In this activity on page 8 of the PDF (Behind the Scenes with Chemistry), learners make three of Harry Potter's essential school supplies: quills, ink, and color-changing paper.

In this chemistry activity, learners make indicator solution from red cabbage. Then, learners test everyday foods and household substances using the cabbage juice indicator.

In this online interactive simulation, learners will test the pH of liquids like coffee, spit, and soap to determine whether each is acidic, basic, or neutral.

Learners add acid rain (nitric acid) to two cups that represent lakes. One cup contains limestone gravel and the other contains granite gravel.

In this chemistry meets cooking activity, learners compare the stability of egg white foams with various additives.

In a series of three experiments, learners explore the basics of biotechnology using self-locking plastic baggies. Each experiment demonstrates a phenomenon or principle of biotechnology.

Ocean acidification is a big issue due to the amount of carbon dioxide humans release. CO2 in the atmosphere is absorbed into the ocean thus changing its acidity.

What is the optimal environment for hatching brine shrimp? Using a scaffold, learners design and conduct experiments testing the effect of a single abiotic factor on brine shrimp cyst hatch rate.

A group of learners simulates the spread of disease by trading slips of paper, one set of which has been treated with a baking soda solution.

In this chemistry activity (page 5 of the PDF), learners make an acid-base indicator using cabbage. Learners then explore how various subtances react with this indicator.

In this activity, Frankenstein's lab is running out of electricity! Learners use fruit to help Igor find a temporary source of energy to turn on a light.

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

Learners take a field trip along a local body of water and conduct a visual survey to discover information about local land use and water quality.
