In class we got to do an experiment for our respiratory system paper. We tried to breath through different sized straws while doing various activities. Then we had to answer some questions about the experiment.

Question #1: Were some of the activities more difficult to do while breathing through the wide straw than others?
Answer: Doing the jumping jacks and breathing through the wide straw was harder than sitting down or walking. I needed more oxygen so I had to breathe faster.

Question #2: Why do you think that breathing through the wide straw caused the effects the you described?
Answer: I think it was because the wide straw had a bigger diameter and more air could travel through it. Even when I was more active I could still get enough oxygen in.

Question #3: Did breathing through the thin straw affect you differently than breathing through the wide straw?
Answer: It was harder to breathe through the thin straw because it had a smaller diameter. I had to take big breaths to get a small amount of air.

Question #4: How does your breathing change as you become more active? Why do these changes happen?
Answer: My breathing became faster as I moved more because as I moved  my body needed more oxygen intake. At first I was restig and didn't need a lotof oxygen but soon I needed more becay

 

In class we do this thing called passion time. In passion time you're allowed to read or research things that you're passionate about. I like to read for passion time because in each book there is a new plot. Right now I am reading a book called The Floating Island. It is a great book.

    There are many different causes of the Revolutionary War.
For example, when the colonists retaliated to the Tea Act by throwing the tea away into the harbor the British passed more laws called the Intolerable Acts. But, when the British passed the Townshend Acts the colonists decided to boycott British goods. Also, when the British passed the Quartering Act which forced the colonists to house soldiers the colonists taunted the soldiers and the effect of the taunting resulted in the Boston Massacre.
    I think we are learning about the causes of the Revolutionary War because if we learn about the Revolutionary War but don't know what caused it we might get confused of why it even happened.
(P.S. For some reason creately didn't put all the words in the Causes of the Revolutionary War above. Boston Massacre, Townshend Acts, the Quartering Act, the Tea Act, the Stamp Act, the Currency Act, the Quebec Act)
    

    This graph show the average amount of times my heart pumps in a minute during different activities. When I was running in circles my heart pumped the fastest because I was moving around. When I was completely still my heart rate was low because I didn't require as much blood to be pumped around my body. I think I ranked the activities accurate because I put lower heart beating activities first. As I became more active my heart rate increased because I needed more blood to my body. At first it was low because I wasn't moving much but gradually it became higher.
My heart rate changed because as I became more active and more blood was required to deliver oxygen to my muscles to keep them going.
