Learners will explore the scientific mystery behind a disappearing group of trees by examining data and attempting to explain the decline.

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.

In this activity, learners separate the protein from milk and and use it to make their own glue.

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

Learners add drops of alginate solution to a solution of calcium chloride. The alginate does not mix with the calcium chloride, but forms soft gel beads.

In this experiment, learners design and build a model room in a shoebox and furnish it with tiny furniture.

In this activity, learners combine two substances (plaster of Paris and water) to make a cast of an object's imprint in clay.

This activity (on page 2 of the PDF) features a recipe to create the stretchy polymer Flubber from Borax detergent, white glue, and water.

Learners use filter paper and water to analyze six different markers. They mark the paper with ink, and dip the paper in water. The water travels up the paper and dissolved ink travels with it.

This game plays a dozen different sounds, altered to simulate what they would sound like if you had hearing loss.
