Which Joints Are Most Important?

12/10/2013

Which joint did you choose as our most important joint?

I chose the jaw as the most important joint.

Why did you choose that joint?

I chose the jaw because you need it to chew and swallow. Food is an important part of life, and you can't get it into your body many other ways.

What things would be difficult to do without that joint?

Eating and talking.

What movement can be done without the use of joints? (Example: blinking your eyes)

Well, blinking your eyes, but also humming, and crossing your eyes.

Signs of Exertion

Observation:

My heart rate went up.
We were panting.
My feet were burning.
My face was red.
I was exhausted.

Explanation:

It is pumping blood faster to the parts of our body that needed it.
Respiratory system was struggling to get air to our bodies.
Our muscles were tired.
Blood got transported to our faces really fast.
Our bodies were working too hard.

Questions:

What three basic things do our bodies need in order to survive?

We need food, water, and energy to survive.

If we exert ourselves, what are three (or more) signs that our bodies are in distress? Explain why our body does that (research it if you need to).

Heart rate went up: It is pumping blood faster to the parts of our body that needed it.
Panting: Respiratory system was struggling to get air to our bodies.
Feet Burning: Our muscles were tired.
Red Face: Blood got transported to our faces really fast.
Exhaustion: Our bodies were working too hard.

What can we do to make these signs go away?

We can rest our bodies.

How Might Humans and Aliens be Different?

Humans

Human Adaptations:

Our gravity allows us to stand on two legs.
We have one ear on the left side of our head, and one on the right to hear all around.
Our eyes work better in the daytime than in the night.
We can use our arms and/or legs to help us stand and support our weight.
Our brain allows us to do complex things that other living things cannot, such as doing worksheets and using computers.

Aliens

A description of my alien's planet.

Alien Adaptations:

The alien needs the slime blob to stick on the slimy surface in the low gravity and also to collect algae and lichen inside the slime and give it to the alien.

The alien needs this skirt-type thing because it provides an area of skin where sun and light can enter for photosynthesis.

The alien needs these eyes for the same reason as the skirt thing, and also to see where its prey is.

Do we have cells similar to the aliens you created? How or why not?

We have some similar cells in our bodies (cells that make up eyes) as well as some different cells (slime blob).

Humans (and probably aliens) have cells that have special functions. What are some of these cells and what organs and systems are they a part of? Give at least three examples and be specific. (Example: Osteoclasts are cells that make up spongy bone inside of many of our bones. This is part of the skeletal system.)

    1. What was the hardest part of this activity?

    Well, I think it was either putting the organs in places that made sense to both of us, with the right sizes and             shapes or watching kids go to recess right in front of us.

    2. What organs do you think you got in the right places?

    I think that, really, we only got, like, 5 right. Those were the brain, eyes, lungs, heart, and skin.

    3. What organs do you think you got wrong?
    As I said, I think we only got, like, 5 right. The ones we got wrong were the ones not mentioned above
    (see above).

Hi! My name is Zeynep Kocak. I am a geologist from Turkey. It is important to have this job on Mars because there are lots of new specimens, and someone has to know how to study them. I am excited about this because I have not studied Mars before, and it will be a new and challenging experience.
