NEW! Life Cycles and Survival in an Ecosystem
3LNG - 3rd Grade - Life Science (NGSS)
Students continue to explore the balance in an ecosystem and the dependency of organisms within the system. They develop models of the life cycles of a variety of organisms. Students determine how some organisms survive well where others do not. They compare data from fossils to modern organisms.
Design and construct a model to demonstrate how problems in populations occur when the environment changes. Determine the merit of a possible solution to the problem.
