Learners design their own experiment to investigate whether the temperature of the surrounding water affects the rate at which the colored coating dissolves from an M&M.

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

This laboratory exercise is designed to show learners how DNA can easily be extracted from wheat germ using simple materials.

In this activity about water solubility and density, learners use critical thinking skills to determine why water can dissolve some things and not others.

In this activity, learners investigate whether having sugar already dissolved in water affects the speed of dissolving and the movement of sugar and color through the water.

This laboratory exercise is designed to show learners how DNA can easily be extracted from onion cells using simple materials.

In this environmental health activity, learners grow and observe bread mold and other kinds of common fungi over the course of 3-7 days.

Learners carefully pour vegetable oil, water, and corn syrup in any order into a cup and discover that regardless of the order they are poured, the liquids arrange themselves in layers the same way.

This laboratory exercise is designed to show learners how DNA can be extracted from a chunk of thymus (sweetbread) or liver.

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

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.

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

In this "Sid the Science Kid" activity from Episode 109: The Perfect Pancake, learners make applesauce to explore irreversible change.

In this activity, learners design a crushing test and discover that identifying and controlling the variables may be difficult.

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 explore dinosaur fossils by making an edible treat. First, learners read "Dinosaur Bones" by Aliki to examine how fossils are formed.

In this lab exercise, learners explore diffusion, cell membranes and particle size using beets and three alcohols.

In this activity, learners compare and contrast their own skin (including the area covered) with that of an orange.

In this hands-on experiment, kids use chemistry to explore whether acids or bases are better at restoring a penny’s shine.
