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

Use a homemade potato launcher to explore air pressure. This activity includes simple instructions on how to build a homemade propulsion pipe using pipe, a wooden dowel and duct tape.

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

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 use objects they find on a nature and water to make creative frozen sculptures.

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

In the wild, small crustaceans known as brine shrimp live in marine habitats such as saltwater lakes.

Water treatment on a large scale enables the supply of clean drinking water to communities.

In this activity, learners investigate the movement caused by dispersion. Learners discover that dispersion is the random movement of objects.

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.

This activity gives caregivers and their children an opportunity to practice scientific ways of thinking that are developmentally appropriate for early learners.

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

In this quick activity (on page 2 of the PDF under GPS: Body Electricity Activity), learners will observe how dry breakfast cereal appears to dance when it gets close to a balloon charged with static

"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

In this activity, learners will test cups full of potting soil, sand, and sphagnum moss to see which earth material is able to soak up the most water.

Water on Earth is in lakes, the ocean, rivers, underground, and frozen glaciers.

This is an activity about turbidity, or the amount of sediment suspended in water.

Learners investigate why the Sun and Moon appear the same size in the sky even though the Sun is over 400 times larger in diameter.

In this outdoor activity, learners explore UV rays from the Sun and ways to protect against these potentially harmful rays.
