Purpose The purpose of the homeostasis investigation project was to find our own way to test the presence of the process of homeostasis in our bodies.My group tested homeostasis through water levels in our body. We were to test how the water levels in our body changed due to a certain variable then to see how these levels returned to normal.
Abstract:For this lab, the first step that was done was to plan out the whole project. We came up with an idea that would test homeostasis by measuring water levels in our bodies. All three participants would run 800m and drink different amounts of water to see how their water content would fluctuate and then go back to normal. After this, the participants had to go to the track to test homeostasis. Then, we collected results and thought about what they meant and if we took the right data. In the end we had to go back and weigh ourselves a second time. After making revisions we made graphs and tables to express our data
introduction:Homeostasis is how the body maintains balance. Whether that be water content, body heat, energy, etc. Homeostasis uses different organs and hormones to regulate the body. When you exercise you use water to cool yourself. Our body has to regulate this water use so it doesn’t accidentally use all of it. Our kidneys, skin, gastrointestinal, and respiratory tract maintain our water balance by controlling the water concentration of our blood plasma. It also controls salt levels. The hormone anti-diuretic is what makes us thirsty and what makes us have to go to the bathroom. People actively sweat and pee to relieve ourselves of water and cool ourselves. To replenish this people rely on our kidneys and drinking water. While gaining and losing water, people gain and lose weight accordingly. Our hypothesis is the more water you drink, the less weight you’ll lose and if you drink less water, you’l lose more. Everyone will lose weight if they run. Our plan was to test how people’s water content would fluctuate and keep balance on and after a 800m run depending on how much water they drink.
Procedure and materials:
Procedure:
1. Go on a 400m track Have participant 2 drink 1000ml (2 bottles) of water
2. the other two participants drink nothing
3. Weigh all three participants and record their weights
4. All three participants run 400m (1 lap)
5. After the first lap, have participant #3 quickly drink 250ml (½ bottle) of water and weig hall three participants upon completion of the lap. Weigh participant #3 after they drink the water.
6. Have all three participants complete the second lap and then record all of their weights,again making sure participant #3 drinks 250ml (½ bottle) of water before weighing
7. Wait 10 minutes and weigh all three participants
Key term:
Speed-the rate at which someone or something is able to move or operate. This was shown in our lab on how fast we ran to see who would produce more sweat.
Weight- A unit of measure, ones mass. Shown by the starting weight and the finishing weight.
Scale- A weighing device that shows a measure of weight. This was used in our lab.
Velocity-the speed of something in a given direction. This was shown when the participants were running the track.
Homeostasis: The balance in the body that regulates bodily functions which range from body temperature to glucose levels.
Exhale: The process of breathing out.
Inhale: The process of breathing in.
Reflection:
There were a few skills that I got out of this project, one o them was learning how to make cheese and the whole process. Another one was what variable you can change to make any type of cheese.
Over the course of this project, there were several things that were done well, and somethings that could have been done better. In the former category, there are many things to be placed. My group had a couple peaks, one of them were my group worked very well together and what went poorly is time management. As a group, the fact that we had all worked together before meant that we more cohesive as a team. This lead to a better brainstorming process, resulting in more imaginative ways to achieve our goals. Also, this lead to more communication of ideas regarding individual working areas. This resulted in a higher quality end product.
The result of us working together also involved some issues. . One pitt was that was a distraction was by the friendly atmosphere, and resulted in a somewhat unproductive environment. The second pitt issue with this assignment was more administrative. The instructions, while intentioned to be brief, were the cause for much confusion in the class/group. It was unclear what the goal was of the project, and had to be clarified in greater detail.
Unable to get any pictures for this lab.
