Level 2

Liquid Nitrogen Ice Cream

Explore the properties of liquid nitrogen while making a tasty treat. This demo is great for chapter socials and smaller outreach events.

Tuning Fork Workshop

Tuning forks are one of the few instruments that resonate with one distinct frequency. Create a workshop with tuning forks with this variety of quick, fun demos ranging from visualizing sound with lasers, to watching energy transfer through pendulums.

Homopolar Motor

Participants learn the everyday science of electric motors in this fun and engaging workshop activity. 

Impulse on Eggs

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

Variable Index of Refraction

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

Straw Oboe

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

Density Column

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.

Light Fountain

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. 

Eclipses: Earth-Moon-Sun Model

This demonstration uses a model of the earth-moon-sun system to explain why eclipses occur. This demo is useful for illustrating why total solar eclipses are rare.
