This activity provides a hands-on experience with a scale model, a relatively high viscosity fluid, and feeding behaviors.

In this simulation, learners use M&M™ candy to explore radioactive isotope decay.

In this design challenge activity, learners build a shock-absorbing system that will protect two “astronauts” when they land.

In this activity, learners observe how salinity affects the freezing point of water by making and enjoying ice cream.
