Elementary (ages 5-10)

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

Participants learn about impulse by building vehicles to drop eggs in. 

A sugar-water solution is used to create a liquid with a variable index of refraction. Participants learn about solutions, gradients, and refraction.

Students learn about glass, how glass is formed, and under what conditions that can occur.

By constructing a simple straw “oboe,” participants learn about sound waves and closed pipe resonance. 

This workshop uses marshmallows to teach participants about waves and to calculate the speed of light. 

This demonstration provides a three-dimensional visualization of magnetic field lines using ferrofluid.

This demonstration presents viewers with an example of reflection and refraction and describes difference between the two.

This surprising demonstration illustrates the relationship between densities and buoyant forces.

This demonstration provides a visual for how the diversity of matter affects interactions between different materials. The participants will be able to view a visually striking, easy-to-assemble display of various solids and liquids that tend to separate from one another due to their densities. The demonstration goes on to explain how this relates to the different states of matter, and makes a mention of the buoyant forces responsible for making objects float.

This demonstration shows how light changes paths when travelling through different materials. Snell’s Law and the critical angle are explored using lasers and water.
