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

In this chemistry activity, learners fill two test tubes with a solution of "artificial stomach fluid," consisting of hydrochloric acid in the same concentration as in human stomachs, some soap to cre

In this activity, learners use a flashlight, a glass of water, and some milk to examine why the sky is blue and sunsets are red.

In this kinesthetic activity that demonstrates pressure, learners act as air molecules in a "container" as defined by a rope.

In this activity (on page 1), learners role play as atoms to explore how atoms can be rearranged to make different materials.

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

In this activity (on page 7), learners explore the meaning of a "carbon sink." Using simple props, learners and/or an educator demonstrate how plants act as carbon sinks and how greenhouse gases cause

In this activity, learners explore the history of making objects from glass and artistry of Dale Chihuly.

This online interactive has three activities in the NanoLab (press the upper right button): Build, Zoom, and Transform.

In this activity, learners act as water molecules and travel through parts of the water cycle to discover that it is more complex than just water moving from the ground to the atmosphere.

This kinesthetic science demonstration introduces learners to four states of matter: solid, liquid, gas, and plasma.

In this experiment, learners use a blow dryer and water bottle to observe and record changes in air pressure caused by changes in temperature.
