Student Names: Mac & Ozzy
Ozzy and I’s experiment was to compare the gravity of Earth and Mars to understand the difference between the two planets. A simple difference in gravity can affect a human's health for many factors such as eyes, bones, muscles, and more. They can slowly deteriorate because they are no longer experiencing wear and tear therefore they are not trying to rebuild themselves stronger. The brain then realizes because they do not experience wear and tear there is no reason to continue to put energy and fuel into repairing them. So they stop and the muscle and bones begin to deteriorate and not strengthen until they are very weak. If we know how the gravity is on Mars and its difference from Earth we can potentially create an environment that is safe for the human body.
Through our research, we discovered that the ratio of Earth's gravity to Mars's gravity is 10:3 in centimeters. That is because Earth's gravity is 2.57 times faster than Mars. Meaning if we made the correct size parachutes and dropped them from the same distance Earth would hit the ground 2.57 times faster than Mars. We made the diameter of Earth's parachute 20.7cm in length and Mars's diameter 58cm in length. We dropped the parachutes from the top of floor 3’s staircase and they fell into the second-floor stairwell. We continued the trials five times so we would have the most correct results possible.
How Does Our Planet Connect to The Scientific Method?
Our project includes the scientific method because we follow the steps. Firstly, we observed videos on the difference between the two gravities and how to make parachutes. Secondly, we found our question. How long should the difference be between our Earth's parachutes falling and our Mars parachute falling? Thirdly, we wrote out a hypothesis based on the ratio that earth had a 2.57 times faster/stronger gravity than Mars. Fourthly we made a plan on how to make a parachute, then how we were to time and drop them and in what order. Fifthly, we dropped both parachutes in the same distance stairwell so that we had the most persistent results possible. Sixthly we calculated if the drops times added up to our expected times with only .3 second room of flaw. For imperfect dropping because we could not control if it landed in one higher step or not. Lastly, we wrote a conclusion on how we got the result we did. We also had the independent variable of the length of the diameter of our parachutes. The dependent variables of how Earth's gravity is 2.57 times faster/ stronger than Mars and the distance we dropped our parachutes from.
How Does Our experiment Connect to Space?
Our experiment connects to space because we calculated the gravity of Mars which is in space and the gravity on earth and compared the two. We were trying to understand what circumstances we would be living in if we lived on Mars. How living in space on the different planet of mars would be different/how different than living on our world Earth.
How Does Our Experiment Connect to Biology/Ecosystems:
When we understand the gravity of Mars we can start brainstorming ideas on how we are going to live and thrive there. For example how the house can be made to allow humans to stay healthy and on top of the food chain. Also barns and space for livestock. Years from now the possibility of livestock being on Mars with us is possible. If we want them to continue reproducing and thriving we need to allow them to have a proper environment for their needs to grow and continue their chain in biodiversity. We also need to have clean water for animals, plants, and humans so our experiment connects to the water filtration system with their clean water ideas. We also need to understand Martian soil to plant produce and hopefully medicines so we are connected to the water filtration system as well because of their knowledge of the Martian soil after working with it.
Our experiment does connect with other classmates' experiments because of many reasons. Firstly, we need to hydrate and cleanse ourselves and our parachutes with clean water therefore need a water filtration system. Secondly, we need food to sustain ourselves so we can use the parachutes so we are connected to the food group. Thirdly, we need the energy to get to parachutes to space so the electricity in the space group is connected to our group. Lastly, we need many things to stay alive so that is why all the groups are connected to use.
Our group was successful because we had a 0.3-second error falt. That means that it is probably to do with slightly delayed timings or landing a step ahead of each other. Our hypothesis was correct and we completed the experiment the way we needed to show the ratio of Earth's to Mar's gravity is 2.57 seconds faster.
Our ability of has lots of time helped us focus on everything we had to do. We made a checklist and quickly checked things off making sure our experiment worked throughout. We also were very determined because our first Earth parachute which took a whole class to make came out to be the diameter was short meaning we had to remake it. That was our biggest challenge but we overcame it and made a new one.
If I could do something differently it would be to also build a model of how gravity affects the human body not just knowing about it/writing about it and the gravity parachutes project.
Pitch the next phase of your project.
Next, we could build a project showing how long the bones and muscles take to deteriorate. We could also show how and what could keep them to continue strengthening themselves so when the astronauts came back they would have their usual mobility.
Inspire a future group of students to pick up where you left off.
Another group of students could create the same experiment but compare different planets that could one day potentially hold human life. For example Venus or maybe try mercury. They can understand how strong the gravity is and if it is livable.
Why is this an important cause? Why should they continue with it?
This is important because one day the world will be not enough to sustain human life because of problems like pollution, overpopulation, war, power, and overall further learning. It is connected to gravity because we need to understand gravity on a specific planet in order to know how we will live and in what shelter to protect us from the gravitational force.
Where would you like to see it go next.
I would like to see our parachutes be larger, made of better quality, and dropped from a higher distance like a roof. Because then we can visualize what it will look like connected to a real person and how much bigger it would need to be in order to hold a person. It will then be a more realistic version of what we are trying to achieve.
Each member of the group should reflect on what they learned. You may have learned some neat stuff about science, but you also learned some other great skills like time management, goal setting, collaboration, and problem-solving.
Mac- During this part of the course, I have learned lots of new skills. Firstly, I have learned that when there are any deadlines you need to make sure you are using all your class time as efficiently as possible in order to succeed the most. Secondly, I learned to communicate with my group members. With some of my group members, I was consistently talking and sharing ideas and was getting thoughts back as well. With others, however, we failed to communicate and were sorry later. Because of that we now have learned something valuable for the future, COMMUNICATE with your peers. Lastly, I learned that planning out your time is key. Ozzy and I consistently checked off are list making sure we got our whole experiment done as well as possible. In conclusion, I have learned lots of cool science about gravity, mars, earth, and overall human health. I am now much stronger in calculations, ratios, and scientific notations. As well as the scientific method with the trial and error process. I had a lot of fun working hard with my team and now understand much more about how gravity affects health in science.
