In this simulation activity, learners observe what can happen when ocean waves churn up water and oil from an oil spill.

Learners cut out pictures of continents and attempt to put them together to form Pangaea, the supercontinent present on the Earth approximately 300 million years ago.

In this three-part activity, learners play a game and conduct two simple experiments to explore water and surface tension. Learners will have fun discovering how water "sticks" together.

In some parts of the world, lakes freeze during winter. In this activity learners will explore water’s unique properties of freezing and melting, and how these relate to density and temperature.

In this activity, learners make edible T. rex teeth (with adult assistance). The treat is a white and dark chocolate covered banana on a stick.

Learners test two jars containing hot water, one covered with plastic and one open, for changes in temperature.

In this activity about water solubility and density, learners use critical thinking skills to determine why water can dissolve some things and not others.

In this activity (on page 8), learners model how marble statues and buildings are affected by acid rain.

In this activity, learners use raisins and seltzer water to understand why waves don’t move objects forward. Learners conduct two simple experiments to understand the circular movement of waves.

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

In this activity, learners explore Boyle's Law and discover that water will boil at room temperature if its pressure is lowered.

Lakes, streams and other freshwater bodies are a habitat for lots of living things, big and small.

Use this model to demonstrate the goal of NASA's Kepler Mission: to find extrasolar planets through the transit method.

In this activity, learners will measure the length of a shadow and use the distance from the equator to calculate the circumference of the earth.

In this activity about problem-solving, learners build a house for the Three Little Pigs using twenty straws and two index cards.

In this activity, learners will pretend to be archaeologist using this chilling experience.

In this activity, learners test how cornstarch and glitter in water move when disturbed. Learners compare their observations with videos of Jupiter's and Earth's storm movements.

In this activity, learners use a simple 3D model to discover why the Moon has phases.

In this activity, learners will investigate how craters are made and the different factors that contribute to size left from the impact.

In this activity, learners model ancient lunar impacts using water balloons.
