How did the gelatin in Cup 1 change? Did its ability to pass through the filter change?
Did the enzyme powder cause the change in Cup 1? What evidence do you have to support your answer?
What was the one difference between Cups 1 and 2? Was there a change to the gelatin in cup 2?
Which material from our lab was a metaphor for the bloodstream? In which cup did the gelatin’s nutrients reach the “bloodstream”?
Based on your experimental findings, why do you think it’s important for the food you eat to be digested?
How is food digested in the digestion system? What type of digestion did the model demonstrate?
What do you think would happen if you ate lots of food but couldn’t digest it? Would you still be hungry? Would you have lots of energy? Would you perform well in a sports competition? Explain!

1.I think that it made a hole in the paper stuff from the acid.
2. The stuff made part of the jello watery and it took the rest down.
3. The difference between cup 1 and cup 2 was that nothing happened to cup 2, but with cup 1 it made a hole and it got watery.
4. I think it took the nutrients out like our body does because it has enzymes.

5. It is important to digest food because if you don't it will just sit there and get hard and that might hurt you.

6. The experiment represented chemical digestion. I think it took the stuff it needed and left behind what it didn't need.

7. I don't think one could perform well in a sports game or competition if your food wasn't digested properly.

Which activities increased your heart rate the most?
Which activities increased your heart rate the least?
Was the order in which you ranked the activities accurate? (It's good to be wrong!) Explain.
What changes did you notice about your heart rate as you became more active?
Why do you think your heart rate changed when you were more active? What inference can you make? (Use pages 65–66 of your reference book to help you answer this question.)

1. The running activity made my heart pound because it was more exercise than sitting.

2. The sitting activity made my heart beat the least because I really wasn't doing anything.

3. I think It wasent because for some reason my heart beat more when I was standing than when I was walking.
4. I noticed that the more I moved the more my heart beat increased because I was exercising.
5. I think I changed because my heart was pumping blood realy fast so it pumped realy fast.

Building a Model Arm

How many bones did your model need? How many muscles did it need?
How were your pretend muscles similar and different to real muscles?
What would happen if the ligaments of the models were overstretched or torn? How would it affect the way the models could operate?
Explain what ligaments, tendons, and cartilage are.
What made this activity fun?
What made this activity challenging?

1. We needed 8 muscles for our elbow joint and 2 bones for the arm.

2. Our pretend muscles where similar to real muscles because they had all of the joints and but different because our model was made with different materials.

3. If the ligaments of the model where overstretched the arm wouldn't move. It would affect it because the bisepts would not bend the arms.

4. Cartilage prevents rubbing on the bones tendons hold the muscles together and the tendons make the bones move.

I5. It was fun because we had to figure out how to make everything work but it was still a fun challenge.

6. It was hard making things work.

Hyena was eating a sandwich,It was a grey day it was rainy and hyena was in his dark cave eating when he noticed something in the fog.It was a house! Hyena was so excited,but Miserable Hyena did not like getting wet.He crept out of his cave and a drop of water trickled down his nose,He quickly flicked it off he darted at the house but when he wasn't looking he fell into the river! Hyena began to climb out of the river and he thought i'm just going back home Its too wet and muddy.

Breathing Through Straws

What was the purpose of breathing through the straws?
While breathing through the wide straw, were some of the activities more difficult to do than others? If so, which ones?
How does your breathing change as you become more active? Why do these changes happen?
Why do you think that breathing through the wide straw caused the effects that you described?
Did breathing through the thin straw affect you differently than breathing through the wide straw? If so, explain why you think this occurred.
Why do you think you were asked to breathe through the thin straw for 20 seconds instead of 1 minute?
Why do you think you were not asked to walk or run while breathing through the thin straw?
How would your daily life be affected if you could only breathe in small amounts of air with each breath?

1. The propose was to feel what it feels like to have a problem with your lungs.
2. The sitting one was much easier than the running one.
3. As you become more active it becomes harder to breath and you are breathing harder.
4. I think breathing through the wide straw caused these effects because it was harder to breath in such a thin space.
5. The red straw made me feel sick when breathing and get a headache, as well as made me feel dizzy. It was a lot easier to breath with the wider straw.
6. Breathing through the thin straw for more than 2o seconds may cause you to faint.
7. If you run while breathing through the thin straw you could also faint and have shortness of breath.
8. It would effect me because I wouldn't be able to run and be active without feeling like I could breath deeply. This would cause me to be scared that I wouldn't be able to breath.
