Maine Learning Results

ME.A. Unifying Themes: Students apply the principles of systems, models, constancy and change, and scale in science and technology.
A.1. Systems: Students explain interactions between parts that make up whole man-made and natural things.
A.1.a. Give examples that show how individual parts of organisms, ecosystems, or man-made structures can influence one another.
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.2. Ecosystems: Students describe ways organisms depend upon, interact within, and change the living and non-living environment as well as ways the environment affects organisms.
E.2.c. Describe some of the ways in which organisms depend on one another, including animals carrying pollen and dispersing seeds.
E.2.d. Explain how the food of most animals can be traced back to plants and how animals use food for energy and repair.
E.2.e. Explain how organisms can affect the environment in different ways.
