Learners observe projectile motion by launching wooden balls off of a table top. They set up a rubber-band launcher so that each ball experiences a consistent amount of force.

In this activity, learners investigate color vision as well as plan and conduct their own experiments.

Learners drop two different masses of play dough and observe how long it takes them to hit the ground.

Learners build a pendulum from a yo-yo, and then design their own experiment to determine what affects the pendulum's period of swing.

In this two-part activity, learners explore the Earth and Sun's positions in relation to the constellations of the ecliptic with a small model.

Learners experiment with water gel crystals, or sodium polyacrylate crystals, which absorb hundreds of times their weight in water. When in pure water, the water gel crystals cannot be seen.

These math posters have questions written on them, such as: How many colors can you name in a minute? or How many seconds can you balance on one foot?

In this math-based activity, learners will experiment to find how height and angle affect spatter and then use this knowledge to solve a crime.

On the first night, I saw 5 stars in the desert. On the second night, I saw 10… What do you think I saw on the third night? Combine arts and crafts, literacy, and math by making a counting book.

Learners examine the properties of light by experimenting with an LED-flashlight and polarizing filters. When two polarizers are used, they block all light when they are placed at right angles.

In this outdoor activity, learners work in pairs using their senses—especially touch—to learn more about individual trees.

In this activity, learners construct a projector out of cardboard to view their favorite images (such as storybook illustrations) on the wall.
