In this activity, learners will model the mechanical weathering and erosion of rocks in a stream or river.

This is a series of demonstrations about different electrical and magnetic phenomena.

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

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 work in groups to construct bridges using stale marshmallows and toothpicks.

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

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

Learners build models to learn about the special cells and structures that plants use to move water from their roots up through the stems and leaves.

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.

This is an activity exploring color and color mixing.

In this activity (on pages 11-14 of PDF), learners cut out pictures from magazines of foods that help make bones strong and glue the pictures to a paper bone.

Learners work in pairs to design, construct, and test a device that exhibits positive, neutral, and negative buoyancy. They test a number of different objects in water to see if they sink or float.

Learners build models of sinkholes to gain an intuitive knowledge of their physical aspects.

This activity (on pages 21-32 of PDF) has learners act out several classic brain teasers.

In this activity, leaners explore building techniques by recreating the story of The Three Little Pigs.

In this activity, a group of learners work collaboratively to design and construct a paper model showing the evolution of an environment through multiple stages, from prehistory through the modern cit

In this activity, learners become detectives and use chemistry to investigate fingerprints.

In this activity, learners add dilute bleach solution to water that has been dyed with yellow, blue, and green food color.
