In this activity, learners test to see if carbon dioxide is present in the air we breathe in and out by using a detector made from red cabbage.

Just like birds, some dinosaurs had air-filled (pneumatic) bones, which made the dinosaurs' skeletons lighter.

In this activity, learners make different shapes that hold exactly one mole of gas (air).

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.

In this chemistry demonstration, acid rain is simulated in a petri dish.

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