In this activity (on page 2 of the PDF), the learner places a golf ball between salt water and colored fresh water. The golf ball is not as dense as the saltwater.

Ocean acidification is a problem that humans will have to deal with as we release more and more carbon dioxide into the atmosphere.

The "Rocket Reactions" activity is an exciting way to learn about how materials interact, behave, and change.

Learners observe a sealed test tube containing a small amount of solid stearic acid.

Learners use a commercially available toy to experiment with density. They fill a chamber in the toy submarine with baking powder and release it into a tank of water.

Learners observe a bottle containing water and oil. They are invited to pick up the bottle and mix the contents together.

In this activity, learners use heat to separate zinc and copper in a penny. This experiment demonstrates physical properties and how physical change (phase change) can be used to separate matter.

In this chemistry activity (on page 2 of the PDF), learners make a layered drink with liquids of different densities.

Do grapes, yes the grapes from the grocery store, move in the presence of a very strong magnet?

Learners mix liquid water with solid cornstarch. They investigate the slime produced, which has properties of both a solid and a liquid.

Learners discover that their breath contains carbon dioxide, one of the pollutants found in car exhaust.

In this chemistry demonstration, learners will discover that phenolphthalein is an acid/base indicator. One learner will read a poem about four witches making a potion.

In this activity on page 4 of the PDF, explore the unique molecular structure and conductive nature of graphene. Learners construct a circuit with a battery and LED bulb.

In this activity (on page 2 of the PDF), learners explore surface tension by adding pennies to cups which are "full" of plain water or soapy water.

Learners measure a bottle full of air, and then use a vacuum pump to remove the air. When they re-weigh the bottle, learners find the mass is about 0.8g less.

Learners use filter paper and water to analyze six different markers. They mark the paper with ink, and dip the paper in water. The water travels up the paper and dissolved ink travels with it.
