Take it or leaf it, the video teaches the structure of leaves. It includes a discussion of stomata and the importance of transpiration. It also explains the role of chloroplasts.

Why do leaves change color in the fall? The video explains the relationship between chlorophyll and light, connects the concepts of light to photosynthesis, relates the visible color spectrum to electromagnetic radiation. 

Trees' leaves change all year round. The cycle is continuous from green to red to orange to brown until dead. Watch a video that explains this cycle and the science behind a tree's need to shed its leaves.

Discuss what nutrients plants require and where they get them from. An informative video explains the dermal, vascular, and ground tissue in both monocot and dicot roots, as well as stems and leaves. 

How do plants get the nutrients they need? This is the focus of a video that discusses how plants use photosynthesis to survive, with or without dirt.

Here is a cute presentation for middle schoolers on the photosynthesis process. Each required product is named and then the process is viewed in a cartoon cross-section of the leaf. Embed this little video into your own PowerPoint or...
