Students learn about the water treatment process as they complete a digital “escape room” on a Google site.

This week's episodes and hands-on activity explore some cool chemistry!

Mussels are a kind of invertebrate that filter food out of the water they live in. This makes them a great tool for monitoring environmental water quality and tracking bioaccumulation in aquatic food webs.

Carbon dioxide is an important part of the air on Earth and in space. What is carbon dioxide? How is it measured? How can it affect us mentally and physically?

Has your fresh juicy apple turned an unsightly brown? Learn about the redox reaction behind the transformation.

Acid rain is any precipitation that has an unusually low pH. It can be rain, snow, fog, etc. But what is a low pH and why is this a problem?

What are your teeth made up of? What chemistry is at work in your mouth? Why do some people get cavities even if they brush regularly?

Oceans absorb the greatest amount of solar radiation on Earth. Ocean warming can lead to glaciers melting and ocean acidification.

It starts with curds and whey! Explore the basic chemistry behind making cheese in this hands on activity.

Water is a precious natural resource. What happens if it gets polluted? Learn how water can be cleaned with this hands-on activity?

Learn about the chemical reaction that happens between acid rain and limestone.

Learn about acid-base reactions. Make you own pH indicator and test it with different solutions.
