In this demonstration/experiment, learners discover that different colors and materials (metals, fabrics, paints) radiate different amounts of energy and therefore, cool at different rates.

In this activity, learners construct an indoors obstacle course and discover how using an eye patch can help them complete the course in the dark.

In this activity, learners create a mixture of water, alcohol and permanent marker ink, and then add salt to form a colored alcohol layer on top of a colorless water layer.

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

In this activity about depth perception, learners create an optical illusion in a shoe box.

This lesson familiarizes learners with the term "tropical belt." First, learners locate the equator, Tropic of Cancer and Tropic of Capricorn on a map and trace these lines with a crayon.

In this hands-on activity, learners use the steps of the design process to create a hook to rescue a "space capsule" from the water.

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

This activity (on pages 10-12 of the PDF) encourages learners to consider what makes living things different from non-living things.

In this demonstration, learners explore a variation of a Foucault pendulum, but upside down.

In this chemistry demonstration, acid rain is simulated in a petri dish.

In this activity, learners make a model of a beehive using simple materials.

In this activity about the relationship between food and energy (page 5 of PDF), learners conduct an experiment to compare how much energy is released as heat from two different foods.

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

Students design and build their own parachutes in this hands-on engineering project.

In this hands-on activity, learners will become familiar with the special adaptations of rainforest plants and discover the conditions needed for tropical trees to survive along with what can impinge

In this math lesson, learners explore probability.

In this optics activity, learners explore diffraction by adding wax blocks to a ripple tank. The wedge-shaped blocks act as obstacles that the wave must bend around.

In this activity about potential and kinetic energy, learners get to roll a can across the floor and then watch it roll back to them as if by magic. This activity is always great for looks of wonder!

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.
