100 word challenge. Aliens, Light and Jack

2/20/2014

A dark night, me and Jack were walking in this haunted house trail. It was hard to see, we were getting blinded by a crazy light. Somewhere on top of this hill was this yellow house. That is where the light was shining. It was beat down. It had moss on the roof and the door and windows where bricked in. We were walking to it, when we saw a neon figure. It rushed to the light. We chased after him, that light that we thought wasn't shining at the house it was a thing not light it was a Alien.

Was it more difficult to catch the ruler using one of the senses as compared to the other? Explain.
How could you use only the sense of smell to catch the ruler?
How could you use only the sense of taste to catch the ruler?
Explain how your senses, nerves, brain, and muscles in your fingers helped you to catch the ruler for one of the senses explored. Use pages 17-23 of your student reference book to help you.
How did your body respond when the ball of paper was thrown at you?
How would this reflex protect your eyes if the transparency had not been there?
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?

Yes. I thought that my senses work better with sound. That was my best one.
You could used the sense of smell to trigger the pinch by the smell of a mint and when they smell the minty smell they then will try to catch the ruler.
For catching the ruler from just the sense of taste you could have the person stick out their tongue and when you place a mint on their tongue. When they taste the mint they can try to catch the ruler.
First the nerves or senses notice that the ruler is coming by the thing you decided would be the trigger. Once the trigger happened it would signal a message to the brain which will send a message to the muscles in your finger to pinch and try to catch the ruler.
I flinch and shut my eyes because my brain thought the ball was coming.
It would protect my eyes from getting a cut because my eyes where closed and they were moved out of the way from the flinch.
No because one of the reflex is to protect you the other one is more of you knowing when blank is going to happen you need to blank.

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?

No. Because it is a reflex that you don't know happens.
No. Because it is a involuntary reflex just like involuntary muscles.
A involuntary reflex it means you don't notice it happening and it go's on by your mind not by you.
So that they can let the right amount of light in your eyes.
If you didn't have this reflex your eyes could burn out.

How many heart beats did you think you would have in one year before extrapolating? Were you close or far off?
Explain what "extrapolating" means to younger children.
What are some other things you can extrapolate? Give some examples.

Reflection Answers:

1. I think I will get 65,000,000 beats in a year. I think I was pretty close because my number was really big.

2. Extrapolating means to keep multiplying it over and over.
3. You can extrapolate a recipe. Like if you need 1/4 cup of sugar for 4 people but you have 20 people.
