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. I can feel when my eyes dilate because when i am in the light I squint my eyes and when I am in the darkness they start to open up more. 

2. You do not have any control over when your eyes dilate because when you are in the dark they get bigger but when you are in the light they get smaller.

3. We call this sensory nerves, and motor nerves. 

4. Our pupils get smaller when we are in the light because our eyes are so sencitive to such bright light but when we are in the dark they close up because it does not hurt them. 

5. This reflex protects our eyes because if we were staring at the sun all day then we would be blind. 

1. Catching the ruler with my eyes closed was harder then catching it with my eyes open because I could not see it an I didn't know that it was in the air and I didn't know when I should grab it. 

2. I could use the sense of smell for catching the ruler because I could feel the air/ wind so I know when to catch it. 

3. I think that I could catch the ruler by sense of taste  
if someone dropped something really sour or really sweet onto my tongue.
4. I think that my brain and my nerves  in my fingers really helped me because if I didn't have nerves.  then the ruler would just slide through my hands. My brain also helped me a lot because without my brain then I would not know when I should tighten my hands to be able to catch it.  

5.  My body responded to the paper hitting the clear paper by flinching because since I can see through the paper it made me feel like the paper was going to break the clear paper and hurt my eyes. 

6. This reflex would have protected my eyes if the transparency was not there because the paper ball might have cut my eye or it could have poked it and both of those reasons would probably hurt really bad.   

7. I do think that the nervous system responded to both blinking and catching the ruler in the same way because when we getting paper thrown at us we some of us flinched so that made us be like who I did not see that coming and for the catching the ruler was much harder then I thought that it was going to be.

 1. Yes it was difficult because my hand was getting really tired and I wanted to change my position with my hand but I couldn't

2. Before I was like this is going to be really easy and I wasn't scared at all. During it I was moaning a I was like this is a lot harder than I thought it was going to be.

3. On my data table it shows it decreases a little bit then towards the middle it's pretty straight.

4. The pattern told me that I did pretty good because My graph is not zig zag it's a straight line.

5. I think that my results are reliable because I could tell that I was counting right and it wasn't like two much where you could tell that I was counting wrong but I accidentally started late a few times and Mr. Solarz rubbed my hands so it felt a little better not to sore.


6. I think that my hand strength changed because I was pinching as fast as i could for 30 seconds straight for 10 times so it got tired over time. The first time i did it was really easy but the last time i did it was really hard because I had already done it for 9 times before that.

7. I think that they got the oxygen and nutrients they needed by taking a rest and shaking my hand off because then it would be relaxing and when Mr. Solarz rubbed my hand it really helped.


8. I think I could of asked Mr. Solarz to do the rubbing hand thing more often because it felt better after he did it to me. After he did it to me I think I got more pinches on the clothes pin.


9. You should take a few seconds to relax your hand and rub it a little bit so it doesn't throb to much if it really hurts.
