In this activity, learners test exhaled breath for carbon dioxide and learn how to use an indicator as a simple way to measure pH.

In this activity, learners discover how landfills affect the natural environment.

In this activity, learners explore how the application of nano-sized "whiskers" can protect clothing from stains.

Learners explore the endless possibilities of cardboard engineering in this open-ended STEAM activity. Practice being creative by building structures with no glue, only cardboard and scissors.

This is part 3 of the three-part "Crayon Rock Cycle" activity. Before starting this section, learners must have completed part 1: sedimentary rock and part 2: metamorphic rocks.

In this activity, learners play a card game that explores different size scales--macro, micro and nano.

In this activity on page 8 of the PDF, learners make a slimy substance very similar to mucus, and sprinkle it with glitter to imitate the way that allergens are trapped.

In this activity, learners explore how eating unhealthy food can damage a heart and arteries.

This fun and simple hands-on astronomy activity lets learners experiment with a bucket, stretchy fabric, marbles, and weights to discover some basics about gravity.

In this activity, learners explore how sound travels through solid objects better than through air. Leaners attach a metal clothes hanger to a piece of string and hold it to their ears.

In this activity, learners conduct a simple experiment to see how electrically charged things like plastic attract electrically neutral things like water.

In this activity, learners try to float ink on the surface of water to create a pattern and then capture it with absorbent paper.

In this activity related to Newton's Laws of Motion, learners build a boat powered by a propeller in the air.

Learners assemble a hot-air balloon from tissue paper. The heated air (from a heat gun) inside the balloon is less dense than the surrounding air and causes the balloon to float.

In this design challenge activity, learners explore the concept of biomimicry by using a natural organism's special features to design a new human object.

This fun and simple hands-on astronomy activity describes techniques scientists use to find planets orbiting other stars.

In this activity, learners interact with whale artifacts such as replicas of skulls, bones, teeth, and baleen (hair-like plates that form a feeding filter).

In this demonstration, cook a cake using the heat produced when the cake batter conducts an electric current.

In this activity, learners create and experiment with wind tubes. These tubes are a playful and inventive way to explore the effect that moving air has on objects.

Visitors use heat to shrink samples of polystyrene. They compare samples from containers that were shaped in different ways during manufacturing.
