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 experiment with a 2-liter plastic bottle containing water and four “divers." The divers consist of open, transparent containers with the opening points downward.

In this activity (on pages 41-47 of PDF), learners explore tesselating geometric patterns (repeated shapes, similar to the art of M.C. Escher).

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.

This lesson (on pages 46-55 of PDF) features two strategy board games -- one from Ghana and one from China. The first game, Achi, is a cross between checkers and tic-tac-toe.

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

The popular sudoku puzzles use numbers, but the game could played with any set of 9 different objects!

Learners make a simple battery out of "sandwiches" of aluminum foil, pennies, and a salt water-soaked paper towel.

Learners use a simple process to extract DNA from strawberries.

Learners observe a sealed container holding a clear colorless liquid. They shake the container and the fluid turns blue. When allowed to sit for a few moments, the fluid turns colorless again.

This activity explores the basic workings of a siphon, which is the core technology that makes toilets work.

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

Learners add two dyes to mineral oil and water, and then compare their miscibility (how well they mix) in each.

In this classic memory game (on pages 37-45 of PDF), learners turn over tiles to reveal images on the back.

Learners explore the Bernoulli effect by building an airfoil (airplane wing) and making it fly.

In this activity (on pages 49-54 of PDF), learners play with tangrams, a set of triangles, squares and a parallelogram that can combine into a larger square as well as all sorts of other shapes.

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

In this activity, learners discover that there is space between molecules even in a cup "full" of water. They first fill a cup with marbles, and then add sand to fill the gaps between the marbles.

Learners design different shaped bandages for different purposes. First, they draw their designs on paper.
