In this easy chemistry activity, learners submerge pennies in different liquids (water, lemon juice, vinegar, liquid hand soap, salt water, and baking soda mixed with water) to observe which best clea

Learners will compare the growth rate and appearance of crystals forming on small rocks to those growing on miscellaneous objects. Learners will also investigate how temperature (warm vs.

This is an activity (located on page 3 of PDF under Hockey Sticks Activity) about composites, materials made of 2 or more different components.

This activity (on page 2 of the PDF under SciGirls Activity: Hovercraft) is a full inquiry investigation into hovercraft engineering and design optimization.

In this activity, learners explore chemistry and the microbial world by making their own sourdough starter and bread at home using only flour and water.

This lab activity is about toxic substances like pesticides and their effects on biological systems. The activity starts with an introduction of how birds sequester calcium to make an egg.

In this chemistry activity, learners explore the amount of copper in a new penny. Learners use toilet bowl cleaner to hollow out the interior of a penny with zinc inside.

In this activity related to plant biotechnology, learners transform a strain of E. coli using green fluorescent protein from a bioluminescent jellies.

In this combination chemistry and physics activity, learners explore water absorption in dried beans or peas and learn how this affects their physical properties.

In this activity, learners calculate the percentage of oxygen in the atmosphere by using steel wool's ability to rust.

Eggs are placed in vinegar for one or two days to dissolve the shells. Then, learners place the eggs in water or corn syrup and observe them over a period of days.

In this activity (page 2 of PDF under GPS: Garbology Activity), learners will prepare sheets of homemade recycled paper from several different source pulps.

In this highly collaborative activity, learners design and complete a controlled experiment which attempts to answer a simple question about the slime mold Physarum.

Using zebra mussels (Dreissena polymorpha), elodea and an indicator dye, learners study the role of light in photosynthesis.

In this kitchen chemistry activity, learners explore the chemistry of crystals by making sugar crystals, consider a common chemical reaction type responsible for the rising of muffins and cake in the

In this activity, learners make a miniature greenhouse or "terrarium" to explore the greenhouse effect.

In this activity, learners conduct a series of hands-on experiments that demonstrate how the working of plants' veins, known as capillary action, enables water to travel throughout the length of a pla

In this activity about daily rhythms (on page 17 of the PDF), learners will explore circadian patterns in humans, animals and plants.

This is an activity (located on page 3 of the PDF under Nanosilver Activity) about diffusion of small molecules across cell membranes.

In this activity, learners investigate the movement of water into and out of a polymer. Learners test the diffusion of water through gummy bears, which are made of sugar and gelatin (a polymer).
