Chemical Potential: Staircase Demonstration
It's all uphill from here! Scholars examine the pattern of random particle motion up a staircase. The simulation shows how the linear increase in energy corresponds to an exponential decrease in particle concentration.

Don't Crack Humpty
Students investigate the engineering design process and the relationship between distance, time, and speed. Using a generic car base, small groups design a device that will protect an egg on or in the car as it is rolled down a ramp at...

Water Pressure Blaster
Third graders complete an experiment to introduce them to the concept of water pressure. For this water pressure lesson plan, 3rd graders create pressure in a water bottle and observe the force of water that is created.

Height of Bounce
Eighth graders determine the relationship between the height of bounce of a ping-pong ball and the height from which it was dropped. They are assessed on the ability to record and interpret data, graph data, make predictions, and make...

Proportionality: The X-Plane Generation
Students meet NASA researchers who describe the relationship between force, energy and motion. They discuss how NASA's experimental X-plane is being tested to make space travel more reliable and show how proportionality and ratios are...

May The Fastest Toy Win
Students determine which wind-up toy is the fastest. However, they can NOT race the toys. They must find another way. On the first day of the activity, students work in pairs or small groups to develop and write a plan.
