Reflection Questions | Answers |
| 1. When the paper ball was thrown at the transparent sheet of paper, I blinked and sort of flinched and leaned back. When my partner, Tyler got hit with the paper ball blinked and squinted really hard. However, Andrew just blinked. I think Andrew had the least amount of reaction. 2. The reflex would have made you blinked to protect something going in your eye. Also I described that I flinched and leaned back and this will help without the transparency because it will help you doge or not get hit as hard with the paper ball. |

Reflection Questions
| Answers1. Yes. Hearing was more harder than sense and touch. I think this because we both chose poor phrases or noises that lasted a while. I said "Lebron James" and Alex did some sort of cat screeching voice. These lasted a little longer than other things people would say and it distracted our reaction to catching the ruler. 2. We could smell our snacks and right away when the person who would catch the ruler would smell the snack and the other person would drop the ruler. I think this would be more difficult but it would work. 3. You could do something similar to the sense. You could eat the snack instead of smelling it. 4. When your partner was touching you, blinking at you, or yelling a weird voice indicating that he is going to drop the ruler, your eyes, skin, or ears send a message to the brain saying that Alex is going to drop the ruler. |
Conclusion to Human Body Lesson 14
1. Do you think the nervous system responded to catching the ruler and blinking in the same way? Why or why not? Were the senses used in both? Were muscles used in both? Did you have to think about both actions? | 1. Yes. I think this because we both used our sense of sight to see the paper ball flying at us and when we were trying to catch the ruler. Muscles were also used in both because your muscle helped you hold on to the ruler and your muscles also helped you with blinking your eyes. No. I didn't because when you had a paper ball flying at you you wouldn't just think about blinking, it is an instant reflex to blink to protect your eyes. It's the same way with the ruler when your partner made you use one of the senses to catch the ruler, the very second he touched you, blinked, or made a weird voice, that is an instant reflex to realize that he is dropping the ruler. |

Reflection Questions Then answer these questions as well: 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? | Answerse1. Yes I can. When the lights went out, after a while I felt my eyes get strained. Your pupils get bigger to see in the dark and having big pupils means that it is harder to see. Seeing in the dark puts twice as much strain on your eyes than seeing in normal light. 2. No. Only if you count when you turn off the lights and on to change how big and small your pupil is. 3. It is called an involuntary or automatic action. 4. Our pupils get bigger in the dark because it is harder to see in the dark. Pupils help you see and they need to expand to see better. Our pupils get smaller in the light because they don't want your eyes to get strained. You are pretty much expanding your pupils for no apparent reason and even after a while in the dark, my eyes got strained so I can't imagine having big pupils in the light. I take that back when I go to the eye doctor, They expand my pupils to look into my eyes and it usually lasts a while. When I walk outside I can literally see nothing and I scream, " MOM I NEED SUNGLASSES! " because you are trying to over see when you have light and you can't see and you are sensitive to the light like a vampire. 5. This reflex protects your eyes because your pupils get bigger when you're in the dark and is helps you see your surroundings in the dark. Your pupils get smaller when your outside on a sunny day to protect you from the sun blinding you. |
