Optional Science Demos 

Rocket Reactions – Exciting way to learn about how materials interact, behave, and change. Participants will make baking soda and vinegar “rockets,” launching plastic caps into the air, and experimenting to discover the best mix of fuel for their rocket.   


What’s in the Water – Participants use tools to solve a mystery: what chemicals and compounds are in a sample of water. By investigating with a variety of tools and techniques students understand how chemistry can help us explore, understand, and solve problems.   


Nebula Spin Art – Students will gain an introduction to the night sky and the wonder of nebulas. Depending on grade level, participants will make their own nebula in a jar or nebula spin artwork to take home.  


Moon and Me – This fun demonstration is all about Earth’s closest neighbor: the Moon! Participants will learn about lunar cycles, the latest NASA missions, and how scientists are preparing to live on the Moon’s surface. Take-home activity will depend on participant grade level.  


Owl Pellet Dissection – Using proper tools and REAL pellets, students will investigate the fascinating digestive system of one of nature’s fiercest predators. Typical findings include mice, vole, mole and small bird skeletons.
