redox, double displacement, and decomposition), apply prior knowledge of stoichiometry and conservation of matter, analyze a copper solution using spectroscopy, and use proper laboratory techniques and skills. NGSS standards HS PS1-2, HS PS1-5, and HS PS1-7 will be addressed. Participants will: research and design an Inquiry experiment, use technology to collect/analyze data, & visualize what occurs on the submicroscopic level by employing particulate drawings. Join this workshop to take home a two-unit inquiry lab which is a perfect beginning-of-year lab and end-of-course lab practical. There will be time allotted for participant questions. Handouts will be provided.

TAKEAWAYS:
Participants will take part in a “hands-on” Inquiry experiment, use technology to collect/analyze data, and visualize what occurs on the submicroscopic level in copper chemical reactions by employing particulate drawings.

The impact of battery operated cars have become a hot topic as energy alternatives are explored. Unfortunately, few students get exposed to the true nature of a Voltaic Cell and the vital workings of the transfer of chemical energy to electrical energy through oxidation-reduction reactions. After a junior high demo, Physical Science and Chemistry classes don't relate the function of metals in their tug-of-war with electrons within a Redox reaction. Working with an ELL Specialist, Science Specialists created a series of lessons that incorporate phenomenon, asking questions, creating an investigation, data analysis, justification of their data through science research and application to real world analogous phenomenon. These have been tried in Arkansas Physical Science and Chemistry classrooms. To improve the efficiency and effectiveness of batteries, the next generation must engage on the issue. The answers may come from the next William Kamkwamba not the AP Chem class.

TAKEAWAYS:
When life gives you lemons- make a battery! Educators will see an inclusive approach incorporating a demo to explore how a battery operates. It will relate the simple to the complex Redox reaction with supports and scaffolded instruction to best meet the needs of all learners.

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!

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.

Stoichiometry is a topic that many teacher find difficult to teach and for many students, difficult to learn. In this project-based workshop, students will learn stoichiometry principles from the perspective of making paint. Paints are made up of three components: a pigment, a binder, and a thinner. In the water-based paint created in this module, the binder is calcium carbonate, an insoluble precipitate made from the double-displacement reaction between aqueous solutions of calcium chloride and sodium carbonate. When mixed in stoichiometric amounts, an insoluble precipitate, calcium carbonate, forms. Students use stoichiometry to quantify the correct amounts of aqueous reactants to make a desired amount of binder, then mix their own paint using pigment and water as a thinner. The project culminates in a class quilt made up of students' individually painted tiles.

TAKEAWAYS:
Stoichiometry does not have to be an anxiety-producing, tear-jerking unit. When taught in chewable chunks, students gain an appreciation for its importance in daily life. In this workshop, students learn concepts that are tied to an end-product art project.

Visible three-dimensional learning classroom connections can be difficult to assess. In this session, participants will use real-world data collection to determine a phenomenon: why salt is added to freezing roads and when making homemade ice cream, but also is added to boiling water when making pasta. Participants will use the data collected to argue with evidence while creating a visible molecular-level diagram of what occurred. This model will be used to assess student learning of why those phenomena exist.

TAKEAWAYS:
How to use SEPs to drive student instruction and molecular-level modeling of processes using data to support claims.

Goodbye, grading labs and lab reports -- Hello, lab practicals! Come learn how we’ve planned, implemented, and graded lab practical assessments in our SBG AP Physics 1 course. They are quick, individual, hands-on, aligned to science and engineering practices, and appropriate for an AP course.

TAKEAWAYS:
We will share how we’ve developed non-traditional lab assessments related to each unit in our standards-based grading AP Physics 1 curriculum. Presenters will share examples, recommendations, and challenges for teachers to think about as they implement lab practicals.
