1. Can you feel it when your pupils dilate?
2. Do you have any control over your pupils when they dilate?
3. What do we call this when a reflex happens without our control?
4. Why do our pupils get bigger in the dark and smaller in the light?
5. How does this reflex protect our eyes?

1.You can sort of feel it because when the paper ball is thrown you kid of flinch and you can feel your self flinch.

2. No you don't because we either fight or flee and one of your reflexes is flinching which goes with fleeing. We don't have control over them every one is born with these instincts fight or flee.

3. We call it instincts.

4. They do that because you have enough light to see so and it does not need too much light so the make the hole in our eye smaller so not that much light can get in.

5. Lets say some one has something in there hand and they throw it at you and it is going for your eye and you close your eyes because of your reflexes so the thing does not hit your eye and it protects you from a harmful injury.

1. My partner was watching when the ruler dropped she pinched. When she pinched she caught the ruler.

2. My partner said 3 2 1 and then she dropped the ruler and it actually worked out good i got a 3 on that one.

3. We just kicked our partners chair when we would drop the ruler. It worked out good I got 3 in the sense of touch.

4. Yes it was it was harder to see when you drop the ruler. You can't know when exactly the ruler is going to drop. The others you knew exactly when the ruler was going to drop

5. I think you can put something that smell is really strong and and put is by the end of the ruler and when you think the smell is really strong you pinch.

6. You can put some food at the start of the ruler and once you taste the food on the ruler you can pinch the ruler.

7.  At first your eyes see the ruler being dropped and the they send a message to the brain the brain made a decision to grab the ruler. Your brain send a message to your hand muscles and tole them to pull. Then your muscles moved to grab the ruler.
