In this activity, learners make a miniature greenhouse or "terrarium" to explore the greenhouse effect.

In this activity, learners explore the different heating properties of soil and water.

In this earth science activity, learners conduct a series of short experiments to explore how rocks change.

In this activity, learners design and build a simple wind vane —one of the oldest kinds of weather tools— and use it to show wind direction.

In this activity, learners explore in what ways the shape of the land and the pull of gravity influence how water moves over Earth.

In this activity, learners simulate the energy transfer between the earth and space by using the light from a desk lamp desk lamp with an incandescent bulb and a stack of glass plates.

In this outdoor activity/game, learners use thermometers to simulate how lizards survive in habitats with extreme temperatures.

In this activity, learners create a biosphere in a baggie.

In this sunny day experiment, learners measure and compare how quickly light and dark colored materials absorb heat.

In this online activity, learners see simulations of how processes shape the Earth, and see estimates of how long these processes take.

This activity demonstrates liquefaction, the process by which some soils lose their solidity during an earthquake.

In this activity (page 13 of the PDF), learners discover how weathering and erosion change the Earth’s surface.

In this experiment, learners use a blow dryer and water bottle to observe and record changes in air pressure caused by changes in temperature.

In this activity, learners construct models of plants that are adapted to living under specific environmental conditions.

Why is ocean water sometimes the warmest when the average daily air temperature starts to drop? In this activity, learners explore the differing heat capacities of water and air using real data.

In this activity, learners will simulate the processes of the water cycle at home in a plastic sandwich bag.

When it rains, water can collect on top of and seep into the ground. Water can also run downhill, carrying soil and pollution with it.

In this outdoor activity, learners plan a simple foot path and create an environmental impact study of the natural area where the path would be.

In this group activity, learners consider environmental conditions—temperature, presence of water, atmosphere, sunlight, and chemical composition—on planets and moons in our solar system to determine

"Exploring the Solar System: Hide and Seek Moon" is an engaging way for early childhood learners to experiment with some of the tools scientists use to study objects that are very, very far away, and
