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

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

During this interactive "survival" game, students learn about the importance of camouflage and how it helps animals to blend into their surroundings, as either predator or prey.

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

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

In this activity, learners explore what is and is not active play and how it contributes to a healthy body and mind. Making active play a routine part of every day is a key concept of the experience.

In this activity about combustion and energy, learners observe a burning candle in a sealed jar and the burning of white sugar.

In this outdoor activity and game, learners explore how animals adapt for survival through coloration, markings and camouflage.

This laboratory exercise is designed to show learners how DNA can easily be extracted from lima bean bacteria. This experiment requires the use of a centrifuge (not included in cost of materials).

In this activity, learners mix milk, vinegar, baking soda, and water to create sticky glue. Use this activity to explain how engineers develop and evaluate new materials and products.

This activity uses Jell-O(R) to introduce learners to microfluidics, the flow of fluids through microscopic channels.
