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.

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.

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

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 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.
