Students follow the steps of the engineering design process as they design and construct balloons for aerial surveillance. After their first attempts to create balloons, they are given the associated Estimating Buoyancy lesson to learn...

SPRK STEM challenges are fun, interactive activities that challenge students to use creativity and team-work to move through simple steps of the design process in order to build Sphero-based creations. The Hydro-hypothesis challenge...

Each student uses a small quantity of modeling clay to make a boat that will float in a tub of water. The object is to build a boat that will hold as much weight as possible without sinking. In the process of designing and testing their...

Predict and test everyday objects as to whether they sink or float.

Students studying plate tectonics will better understand its concepts with this virtual experiment that tests how plates move on the surface of the earth. Temperature, composition, and thickness of plates can be changed to create new...
