Learners are challenged to discover the relative densities of colored liquids to create a rainbow pattern in a test tube.

In this chemistry challenge, learners identify which plants have the enzyme "catalase" that breaks hydrogen peroxide into water and oxygen.

In this activity, learners test what happens when they put baking power on different frozen liquids.

In this chemistry challenge, learners work to figure out which of four juices are real, and which is just food coloring and sugar.

In this activity, learners explore acids and bases by preparing six solutions that combine vinegar and ammonia, ranging from acid (all vinegar) to base (all ammonia).

In this experiment, learners will conduct chemical and physical tests to identify mystery substances.

During this activity, learners will make different versions of "ooze" using varied proportions of detergent and glue.

The "Rocket Reactions" activity is an exciting way to learn about how materials interact, behave, and change.

In this activity, learners will create their own bubble solution. Learners will explore chemistry, geometry and trial and error through this activity.

Many of the genetic sequences found in the fruit fly genome are similar to those found in humans.
