Learners conduct a simple experiment to model and explore the harmful effects of acid rain (vinegar) on living (green leaf and eggshell) and non-living (paper clip) objects.

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.

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.

Learners blow into balloons and collect their breath--carbon dioxide gas (CO2). They then blow the CO2 from the balloon into a solution of acid-base indicator.

Learners make their own acid-base indicator from red cabbage. They use this indicator to test substances around the house.

Create gas with a glass of water, some wire, conductors and a battery! You will be separating water (H2O) into oxygen and hydrogen.

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.

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 demonstration, learners compare and contrast regular water ice to dry ice (frozen carbon dioxide). Both samples are placed in a solution of acid-base indicator.

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.

In this activity, learners test exhaled breath for carbon dioxide and learn how to use an indicator as a simple way to measure pH.

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 field study, learners discover how to collect data in the field and how their efforts can help certain animals, specifically, amphibians.

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.

"What's in the Water" lets participants use tools to solve the mystery- what chemicals and compounds are in a sample of water?

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.
