Life Cycles and Survival in an Ecosystem

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.

Anchor Phenomenon: The pond is noisy with different animal sounds at night.

Driving Question: Why are the frogs so noisy and loud at the pond?

Engineering Design Challenge: 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.
