In this activity, learners heat and cool carbonated water to find out whether temperature has an effect on how fast the dissolved gas leaves carbonated water.

In this activity about human anatomy (page 20 of PDF), learners investigate the structure of muscles by comparing yarn and cooked meat.

In this activity, learners make colored sugar and add it to water, alcohol, and oil to discover some interesting differences in dissolving.

In this activity (located on page 5 of PDF), learners work in groups to create dig sites for display.

In this bilingual (English/Spanish) activity, learners create family trees by tracing the hands of their family members.

In this activity, learners transform everyday milk into small plastic figurines and jewelry. Use this activity to introduce learners to monomers and polymers.

In this quick activity, learners observe how the added sugar in a can of soda affects its density and thus, its ability to float in water.

Learners are challenged to discover the relative densities of colored liquids to create a rainbow pattern in a test tube.

In this electrochemistry activity, young learners and adult helpers create a battery from a potato to run a clock.

In this chemistry demonstration, learners investigate the rule "likes dissolve likes" by combining three, immiscible liquids to create a colorful density column.

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 outdoor activity, learners investigate spider webs and feeding behavior, particularly how spiders trap food in their sticky silk webs while not getting stuck themselves.

In this demonstration about momentum, use physics to distinguish between a hard-boiled egg and a raw egg without cracking them open.

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

In this activity, learners will develop a method to test five similar-looking powders (baking soda, baking powder, cream of tartar, detergent, and cornstarch) with four test liquids (water, vinegar, i

Learners design their own experiment to determine which M&M color dissolves the fastest in water.

In this activity, learners use things from the kitchen as building materials to explore how shapes contribute to the strength of different structures.

In this chemistry activity, learners use the lowered freezing point of water to chill another mixture (ice cream) to the solid state.

In this introductory activity and demonstration, learners are introduced to the concept that different substances react chemically in characteristic ways.

This activity about density provides instructions for making a miniature "lava lite" with just salt, oil, water, and food coloring.
