In this great hands-on activity, learners use patterns to make a teepee from newspaper that they sit inside.

In this engineering activity, learners build a device (an anemometer) to measure how fast the wind is blowing.

In this activity, learners explore the human influences on the carbon cycle and examine how fossil fuels release carbon.

In this ocean engineering activity, learners explore buoyancy and water displacement. Then, learners design models of deep sea divers that are neutrally buoyant.

In this activity, learners conduct three experiments to examine temperature, the different stages of the water cycle, and how convection creates wind.

In this activity, learners construct a traditional handicraft toy that illustrates a motion commonly associated with violins and earthquakes.

In this activity, learners build penetrometers to test leaf toughness. Biologists measure leaf toughness to study the feeding preferences of insects and bugs.

In this activity, learners are invited to imagine the park of their dreams!

Through discussion and hands-on experimentation, learners examine the geological (ancient) carbon cycle.

In this activity, learners identify different plastics in a mystery bag. Learners discover that plastics are classified #1 through #7.

In this activity, learners discover why only some types of plastic can be recycled.

This board game teaches learners about energy decision making. Players select cards that determine the transportation and home design that will influence their expenses as they play.

In this outdoor water activity, learners explore how to change the direction of water flow. Learners make puddles in dirt or use existing puddles and sticks to make water flow.

Learners develop an understanding of air pressure in two different activities.

In this activity, learners use the Sun's energy to cook marshmallows. Learners construct the solar oven out of simple everyday materials.
