Chameleons

Super scientists visit ten stations to predict, observe, and draw conclusions about the physical and chemical changes that occur when different states of matter—liquid, solid, and gas—are placed under a variety of conditions. To...

Young scientists investigate chemical and physical changes to the states of matter—gas, liquid, and solid—as well as solutions and suspensions with a variety of demonstrations, grand conversation, and an interactive quiz to check for...

Here is part two of a two-part lesson in which scholars investigate the changing states of water—liquid, solid, and gas—and how energy from heat changes its molecules. With grand conversation, two demonstrations, and one hands-on...

Find out how much your earth scientists learned about the atmosphere in the unit on global atmospheric change with this assessment. After writing a letter to persuade others to make changes to protect our atmosphere, pupils take the same...

If you have taught the first lesson in this mini unit, learners already know that cabbage juice and vinegar cause chemical changes in some materials. Now, they get a chance to use them to compare the liquids' reactions to five known and...

Young scientists transform themselves into rivers, oceans, clouds, and drops of water in order to explore the water cycle. After assigning and explaining to students their different roles in the activity, the teacher reads aloud a...

What affects might an ecosystem undergo if the climate changes? This is the focus of a video that describes how a tiny change in an ecosystem can "throw everything off."

What happens to organisms when the environment around them changes? This is the focus of a video that describes how living things must adapt to their ever-changing environment.

How do living things change their environment? This is the focus of a video that describes how the building of communities and clearing of forests changes the types of living organisms that can thrive there.

Build a strong foundation for your teaching of stability and change! The video addresses the Next Generation Science Standards Cross-Cutting Concept through insightful examples. The narrator includes ideas for introducing the standard in...
