Stoichiometry is a topic in foundational chemistry that is often difficult for students to grasp. In this lesson, students learn about stoichiometry from the perspective of making paint. The lesson plan brings together many chemistry topics that are often taught in siloed chapters: types of chemical reactions, balanced chemical equations, net ionic equations, limiting reactants, molarity, and solution stoichiometry. This lesson brings these topics together and students make sense of how the different topics are conceptually bound. The art component of painting a personal tile gives each student the opportunity for self-expression and the inclusion of each tile into a class quilt makes for a unique perspective of the collective.

TAKEAWAYS:
Student engagement in learning and understanding a difficult concept like stoichiometry is buoyed by inclusion of an art component and a descriptive narrative that allows for open expression of a student's interests or culture.

Coaching Science Olympiad 30+ years and my science teaching cousin still a rookie, we offer tips and tricks on team startup or management. Join us to hear how I took a tiny Nebraska school to win B and C Divisions at Regionals my first year at Arcadia. Having been a veteran coach at four public schools, this amazing educational science event molded careers for my students, cousin, and four children. My cousin started a team in western Nebraska which added travel challenges across our state. We will share ideas on how to manage 2 teams of 30+ students to compete in 24+ events that coaches rarely get to see. Nebraska coaches often make tests for 2 events in 4 time slots to judge. Balancing team preparation and meeting NGSS/state science standards is a challenge while teaching a full day with 3-7 preps. The NE Director asked me to mentor more S.O. coaches so here we are. Teachers will be enlightened with a poster, slide show, paper examples and 3-D visuals to help coaches find success.

TAKEAWAYS:
Attendees will gain ideas to start their own Science Olympiad Team/s. How to select students for various events to earn team points in each, make user-friendly maps with schedules, reminders and information students can follow, and build unity by wearing team designed school shirts.

Hands-on lab experiments are crucial for students to develop proficiency with the science and engineering practices in the Next Generation Science Standards, but traditional labs often require hazardous materials, expensive equipment, long lab times, and dedicated facilities, leaving them out of reach for many schools. Paper microfluidics provides a safe, low-cost, and easy-to-use platform to do hands-on chemistry experiments without specialized equipment or lab spaces. MICRO Project experiments use paper microfluidics to teach inquiry-based chemistry labs. Each MICRO lab is designed to engage students in science and engineering practices and includes instructor notes, customizable pre- and post-lab questions, student procedures, and background on a relevant issue of equity and justice. These labs have been used by thousands of students at universities, community colleges, and middle and high schools. Participants at the Share-a-Thon will perform a MICRO titration lab.

TAKEAWAYS:
Attendees will learn how to integrate authentic scientific practices into safe, hands-on, low-cost lab experiments.

For the purposes of the STEM Share-a-Thon, NCSE will have two mini-stations set up to provide quick, meaningful previews of our evolution and climate change lessons. We will have a variety of student and teacher handouts ready to take home for immediate use in the classroom, and a variety of SWAG to help spread the word about scientific literacy and our evidence-based approach to NGSS storylining. The National Center for Science Education's mission is to ensure all students have access to a sound science education, regardless of societally contentious regional topics like evolution and climate change. Our lessons were developed for teachers by teachers and have been extensively field-tested over the past three years. As we are a non-profit organization, all our resources are free. For more information, and to check out the variety of lessons we will have available at the Share-a-Thon, go here: https://ncse.ngo/supporting-teachers/classroom-resources.

TAKEAWAYS:
Scientific literacy and critical analysis of verified evidence are more important than ever in the secondary classroom. NCSE has developed lessons to resolve common misconceptions encountered online and through social media. All resources are free, NGSS-aligned, and readily available online.

As a district, we have worked to ensure that all courses have three dimensional standards. We currently teach all of the NGSS standards by the completion of sophomore year. Our freshmen physical science course teaches the physical science standards and one-half of the earth science standards, while our sophomore biology course teaches the biology standards and the other one-half of the earth science standards. To meet the rigor of NGSS, our elective courses such as Chemistry, Physics, Environmental Science, Earth Science, Forensics Science and Plants and Propagation have all built upon the NGSS standards in content, along with identifying Science and Engineering Practices and Crosscutting Concepts. Our goal would be that participants would leave with a process in which they could do the same. Our process has been influenced by the 5 tools training as well as many of the NSTA publications designed to lead teachers and teacher leaders in standard development.

TAKEAWAYS:
Participants will leave with examples of elective standards that are three-dimensional.
