# Unit Review: Key Concepts
  • Muscles pull on bones to create movement.
  • Eyes are sensory organs that receive information about the world.
  • Light enters the eye, which provides information about surroundings.
  • The pupil gets larger to let more light in when it is dark.
  • The brain receives information from the senses, processes the information, and controls the muscles to enable movement.

# Unit Review: Owl System Model

If you haven’t completed your final Owl System Model worksheet, now is the time to do so. We’ll review how the owl senses and responds to its environment in the next few slides.

Step 5: The owl’s muscles receive the signal and pull on the bones, creating movement. The wings flap and the claws contract.

In today’s activity, you will use your owl system model to help you explain how another animal or plant senses information, processes it, and responds to its environment.

We’ll walk you through it, step by step.
