Enzymes in Action: An Inquiry Approach to the Effects of Enzymes

Putting glow sticks in the freezer makes them last longer, but why is that? Lesson focuses on how temperature impacts the rate of a chemical reaction. It begins with a teacher demonstration, then scholars design their own experiments...

Start this series of lessons with a bang! Five exothermic reactions are outlined in this resource, including a demonstration that produces both light and sound. In the lab, chemistry apprentices record temperature changes, make hand...

Biochemists experiment with the oxothermic decomposition of hydrogen dioxide by adding manganese dioxide. They observe how pepsin enhances the action of acid on the digestion of egg white proteins. They use yeast to make bread rise. All...

When a candle burns down, what happens to the mass that appears to be shrinking? Lesson begins with a demonstration of the chemical reaction of a candle burning. Then scholars use atom models to observe conservation of mass concretely. 

Some chemical reactions produce heat, but what is really going on? Lesson focuses on the concept of energy changes, both exothermic and endothermic. Scholars perform multiple experiments, hands-on activities, and view videos of the...

Teach the basics of writing chemical equations with a video introduction. The video lesson discusses the components of the chemical reaction and how chemical equations represent each. The discussion includes mention of catalysts and...

Students are introduced to the process of balancing chemical equations. First, students see that a chemical equation describes the chemical reaction that takes place when two elements are combined together. In the world of chemistry,...

This site provides an overview of the role of energy in chemical reactions.

Chemical reactions are constantly happening in your body - even at this very moment. But what catalyzes these important reactions? Vance Kite explains how enzymes assist the process, while providing a light-hearted way to remember how...

Review key terms after your lecture about chemical reactions with this crossword puzzle. Eleven questions prompt students to refer to their textbooks, lecture notes, and prior knowledge. This assignment would be a good homework...
