In this activity, learners hook up a hair to a lever system and create a hair hygrometer to measure changes in humidity.

In this activity, learners explore the human influences on the carbon cycle and examine how fossil fuels release carbon.

In this group activity, learners act out key stages of the "ocean carbon cycle" (also known as the "carbonate buffer system") through motions, rearranging blocks and team tasks.

In this activity on page 7 of the PDF, learners investigate the solubility of gas in water at different temperatures. This experiment will help learners determine if temperature affects solubility.

Through discussion and hands-on experimentation, learners examine the geological (ancient) carbon cycle.

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

In this activity about combustion and energy, learners observe a burning candle in a sealed jar and the burning of white sugar.

This is a fun activity about the power of the Sun and the importance of using sunscreen to protect your sensitive skin from its rays.

In this activity, learners build a model of a self-sustaining habitat (growing grass and beans from seeds).

In this activity on page 7 of the PDF (Plants—The Green Machines), learners examine the effects that light and air have on green plants.

This activity features two connected hands-on activities about dinosaur bones.
