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

In this activity, learners add different liquids to water and apply their working definition of “dissolving” to their observations.

In this activity, learners explore Boyle's Law and discover that water will boil at room temperature if its pressure is lowered.

In this activity, learners use information gathered from a variety of sources to design and make their own insect.

In this activity, learners will measure the length of a shadow and use the distance from the equator to calculate the circumference of the earth.

Learners examine the manufacturing process while they make picture frames from cereal boxes.

In this physics activity (page 6 of the PDF), learners will explore how static electricity affects surrounding objects.

In this activity, learners follow simple directions to explore and create platonic solids.

In this math activity (Page 11 of the Dining Out! PDF), younger learners count out the total amount of money needed to purchase trail mix using the fewest number of bills/coins possible.

In this activity, learners imitate the way vocal cords work by building a model from a plastic cup, rubber band, and a straw.

In this activity about tangrams, learners print and cut out their own tangram shapes and solve puzzles by fitting these geometric pieces together in a variety of ways.

In this activity, learners will test soil content using their sample, some water and a container that seals.

In this activity, learners create a toy that demonstrates the First Law of Thermodynamics or the Law of Conservation of Energy.

In this activity, learners examine the culture and history of the tomb site.

In this activity, learners heat and cool carbonated water to find out whether temperature has an effect on how fast the dissolved gas leaves carbonated water.

Challenge popular misconceptions, learners explore how a mirror actually reflects an image in this activity.

In this activity, learners explore motion and airflow by setting two aluminum cans on their side and blowing air in-between them.

Learners combine different plant solutions -- made from fruits, vegetables, and flowers -- with equal amounts of vinegar (acid), water (neutral), and ammonia (base).

In this activity, learners investigate sound and vibration by making a "bee hummer"--a toy that sounds like a swarm of buzzing bees when you spin it around.

In this science/art activity, learners create an insignia or emblem for a planet exploration mission.
