In this design challenge activity, learners use two helium-filled balloons to build a blimp that can travel in a straight path across the room.

In this two-part activity, learners work in pairs to examine the four basic stages of a turbine engine.

Working in groups, learners model the continuous destruction and creation of ozone (O3) molecules, which occur in the ozone layer.

In this activity, learners examine raindrop bottles (prepared ahead of time) to observe in slow motion the behavior of falling droplets and explore concepts such as drag and terminal velocity.

Learners explore the Bernoulli effect by building an airfoil (airplane wing) and making it fly.

In this activity, learners are introduced to robotic submarines called gliders. Learners make “gliders” from plastic syringes and compare these to Cartesian bottles and plastic bubbles.

This activity models the way Landsat satellites use a thermal infrared sensor to measure land surface temperatures.
