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

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

In this matchmaking activity (on page 2 of the PDF under GPS: Animal Scent Activity), learners will each have a scented cotton ball taped to their shoulder. The scent (e.g.

In this activity, learners investigate carbon sequestration by creating a carbonated beverage out of apple juice and dry ice.

In this activity, learners separate the components of Gatorade using a home-made affinity column.

In this chemistry meets cooking activity, learners make carbonated, vanilla ice cream using dry ice and denatured ethanol, which are both inexpensive and accessible.

In this activity, learners use sets of cards to assign microorganisms to different groups.

In this activity, learners measure the amount of carbon dioxide in a carbonated drink.

In this activity related to plant biotechnology, learners extract DNA from fruit to investigate how it looks and feels.

In this activity (on pages 34-39), learners make a fairly detailed model of DNA using licorice and gumdrops.

In this simple chemistry activity (page 1 of PDF under SciGirls Activity: Colorblind Dogs) about acids and bases, learners will mix a baking soda and water solution and use it to paint a message on a

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 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

In this math lesson, learners explore the relationship between the thickness of a spaghetti bridge, the length of the bridge, and the amount of weight that can be supported by the bridge.

In this math lesson, learners apply the concepts of ratios and percentages to the distribution of letters contained in a box of Alphabits® cereal.

To convey the concept of how animals adapt to survive, this game asks learners to imagine what adaptations a given animal would need to live in a certain environment—including environments where such

In this activity on page 8 of the PDF, learners investigate vitamin C. Learners conduct a chemistry experiment to determine if Tang drink mix or orange juice contains more vitamin C.

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 tasty activity, learners make their own ice cream any day of the year in an exploration of heat and cold. Highlights include freezing and melting and the transition from liquid to solid.

In this activity, learners use the Sun's energy to cook marshmallows. Learners construct the solar oven out of simple everyday materials.
