W.I.S.H. STEM Challenges

  • Exploding Chalk

    This is an easy, safe, and fun way to learn about chemical reactions using baking soda and vinegar and what happens when gases produced by that reaction is trapped within an enclosure.

  • Alka-Seltzer Lava Lamp

    Oil and water are two liquids that are immiscible – they will not mix together. This is due to oil and water having different densities.

    Alka Seltzer has a different chemical reaction to each liquid, causing a fun chemical reaction similar to a lava lamp!

  • STEM Prism

    Create a water prism using a clear container and water. Learn about the properties of light and how it bends and refracts as it passes through different mediums.

  • Ice Cream

    Discover how energy causes matter to change in to yummy treat!

    This project shows how to change a liquid form of matter into a solid by changing the temperature.

  • Balloon Rocket Challenge

    To build a balloon-powered rocket and test its speed and distance.

  • Slime!

    Slime!

    Investigate the interesting chemical properties of slime to understand the cross-linking process between polymer chains that form slime.
