Kinetics of the Acid Decomposition of Thiosulfate
9th - 12th
Several factors affect the rate of a chemical reaction including temperature, surface area, and concentration. Using an experimental approach, learners explore the effect concentration has on this rate while maintaining consistency with...
Energy—Gifted and Talented Chemistry
6th - 12th CCSS: Adaptable
What has more energy than a room full of pupils after a fire drill? This lesson plan! Explore the changes in energy during different chemical reactions, discover why some reactions feel cold and others feel hot, and tackle the concept of...
What Happens to Your Body When You Die?
4 mins 9th - Higher Ed CCSS: Adaptable
Your heart may not be pumping, but there are still many chemical reactions that continue in your body. An installment of a video series on chemical reactions describes the decomposition process of our bodies after death. It pays...
Turning Food Waste Into a Resource
5 mins 5th - 12th CCSS: Adaptable
One in every seven truckloads of perishable foods delivered to grocery stores gets thrown away. Is there anything that can be done with this waste? One solution is to recycle the old produce and turn it into fertilizer. The video, part...
Exothermic and Endothermic Reactions

The Area of All Polygons Through Composition and Decomposition
6th CCSS: Designed
To compose or decompose, that is the question. The fifth portion of a 22-part series presents area problems of polygons. Pupils determine how to compose or decompose the polygons into shapes whose area is easily calculated.
Solving Equations Using Balance Scale, Decomposition, and Graphing
7th - 9th
There's more than one way to solve an equation — three, actually. Scholars learn how to solve simple linear equations in one variable using three different methods, which include using balance scales, using decomposition (e.g., turning...
