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

DNA is the thread of life. Encoded in its genetic sequence is the information that makes each of us unique. This activity allows you to see long, stringy strands of DNA extracted from wheat germ.

In this chemistry demonstration, acid rain is simulated in a petri dish.

In this experiment, learners will explore whether increased carbon dioxide makes our oceans more basic or more acidic.

In this activity, learners explore how environmental engineers might approach solving the problem of an oil spill.

In this chemistry challenge, learners systematically investigate which combination of four solutions produces a deep red color.

In this activity, learners discover that atoms and ions of different metals will change places.

In this activity, learners of all ages can become food scientists by experimenting with flour and water to make basic pasta.

In this activity, learners mix ingredients in a plastic bag, and then identify three characteristics of a chemical reaction: production of heat, color change, and production of a gas.

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).
