Level 3

This demonstration dramatically shows how not just the strength of a material, but how it is designed, is important when withstanding forces.

After completing Part 1, explore solar system formation, tides, and planetary rings using a spandex sheet.

Constructing this simple and inexpensive portable cellphone charger provides an introduction to soldering and electronics.

Practically, these units can be used for charging in regions of the world where grid electricity is not readily available.

Explore forces in a gravitational field using a spandex sheet and marbles.

This demonstration shows how gravity can be interpreted as the bending of spacetime due to massive bodies. Participants can identify gravity interactions, observe how the shape of the spandex corresponds to mathematical models, and make inferences based on object size, shape, and mass.

After completing this demonstration, present Part 2 to explore solar system formation, tides, and planetary rings.
