3.2.3.B1.1: : Explain how movement can be described in many ways.

Free Fall Tower
Recreate Galileo's famous experiment by dropping objects off the Tower of Pisa. You can drop ping pong balls, golf balls, soccer balls or watermelons. Objects can be dropped in air or no air, with or without a parachute. The speed of each object is shown on a speedometer and a graph. 5 Minute Preview

Measuring Motion
Go on an African safari and observe a variety of animals walking and running across the savanna. Videotape the animals, and then play back the videotape to estimate animal speeds. Which animals run fastest? 5 Minute Preview
3.2.3.B2: : Energy Storage and Transformations: Conservation Laws
3.2.3.B2.1: : Explore energy’s ability to cause motion or create change.

Radiation
Use a powerful flashlight to pop a kernel of popcorn. A lens focuses light on the kernel. The temperature of the filament and the distance between the flashlight and lens can be changed. Several obstacles can be placed between the flashlight and the popcorn. 5 Minute Preview
3.2.3.B2.2: : Explore how energy can be found in moving objects, light, sound, and heat.

About STEM Cases
Students assume the role of a scientist trying to solve a real world problem. They use scientific practices to collect and analyze data, and form and test a hypothesis as they solve the problems.

Each STEM Case uses realtime reporting to show live student results.
Introduction to the Heatmap

STEM Cases take between 30-90 minutes for students to complete, depending on the case.

Student progress is automatically saved so that STEM Cases can be completed over multiple sessions.

Multiple grade-appropriate versions, or levels, exist for each STEM Case.

Each STEM Case level has an associated Handbook. These are interactive guides that focus on the science concepts underlying the case.
