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. 

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. 

Participants use a hair to show how light can interfere to produce a diffraction pattern.     

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. 

Construct a pinhole projector to introduce participants to the basic properties of light. This tool can then be used to view eclipses or other bright sources.
