In this activity, learners predict where a ball will go after it bounces off another object. Learners discover that the motion of objects is predictable based on laws of motion.

In this activity, learners work with an adult to build a rocket and launcher out of a plastic 2-liter bottle, flexible plastic hose, plastic tubing, toilet paper tube, and duct tape.

In this activity, learners explore how objects can have positive, negative, or neutral charges, which attract, repel and move between objects.

In this electrochemistry activity, learners will explore two examples of electroplating.

In this activity, learners determine the shape of an unseen object by bouncing a ball off the object.

Learners test their "light-smarts" by playing a game called "Light Quest!" The game board represents an atom and each player represents an electron that has been bumped into the atom's outer unstable

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, learners add food coloring to hot and cold water to see whether heating or cooling affects the speed of water molecules.

This fun and simple hands-on astronomy activity lets learners explore what happens when a star explodes.

What causes frost to form on the outside of a cold container? In this activity, learners discover that liquid water can change states and freeze to become ice.

In this activity, learners explore atoms as the smallest building blocks of matter. With adult help, learners start by dividing play dough in half, over and over again.

This fun and simple hands-on astronomy activity illustrates the value of supernovae in the universe.

In this activity, learners apply a dissolving test to known crystals to identify the unknown. Since the unknown is chemically the same as one of the known crystals, it should dissolve similarly.

In this lesson, learners cut paper into very small pieces to explore the small size of quarks, the smallest thing we know of on Earth.

In this activity, learners place cards featuring biological structures in order by their relative size from largest to smallest.

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

Learners add calcium chloride to a baking soda solution and observe an increase in temperature along with the production of a gas and a white precipitate. These are all signs of a chemical reaction.

Learners mix vinegar and baking soda to produce a gas. With the addition of a bit of liquid soap, the gas becomes trapped in measurable bubbles.
