Life Science The structure, characteristics, basic needs and diversity of living organisms. 2

Life Science Life science is the study of the structure, characteristics, basic needs and diversity of living organisms. Key components include: Matter, energy and organization in living systems Diversity and biological evolution Reproduction and heredity 3

Life Science K-2 Level Investigations Matter, Energy and Organization in Living Systems 1. Investigate the basic needs of humans and other organisms. –Humans Food, Clothing (protection), Shelter –Animals Food, Shelter Animals develop their own protection –Plants Correct climate, temperature, rainfall 4

Life Science K-2 Level Investigations Matter, Energy and Organization in Living Systems 2. Compare and contrast essential characteristics that distinguish living things from nonliving things. 5
