The dark opening in the center of the eye.
What does nocturnal mean?
You are mostly active at night.
Why do we get better at experiments like dropping the ruler the more we do them?
Our brains are learning what to and we get better at knowing what is coming! (it is called neuroplasticity)
Stimulus: You see a friend fall
Tell me the process that happens with nerves, your brain, and your muscles.
The eyes see the fall and send a message to the brain, the brain decides what to do, and sends a message through your nerves to your feet or hands to go and help them.
Why are bones important?
They are what keep us structured, we need the the hardness of our bones because they give our bodies shape.
What is the iris?

What are nerves?
Parts of the body that carry signals from one part of the body to another part.
Stimulus: Touch something pokey
Tell me the process that happens with nerves, your brain, and your muscles.
The hands feel something and send a message to the brain, the brain decides what to do, and sends a message through your nerves to your hands to stop touching the thing.
What are tendons?
The part of the body that attaches muscle to bone.
Why do some people have blurry vision?

Why can nocturnal animals see so well in the dark?
They have a reflective layer on the back of their eye that brightens the surroundings and their pupils can get really big that lets in as much light as possible.
What are sensory nerves?
The parts of the body that carry signals from the senses to the brain. (Eyes, ears, nose, mouth, and skin)
Stimulus: You eat something sweet.

Why do our pupils change depending on how bright or dark it is.
They need to let in more light, so they get bigger when it is a darker place.
What are the motor nerves?
The parts of the body that carry signals from the brain to muscles.
Stimulus: You hear someone call for help.
Tell me the process that happens with nerves, your brain, and your muscles. Be specific with what nerves are working when.
Your ears hear someone and send a message to the brain with your sensory nerves, the brain decides what to do, and sends a message through your motor nerves to your feet to go and help them.
It showed us how the joints move when the tendons gets pulled on by muscles. How we move!
What does the retina do?
It senses light and sends messages to the brain.
Why are some people fully blind?
They do not have a cornea lens.
What is the nervous system in your body?
The brain and all the nerves in the body.
Stimulus: You smell something baking in the oven.
Tell me the process that happens with nerves, your brain, and your muscles. Be specific with what nerves are working when.
The nose smells something yummy and send a message to the brain with your sensory nerves, the brain decides what to do, and sends a message through your motor nerves to your feet or hands to go and walk and open the oven to see what it is.
