In this activity, learners use rice grains to model the composition of the atmosphere of the Earth today and in 1880. Learners assemble the model while measuring percentages.

In this activity, learners make different shapes that hold exactly one mole of gas (air).

In this activity, learners create a model using metric measuring tapes and atmosphere composition data.

In this activity, learners will make their own prism and use a glass of water to separate sunlight into different colors.

In this classic hands-on activity, learners estimate the length of a molecule by floating a fatty acid (oleic acid) on water.

In this outdoor activity, learners discover how the environment around a building affects the growth of plants.

In this activity, learners explore the devices used over time to measure changes in temperature.

In this activity, learners will explore how the human brain interprets environmental stimuli.

In this activity, learners cut wells in JELL-O© and load the wells with different detergent solutions.

In this activity, learners make their own Sun tracker to explore how ancient civilizations around the world studied the Sun.

In this experiment, learners construct an equilateral triangle using graph paper, a pencil, protractor and ruler. They also make a "laser triangle" using a laser pointer and front-silvered mirrors.

In this activity, learners use simple items to construct a device for indicating air pressure changes.

Learners build a filter from old soda bottles and dirt. They create polluted water, and pour it through their filter to clean it.
