How do dams support bodies of water? Scholars engage in a hands-on STEM activity where they design, build, and test dams to learn about bodies of water and how humans use natural resources. They learn how criteria and constraints affect...

High schoolers observe how a cell uses an enzyme to rid itself of a poisonous substance by experimenting with hydrogen peroxide, potatoes, liver and carrots. They record the temperature and changes of the hydrogen peroxide as other...

Enzymes in our bodies each have a job to do. Learn the factors that affect the activity of some enzymes using the third activity of an informative 12-part biology series. A three-part laboratory activity asks teams to investigate how...

Science learners simulate what happens when ice breaks up and floats on water and how increased pressure on ice causes it to melt faster. They view a clip from the movie, The Day After Tomorrow, and relate their lab activities to what...

Eighth graders discuss the forms of heat transfer that relate to the human body. Discussion revolves around the ability of different designs of hats to change the rate of heat transfer to and from the body. Students then experiment...

Ninth graders conduct research on the subject of sea water. They use a variety of resources to obtain information. There are helpful resource links listed in the lesson plan. In conjunction with the research students make inquiry of the...

Sprouting scientists explore the concept of density by making mass and volume measurements for five different liquids. From these measurements, they calculate densities. They apply their learning to explain Galileo's thermometer works...
