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 make pykrete by freezing a mixture of water and a material like cotton wool, grass, hair, shredded paper, wood chips, or sawdust.

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

Heat makes some materials expand, and it makes others shrink.

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 thread gumdrops together to make a model of a polymer.

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.

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

In this activity, learners investigate convection by using food coloring and water of different temperatures.

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 activity on page 14 of the PDF (Rethinking the 3 R’s: It’s Easy to be Green), learners turn plain pieces of recycled plastic into shrunken works of art.

This lesson focuses on how to measure at the nanoscale and provides learners with an understanding how small a nanometer really is.

In this activity and/or demonstration, learners illustrate visually and physically that air has weight. Learners balance two equally-inflated balloons hanging from string on a yard stick.

In this activity, learners make their own rock candy. Crystals will grow from a piece of string hanging in a cup of sugar water. The edible crystals may take up to a week to form.

In this activity, learners experiment with surface tension using everyday household items such as strawberry baskets, paperclips, liquid dish soap, and pepper.

In this activity, learners light an LED with five cents. Learners use two different metals and some sour, salty water to create a cheap battery.

In this activity, learners investigate the properties of plastic bags. Learners find out what happens when they slowly push a pencil through a plastic bag filled with water.

This is a quick activity (on page 2 of the PDF under Hockey Sticks Activity) about how the arrangement of carbon atoms determines carbon's different properties.

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