ME.A. Unifying Themes: Students apply the principles of systems, models, constancy and change, and scale in science and technology.
A.1. Systems: Students recognize that parts work together, and make up whole man-made and natural objects.
A.1.a. Explain that most man-made and natural objects are made of parts.
ME.E. The Living Environment: Students understand that cells are the basic unit of life, that all life as we know it has evolved through genetic transfer and natural selection to create a great diversity of organisms, and that these organisms create interdependent webs through which matter and energy flow. Students understand similarities and differences between humans and other organisms and the interconnections of these interdependent webs.
E.1. Biodiversity: Students describe similarities and differences in the observable behaviors, features, and needs of plants and animals.
E.1.a. Describe similarities and differences in the way plants and animals look and the things that they do.
E.1.b. Describe some features of plants and animals that help them live in different environments.
E.2. Ecosystems: Students understand how plants and animals depend on each other and the environment in which they live.
E.2.a. Explain that animals use plants and other animals for food, shelter, and nesting.
E.3. Cells: Students describe parts and wholes of living things, their basic needs, and the structures and processes that help them stay alive.
E.3.a. List living things and their parts.
E.3.c. List the basic things that most organisms need to survive.
E.3.d. Identify structures that help organisms do things to stay alive.
