In this activity, learners examine fingerprints. Learners leave a hidden print on a surface and then make their own print detecting powder from graphite (found in pencils).

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.

Learners smell balloons filled with different scents to guess what's inside. From this, they infer the presence and motion of scented molecules.

In this activity (described on pages 39-42 of PDF), learners make a paper wheel (on pages 57-60 of PDF) that shows them the relative loudness of different sounds.

In this activity (on pages 25-32 of PDF), learners make models of the inner ear out of pipe cleaners.

Learners use a simple process to extract DNA from strawberries.

Learners mix a solution of luminol with hydrogen peroxide to produce a reaction that gives off blue light.

Learners design their own experiment to investigate how pollution diffuses through ground material.

Learners add acid rain (nitric acid) to two cups that represent lakes. One cup contains limestone gravel and the other contains granite gravel.

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

In this two-part activity, learners will extract their own DNA from their cheek cells and learn how DNA is analyzed and used to solve crimes.

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

This lesson gives full instructions for making cabbage juice indicator, a procedure sheet for learners to record observations as they use the indicator to test materials, and extension activities to d

In this activity (on pages 25-31 of PDF), learners soak sponges with different amounts of plaster of paris to simulate different levels of calcification in bone formation.

In this activity, early learners create paintings by making music and rhythm. Learners place paper in cans, add paint-soaked beans (or pebbles) and put the tops on.

In this activity (on pages 19-24 of PDF), learners soak chicken bones or eggshells in vinegar for several days.

In this activity, learners explore light, color and rainbows by making their own rainbow glasses.

In this activity, learners investigate vitamin C.
