Motion and Stability: Forces and Interactions
Investigate the resulting motion of objects when forces of different strengths and directions act upon them (e.g., object being pushed, object being pulled, two objects colliding).
Ecosystems: Interactions, Energy, and Dynamics
Distinguish between living and nonliving things and verify what living things need to survive (e.g., animals needing food, water, and air; plants needing nutrients, water, sunlight, and air).
Identify and plan possible solutions (e.g., reducing, reusing, recycling) to lessen the human impact on the local environment.
