Model of a Lung

Aim: I want to create a model of a lung

Equipment: Plastic cup, straw, balloon, an elastic band or hair tie. This is all the list need to make a model of a lung.

Method:
1.)make a hole at the cup's bottom
2.)Put the balloon on the 2 straw
3.) Then put it inside the cup and out the sprout of the cup
4.) Take another balloon and cut the top of it off
5.) Then put this balloon on the bottom of the cup so that it covers the opening.
6.) Apply elastic band or something that will keep the air from going inside through the cup (to me I would recommend you to use hot glue )
7.)To work the model, pull the bottom balloon. You can see the lungs grow bigger, this is how your lungs work.

Discussion:
What are the Lungs?
is a pair of organs situated within the ribcage. The ribcage protect your lungs and your heart, your ribs also move when you breathe in and out. The left lung is smaller than the right lung because it has to make a room for your heart. Below your lungs are the diaphragm, the diaphragm is a muscle that works with your lungs to breathe in and out.

What do lungs do?
Air wooshes to your nose and mouth through your trachea and divides into left and a right tube called bronchi which connect to the lungs. Within the lungs, the bronchi branch into smaller bronchi and even smaller tubes called bronchioles which are as thin as a strand of hair, end in tiny air sacs called alveoli. The air you breathe in fills these sacks, causing the lungs to inflate, at this point the capillaries are packed with carbon dioxide, and air sacks are full of oxygen. In the process called diffusion, each gas wants to move a place where there's a lower of their kind so the oxygen crosses over the capillaries the hemoglobin grabs it up while carbon dioxide is unloaded into the lungs, hemoglobin is a protein inside the red blood cells that carries oxygen to cells and carbon dioxide. Then the oxygen is transported throughout the body and then we exhaled the carbon dioxide causing our diaphragm to relax and the volume of the lungs gets smaller.

The process of diffusion
the molecules of each gas want to move to a place where there's a lower
of their kind. So oxygen cross over to the capillaries, the hemoglobin grab
it's up while the carbon dioxide is unloaded into the lungs. The oxygen-rich to the hemoglobin
is then transported throughout the body via the bloodstream and then we exhale the carbon dioxide.



Fun facts about Lungs
1.) Lungs can float on the water
2.) Lungs aren't the same size

3.) Lungs and tennis court can be the same size
4.) An average person can breathe in 11,000 litres of air a day
5.) Without mucus, your lungs will dry up


Evaluation:
This is my complete Lung model, I am proud of what I did, but next time I'm gonna use strong equipment that can support my model. I should've used hot glue for the straw because the straw wouldn't let in the right position. If you were to create my model I would recommend you to use a plastic bottle because it's much stronger than the plastic cup, use a hot glue gun instead of a rubber band or hair tie and I would recommend fixing the mistakes I made. I enjoyed making this model and it only takes 20-30 minutes to finish. If I want to learn more about the Lungs, I want to extract from the Pig and investigate it.

What am I learning?
I learned how to make a model of a Lung and how does lung work
I am wondering?
I'm wondering if you can drown inside and out.

English Essay

A character who changed in the Zootopia is Nick when he meets Judy in the Zootopia. Nick changed from bad to good because when chief Bogo ask Judy for a badge Nick stands up for Judy because Judy saves his life.

Nick began as a Junior Ranger scout even he was the only predator in the troop but he got bullied by his troops. This is because when Nick promised to be brave, Loyal, helpful, and trustworthy to his troops. Nick told Judy that he learned two things that day that he was never gonna let everyone see that they got to him and if the world's only gonna see a fox and shifty and untrustworthy. Judy said " Nick, you are so much more than that", this helps the audience to realize when someone is having a hard time, there's one friend that can help you solve your life problem.

In the middle of the film where Judy was answering questions to the reporters and Nick is being irrational after Judy's speech. This is because Judy said to the reporters that predators may go back to their savage ways. We can see that Nick is upset and confused, she asked Judy if she's afraid of him or does she thinks he might go nuts. I think, in this scene, we know that Judy has a right to be protective but we also have to think before we speak to others so that they can understand.

At the end of the film, Judy and Nick solve the case and Nick became a part of ZPD. This is because of not giving up and how we should understand each other. Judy made a speech said, " real life is messy, we all make mistakes, and the more we understand one another, the more exceptional into us will be".  I think the director wanted us to understand that we should not give up our hopes and we should try to make our world a better place.

Nick was different at first but he changed when she meets Judy. They help each other to reach their goal and solves their problems. I think the creators made this movie that everyone is represented as both predators and preys that shows not everyone is what you think what they are.
