Passion Project on Exoplanets Day #1

In school everyone had the choice of doing a passion project. This is like a mini capstone. At first I didn’t know what to do so I thought I wasn’t going to do the passion project but then I decided to do it on Exoplanets because I’m interested into space. Exoplanets are planets outside of our solar system that orbit a star. Today for my research I focused on how do you discover Exoplanets? I surfed the web until I found a reliable resource to use. I understood the concept of Radial velocity easily but what confused me was Micro lensing. It was confusing because the word ‘light’ appeared so many times and I couldn’t picture it in my head until I read it many times, then I finally understood how it worked.

Science, making water filters

This unit in science we have been working on water filters. Throughout February we were working on designs and materials for water filters. We were also talking about rivers and water sources that are polluted in different ways, we also talked about how important clean water is for humans. For this science unit we also read a book called Saving Salila’s Turtle in our science groups. Saving Salila’s Turtle is a book where a girl named Salila who tries to save a turtle in the polluted Ganges river, later in the book she designs a filter to make the water clean for the turtle’s water tank.

Finally today we made our first water filter designed by ourselves. Our first design of a water filter had materials that consisted of two screens, sand and gravel, and a wipe. Our group wanted to use screens because they would get out all the big particles, we wanted sand and gravel because before we tested it out and it cleaned out the polluted water very well and we wanted the wipe because it’s holes are not visible to the naked eye, only the water could get through. We got scored on each of the final products. We got scored two to three for this design, its color looked the same as the graded example three, but it had no particles at all. Our first water filter design did quite well, but it was slow. It went drop by drop through the stopper, taking about two minutes to fill half a cup. I think it went through very slowly because of the sand and gravel, but I think it worked well because of the wipe that took all the dirty particles away, plus the sand and gravel also helped take away dirty particles. After that we added more gravel and sand to the first design, it lightened the color a tiny bit but did nothing else except for slow it down a tiny bit.

Our last design had materials that consisted of a cotton ball, one screen, sand and gravel, and a wipe. We decided to take out one screen because we didn’t really need it and it was broken, also we added the cotton ball because it would take the darkly colored contaminated water and suck some of it up but not too much too make the water lighter and take some particles out. We only put one cotton ball because it would suck up to much water. This design worked better than our first design, the process was much faster but the final product was only a bit better. I think it went faster because we took out one screen and added the cotton ball. There were also no materials in it but the color was lighter which must have gave us a good two! This was a very cool process and I learned that the wipe can take away a lot of dirty particles but soaks up a bit of water, and I also learned that it is hard from keeping some of the sand from going into the water. I also found out the screen’s holes are too big so it can only keep a few big particles out.

Before Our 2nd Luanch

After our 1st launch was amazing but we decided to make some changes. We decided to make changes to the nose cone. For our nose cone we thought there was some air resistance that could have made our rocket go slower but instead we made our nose cone smaller and put glue and duct tape under to stop it. The other changes we made were, we were much more careful with our duct tape so that there were no air pockets in it. Those are our changes to our rocket I hope it works well! and tomorrow we will launch our rocket.

Launch #1


Today October 23 2017 we launched our rockets and there were 5 groups in total. This was a very exciting experience in 5th grade for us. I never knew just with our group we would make a rocket that actually would fly very high.

We created our water bottle rocket with a bottle, duct tape, hot glue, a 3D printed nose cone, and balsa wood for fins. We used the bottle as the base, and then hot glued the balsa wood with duct tape on. After that we put some decorative duct tape on to make it look nice. After a few days we printed our nose cone and hot glued it on. When I saw the rocket I felt proud of myself and my group.

We each had jobs inside our groups and also outside our group. Each group helped another group for jobs. Doing this was very exciting, each of us had to help another group, some of us were clinometer readers and some were data recorders.

For our launch we went to the back of heathcote which is the field. The Blasting Rockets got to go first, The Rocketeers went second, L.A.S.A. went third, we went next, and last of all J.E.X.L. I was very surprised when we launched our rocket, It went really high and it was very intriguing.

When we got back we started doing data analysis. We found the height in meters for how high our rockets went. According to the data, today in rocketry J.E.X.L launched the highest rocket at 57.5m high and Blasting Rockets launched the lowest at around 20m high. The height difference between the two were 37.5m. My group Science Minds with me, Mia, Om, and samantha, launched the second highest; our rocket launched at about 51m high.

When we revised I thought about how we could improve our rocket. I saw other groups rockets and saw that some were longer, some were bigger in width, and some were smaller in width. I wondered what could we do to improve it. Our group talked, when we were talking we realized that at the nose cone there could have been some air resistance. Me and Om thought that making our nose cone smaller, so it could fit right into the rocket and stop the air resistance. We haven’t decided which way we should use it yet, but Mia and Samantha want to stop the air resistance by just putting hot glue under it. I wonder if me and Om’s plan will actually work and I wonder if we make our rocket skinnier if it will go faster up.
