Learners of light will construct a contraption in which light is passed through a prism and shone into a box. The temperatures at different points along the path and outside of the path of light. The intent is to imitate William...

We taste with our taste buds, so why do flavors change when we have a stuffy nose? Scholars experiment with taste testing while holding their noses and then while smelling. They record their observations in pairs and come together to...

Ready, aim, fire! Launch to a new level of understanding as scholars build and test their own catapults. Learners explore lever design and how adjusting the fulcrum changes the outcome. 

Stability is key when building a bridge. Scholars explore the forces acting upon bridges through an analysis of Newton's Laws and Hooke's Law. The activity asks individuals to apply their learning by building a bridge of their own.

Bridge the gaps in your knowledge of bridges. Individuals learn about bridge types by building models. The activity introduces beam bridges, arch bridges, truss bridges, and suspension bridges.
