What was the mission or aim of your project?
The aim of my individual project was to test which method of preserving seeds was the best because transporting seeds is much less expensive compared to growing plants on board we could also
Why was this your mission?
Planting the seeds was my mission because growing seeds on the ship would take up too much water and would be very costly but on the contrary freezing seeds to preserve them would lower the cost and would help us save drinkable water
What action/experiment did you take?
I experimented by freezing seeds to see if the growth would change, if they were shorter I failed but if anything else happened i succeeded and they not only grew and average amount they did better than expected
How did you use what you learned in grade 9 science in the design?
to freeze the seeds I need to have a knowledge of organic matter and living cells so that I don't ruin them

How does your project fit or connect with the other projects in the class? Are we living sustainably on your chosen planet.
mt project best fits with demitri because he was growing plants and I was reducing costs so that he could I was also keeping them alive
How successful was your action (its OK if it didn't go as planned)? Did you meet your goal?
It went as planned except for in the beginning when my group members betrayed me and made me change my plan entirely
What contributed to your groups success (or lack of success)?
miss q conveniently had plant heaters so they could grow without the sun
What would you do differently if you could?
I would change my idea and make crew living quarters and spaces inside the ship like storage and kitchens
What was the mission or aim of your project?
The aim of my experiment was to test if surrounding solar panels with mirrors would increase the voltage outputted from the solar panels.
Why was this your mission?
The reason why I wanted to test this was because the only practical source of energy in space is light from stars. There are no fossil fuels to burn in space, there is no water floating around in space, there is no wind in space, and if we tried bringing giant batteries or other energy storage devices we probably wouldn't make it through all 600 light years. Knowing this, it is best for us to find a renewable source of energy.
So, if we can extract as much energy and light from stars as possible we can make the trip faster and be able to recharge the ship's energy faster. And we know the only way to turn light into energy is using solar panels. But a lot of light is lost if it misses the solar panel, so what if we use mirrors to reflect that lost light into the solar panels to get more energy?
What action/experiment did you take?
To test my hypotheses of using mirrors to reflect light onto solar panels, I first needed to get myself a voltmeter in the form of a micro:bit. I found some code online that would allow the micro:bit to measure the voltage of the solar panel. Next I used some alligator clips and connected the solar panel to the micro:bit. Then I put a lamp pointed at the solar panel on a stand hovering over the solar panel that simulated nearby stars and suns in the universe. After that I got 4 square mirrors the same size as the solar panel and angled them towards the solar panel. Finally I turned on the light and measured the voltage without the mirrors, and then with the mirrors.
How did you use what you learned in grade 9 science in the design?
This experiment was all about electronics, so a lot of my learning from our electronics unit was used. I remembered that we used voltmeters in the unit, so I could use that as a device to measure the voltage from the solar panel. I knew that the positive end of the energy source (the solar panel) connected to the positive end of the micro:bit (Pin 0) and the negative end of the solar panel connected to the ground pin of the micro:bit. I also knew a little bit about coding and could code the micro:bit to measure voltage.

My experiment connects with the space suit section of the space camp project because charging anything at fast speeds will help with doing experiments in the spacesuit and allow us to be outside in our spacesuit for longer during the day because it doesn't take as long to charge up. We are living sustainably on Kepler-22b because solar energy is a renewable energy source and it is the best energy source on the planet because unless Kepler-22b's star disappears randomly, we have basically infinite energy from the star.
How successful was your action (its OK if it didn't go as planned)? Did you meet your goal?
Overall my experiment went as panned, although with some repercussions. In the beginning, the voltmeter I used before I had the micro:bit was a standard voltmeter with the red and black wires and a screen with the analog hand going left to right. This voltmeter had a wheel in the center of it which would change the multiplier of voltage measured on the voltmeter. For example the 10x option divided the voltage output by 10, but whatever reading you got you had to multiply by 10 to get the actual answer. So if the voltage went beyond the range of the voltmeter you would just increase the multiplier. But in my case that multiplier didn't work and all of my readings went past 1V so I had to find another way to measure the voltage of the solar panel which in this case was the micro: bit.
What contributed to your groups success (or lack of success)?
I was away for a lot of our space camp crunch weeks so I had very little time to get all of my data before the day of the science fair. But I was able to recoup quickly and get all of my data for my experiment in just 1 day which was very good since it was the last day to work on it.
What would you do differently if you could?
I probably would have used more solar panels and more mirrors to get more voltage out of the solar panels and see how much more the voltage would have changed without the mirrors and with the mirrors. Another thing I would change is the ambient light around me. In my classroom when I did my experiment the lights were off at the time so a lot of the ambient light was tooken away, but I would have preferred if I got rid of as much light as possible, basically doing this experiment in pitch blackness.
If you wanted to do this experiment yourself, I would recommend getting an actual multimeter or voltmeter to measure the voltage. You could also get more and/or bigger solar panels and/or bigger mirrors so you can get more accurate and more substantial results.
One way you can expand this project further is maybe testing if certian materials are more relfective than others. If my origional aim for this experiment was to get as much energy our from stars as possible, maybe you could go the extra mile and see if you can find things that can reflect more sunlight that just plain old decoration mirrors.
What was the mission or aim of your project?
The aim of my experiment was to test different materials strength to find which one would be best to build a spaceship out of.
Why was this your mission?
The reason i tested this is because if we don't choose the best material to build our spaceship out of we all die,there's asteroid fields, there's extreme cold and extreme heat and much more that could ruin our ship if we don't build it out of the best material.
What action/experiment did you take?
i experimented by dropping rocks of various sizes from various heights on to different materials

How successful was your action (its OK if it didn't go as planned)? Did you meet your goal?
my project went quite well
What contributed to your groups success (or lack of success)?
will being away made it difficult to coordinate
What would you do differently if you could?
i would test by freezing the material and then dropping then dropping the rocks to see how it handle in the cold vacuum of space
Will: What I learned from this experiment is how to better calculate the angle of reflection when light is hitting a mirror. In the first 2 weeks of the project, I was under the impression that the best angle would be 135 degrees, when in reality it was 117.5 degrees. I figured this out because when I was doing my testing for each of the angles (115, 125, 135, 145, 155) the voltage increased as the angle got closer to 115 degrees, so I thought something was wrong. I did some more research on this question and calculated that the optimal angle for the solar panel was at 117.5 degrees, so I learned how to better use the law of reflection. I also learned how to use a voltmeter properly. In the past I remember using them for testing how much energy was in batteries but that was it and I forgot how to use one after that, so now I can measure the voltage of anything. I also learned a bit of coding because I had to code my own voltmeter onto the micro:bit since the one the school was a bit broken. This was also the first science fair that I have every done so it was fun finally getting to have this experience of showing what you learned to everyone on a posterboard.
Sam: i learnt that plastic is awful for building a space ship but lego isn't
Connor: during this semester I learnt how to cultivate life and grow food I also learn't how to sustainably use the earth resources,I also learn't how to make meth, write a CER, what the scientific law was and how to calculate voltage, I learned how circuits work and how we can demonstrate proper lab safety not only for us but people around us I learn't that chemicals have different proporties, I also learn't how a periodic table works.
