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, challenge learners to float a paper clip in a cup of water. Learners discover that a paper clip will sink in a cup of water, except when it is placed on a piece of paper towel.

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 activity about scale, learners investigate the world of the very small by cutting a 28 centimeter strip of paper in half as many times as they can.

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.

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

In this activity, learners use marshmallows and gum drops to construct seven models of molecules. Learners classify (solid, liquid or gas) and draw diagrams of the molecules.

In this quick activity, learners explore static electricity using a plastic comb, wool cloth, puffed rice, and a plastic bag.

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

In this introductory activity, learners discover that sugar and food coloring dissolve in water but neither dissolves in oil.

This fun astronomy activity allows learners to experience finding stars in the night sky that will eventually go supernova. This activity is perfect for a star party outdoors.

In this weather-related activity, learners make a portable cloud in a bottle.

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 about electricity, learners suspend pieces of tape from a straw to construct an electroscope, a device that detects an electrical charge.

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.

In this trick, learners discover how to stick a straw to the palm of their hand, window door, or anywhere using static electricity.
