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

Did you know that the water we use today is the same water found on Earth millions of years ago? The Earth constantly uses and recycles water in a process called the water cycle.

This activity offers learners and their families several ways to raise their awareness together about home water.

In this water pollution activity, learners create pond water cultures and investigate the effects of adding chemicals or natural nutrients.

Learners work in teams to design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy.

In this easy chemistry activity, learners submerge pennies in different liquids (water, lemon juice, vinegar, liquid hand soap, salt water, and baking soda mixed with water) to observe which best clea

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

In this activity, learners discuss the different salinities of oceans, rivers and estuaries.

Learners build models to learn about the special cells and structures that plants use to move water from their roots up through the stems and leaves.

In this activity, learners create a freshwater ecosystem in a large plastic bottle. Learners cut and prepare bottles, then fill with water, aquatic plants, snails and fish.

In this activity, learners investigate the different salinity levels of oceans, rivers and estuaries.

In this environmental science activity (page 3 of the PDF), leaners will identify and explain the causes of erosion.

In this chemistry activity (page 3 of the PDF), learners will learn about crystals by growing their very own.

In this activity, learners build a model of a self-sustaining habitat (growing grass and beans from seeds).

In this activity (located at the bottom of the page), learners investigate soil and explore the creatures that live in it.

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

In this activity, learners are introduced to challenges of maintaining temperatures while living in space.
