Cut the area into two. Pupils see how to use algebraic expressions to find the area of a composite figure. The video breaks the figure into two rectangles and finds the missing lengths to find the area. After multiplying the dimensions,...

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...

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...

Humans have both positive and negative impacts on biodiversity. A video lesson highlights important human impacts on biodiversity through examples and diagrams. The narrator provides insight to the progression of the topic from...

Break down a great lesson on decomposition reaction with an informative video. Fourth in a 35-part series, the resource builds from the previous lesson explaining the role of a catalyst. The detailed video explains the experimental...

What do decomposers and a compost have in common? Decomposers help a compost break down, or decompose, things that can biodegrade and become similar matter. Watch a video that explores the science of composts.

Burial practices are the focus of a short video that not only investigate how and why bodies decompose, but also looks at some modern approaches to the treatment of bodies and burials.

Hear how carbon functions on our earth and the purpose it serves. The carbon cycle is illustrated with narration for your junior high or high school biologists. Global temperature increase is also included, though the clip cuts off...
