In this activity, learners explore the different salinities of various sources of water by taste-testing.

In this demonstration, learners observe the effects of density and pressure. A "diver" constructed out of a piece of straw and Blu-Tack will bob inside a bottle filled with water.

In this activity, learners explore how salt water freezes in comparison to fresh water.

In this activity, learners discover if carbon dioxide has an effect on temperature.

In this quick and easy activity and/or demonstration, learners use two empty 2-liter bottles and hot tap water to illustrate the effect of heat on pressure.

In this quick activity/demonstration about density, learners examine what happens when two cans of root beer--one diet and one regular--are placed in a large container of water.

In this activity, learners explore the concept of permeability to better understand why amphibians are extremely sensitive to pollution.

In this activity, learners explore deoxyribonucleic acid (DNA), a nanoscale structure that occurs in nature.

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

In this optics activity, learners discover how they can make glass objects "disappear." Learners submerge glass objects like stirring rods into a beaker of Wesson™ oil to explore how the principles of

Learners observe the outside and inside of raw chicken eggs, record descriptions, and hypothesize what will happen when a facilitator drops an egg on the floor.

In this activity (2nd activity on the page), learners explore how the nose is responsible for part of the flavor we taste in food.

In this activity, learners create a water prism to break light into the seven colors of the rainbow.

In this activity, learners explore how their depth perception would be affected if they only had one eye. Learners work in pairs and attempt to drop a penny in a cup with one eye covered.

In this activity, learners explore how light and dark colored objects absorb the Sun's radiations at different rates.

In this easy demonstration (3rd on the page), learners explore depth perception by conducting a test with two pencils.

In this quick activity/demonstration (5th on the page), learners explore depth perception.

In this activity, learners use chocolate to explore how the Sun transfers heat to the Earth through radiation.

This activity demonstrates the importance of wearing a helmet to protect the brain. An egg is used to symbolize a head with the shell as the skull and the inside of the egg as the brain.

In this activity, learners try to blow up a balloon hanging inside of an empty bottle.
