I am looking for a classroom activity or project for grade 7 students. Students did one project creating models of flowers, plants, trees, and including the chemical equations and vocabulary as well. I'm looking for a better idea. Thanks.
I'm going to point you to my new favorite website WatchKnowLearn - Free Educational Videos for K-12 Students and ask you to search for photosynthesis & respiration to see what videos might meet your needs. All I ask is that you report back on any free videos you find useful. Inquiring minds want to know.
