This activity has students/participants act as particles. To start, participants are given baseline information about how attractive forces between particles can vary from very strong to negligible, & that particles are always in motion. Participants then split into three groups, strong, moderate, & weak forces. To model very strong forces participants link arms at the elbow, for moderately strong forces they hold hands, & for weak/negligible forces they can only hold each other’s pinky fingers. Participants start far apart & move very slowly to model a very cold temperature. At this speed, all of the participants are able to catch onto each other & form an organized structure (solid). With each iteration the participants move faster; this results in the weak-force group not being able to form a structure (gas), the moderate-force group being clumped together but not organized (liquid), & the strong-force group still being able to form an organized structure (solid).

TAKEAWAYS:
Students will not only know the properties of solids, liquids, and gasses, but will be able to give in-depth explanations as to WHY the properties are different by behaving as the particles at different temperatures and with different attractive forces.

Participants will learn about forms of energy and their transformations by experimenting through six stations. Stations cover potential and kinetic energy, endothermic and exothermic processes, radiant energy, thermal and motion energy, chemical energy, and electrical energy. Within each, there are multiple activities to showcase the energy transformations occurring. The stations will be set up with materials needed, a hypothesis prompt, procedure list, and a station guide for recording data. For example, a yo-yo stores gravitational potential energy when it is in your hand until it drops. When it drops, the yo-yo transforms the potential energy into motion. At the end of experimenting, participants will review a “What’s Happening” sheet that explains what form of energy and energy transformation occurred in that station, as well as how it’s tied to the real-world applications. NEED activities are free and easily differentiated at the elementary, intermediate, and secondary level.

TAKEAWAYS:
How to help students master forms of energy and their transformations and how it can be visualized in the world around them.

The drinking bird is a classic heat engine toy that has been featured in popular culture. Although the cause-and-effect relationship for this phenomenon is clear, the mechanism for its repetitive movement is puzzling for most students. In this workshop, participants will use investigative and sensemaking practices to explore the drinking bird phenomenon. This interactive 3-D lesson is in alignment with the goals, standards, and practices of the NGSS. In addition, tips to enhance the development and use of student explanatory models will be featured.

TAKEAWAYS:
Workshop participants will experience an interactive and engaging three-dimensional lesson that is in alignment with the goals and practices of the Next Generation Science Standards. In addition, tips to enhance the development and use of student-created explanatory models will be featured.
