This is an activity in which learners create magic wands from a variety of materials making their choices by considering what kind of magic they want to make.

This activity is on page 3 (continued on page 2) of the pdf, part of the Simple Machines Discovery Box. In this fun activity, learners "create" a complex machine by simulating the parts in action.

Learners compare the properties of two balls that appear identical. One ball bounces, while the other ball "thuds." The “bounce” ball is made of the polymer polybutadiene (-C4H4-).

In this chemistry lab activity, learners model the colors of fireworks by burning metallic solutions in a flame and observing the different colors produced.

In this activity, learners explore polymer structure and their ability to reform around objects by attempting to stab a wooden skewer through a balloon without popping it.

In this design challenge, leaners attempt to build a strong structure out of LEGO® bricks that can withstand a 4-foot drop.

Learners place their hands on different metals and use an ammeter to monitor the flow of electricity from one metal to another.

In this activity (on page 2 of PDF), learners make their own totem poles out of recycled materials.

Learners observe working lava lamps to understand how they work (included in PDF link).

In this activity, learners will design a way to identify a powder found at a crime scene by comparing it with known powders, with the goal of solving a crime.

In this tabletop activity (on pages 32-40), learners make Möbius strips -- 3D surfaces with only one side.

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.

Learners observe two joined glass tubes containing a conductive salt solution. Electrodes are passing an electric current through the water.

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.

Eggs are placed in vinegar for one or two days to dissolve the shells. Then, learners place the eggs in water or corn syrup and observe them over a period of days.

Learners experiment with a commercial photo-sensitive paper (Sunprint® or NaturePrint® paper). They place opaque and clear objects on the paper and expose it to bright light, observing the results.

Learners use a simple process to extract DNA from strawberries.
