In this chemistry demonstration, learners will discover that phenolphthalein is a chemical that displays different colors depending on the acidity or basicity of the environment.

Learners are given mysterious white powders and have to determine their identity with chemical tests.

Learners mix a solution containing luminol and copper with a fake blood solution. A chemical reaction between the luminol solution and fake blood (hydrogen peroxide) show learners a blue glow.

This activity is about collecting and analyzing DNA as part of a criminal investigation.

In this activity, learners simulate the process of DNA fingerprinting by using electricity to separate colored dyes.

With a coffee filter, a black marker, and a cup of water, discover the secret colors hidden in black ink.

In this activity, learners explore acid and bases as they create their own invisible ink out of baking soda and grape juice.

In this activity, learners perform a simulated blood test procedure.

In this activity, learners extract DNA from their own cheek cells, then create a rudimentary DNA profile similar to those seen on crime scene dramas.

Learners analyze mixtures of dyes using filter paper chromatography. They place spots of the different dyes at the bottom of a piece of filter paper, and hang the paper to touch the surface of water.

In this activity, learners create a necklace of wheat germ DNA. Learners add alcohol to wheat germ so that the DNA clumps together.

Learners press their fingertip onto a clean Plexiglas sheet. The fingerprints are then revealed as learners dust over the print with fingerprint powder.

Learners observe different paper samples under ordinary room light and under a black light to learn some of the chemical differences between different types of paper.
