In this activity, learners experiment with creating various types of bubble solutions and testing which ingredients form longer-lasting bubbles.

In this activity, learners explore how objects can have positive, negative, or neutral charges, which attract, repel and move between objects.

In this activity, learners get hands-on experience with ratios and scaling while making their own jewelry out of recycled plastic containers.

In this activity, learners explore the relationship between electric charges and magnetic fields.

In this activity, learners explore sublimation by conducting experiments with dry ice.

In this classic hands-on activity, learners estimate the length of a molecule by floating a fatty acid (oleic acid) on water.

In this activity, learners will design a way to identify a powder found at a crime scene by comparing it with known powders, with the goal of solving a crime.

In this group activity, learners act out key stages of the "ocean carbon cycle" (also known as the "carbonate buffer system") through motions, rearranging blocks and team tasks.

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.

In this activity, learners create a mixture of water, alcohol and permanent marker ink, and then add salt to form a colored alcohol layer on top of a colorless water layer.

In this activity (on page 1), learners role play as atoms to explore how atoms can be rearranged to make different materials.

In this activity (page 10), learners explore how molecules self-assemble according to forces of attraction and repulsion.

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

In this activity learners explore surface tension. Why are certain objects able to float on the surface of water and how do detergents break the surface tension of water?

In this activity, learners investigate the basic crystal structures that metal atoms form.

In this activity, learners prepare four polymer elastomers and then compare their physical properties, such as texture, color, volume, density, and bounce height.

In this activity (page 12), learners explore how molecules self-assemble and how molecules must fit together, like a lock and key, in order to identify each other and initiate a new function as a comb

In this activity, learners build a simple electrolysis device. Then learners use an indicating solution to visualize hydrogen and oxygen molecules in water.

In this activity, learners identify different plastics in a mystery bag. Learners discover that plastics are classified #1 through #7.

In this activity, learners investigate convection by using food coloring and water of different temperatures.
