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

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.

In this activity, learners "draw" with frozen tempera paint. The ice cubes are prepared the day before by placing watered down tempera paint and popsicle sticks in ice cube trays.

Learners experiment with a commercially available liquid-crystal coaster. They warm the material with their hands for varying lengths of time and observe the changing colors that result.

In this activity, learners explore temperature changes from chemical reactions by mixing urea with water in one flask and mixing calcium chloride with water in another flask.

Learners use a commercially available toy to experiment with density. They fill a chamber in the toy submarine with baking powder and release it into a tank of water.

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

Learners explore how recyclers take advantage of the different properties of materials, such as magnetism and density, to separate them from a mixture.

Learners design, build, and test models of "dragon boats" made from up to three milk cartons.

As a group, learners investigate three packages which are all the same size and shape, but have different contents. One is filled with foam, one is filled with wood, and one is filled with metal.
