Parachute Parade
Sail to the ground with a parachute activity! Kids construct parachutes out of household items and a toy figure, after brainstorming the best way to reduce drag. Once they test their parachutes, they can adjust their projects to...
Magic of Physics
Wave Machine
Three main factors determine the wave height experienced in the ocean. Scholars use a virtual simulator to alter wind speed, fetch, and duration. Each combination creates a unique wave measured in significant height.
