Life Science is the study of life on earth. In middle grades, it is an introductory biology class. The following is a breakdown of many of the topics studied in life science and a video link for each topic. I create a daily animated science video. Each video is three to four minutes long and is geared towards middle grades and introductory high school classes.

Organisms that live in each biome have adapted to the amount of rainfall and climate.
