Our motor did pretty well. It lasted a while and the thrust wasn't that strong, but I think we did good and our motor will be good. After testing the motor, we had to figure out our thrust curve from our rocket by watching the video that we recorded. We put it into Adobe Premiere and we put the video and played it 1/30 of a second, frame by frame. It took a while but the results came out good. Jesus and I chose to make this rocket because it seemed like a good design for us. We both liked the motor and we were ready to test it. We chose an end burner core with a 3/16" nozzle. We used black powder because we thought it was going to turn out good. We named our rocket "The Resurrection" because Jesus is my partner.
Purpose:
The purpose of this experiment was to learn more about Earth science. To also learn about silicate, how it works and where is it found. We talked about the earth's core and levels of the earth. We talked about the magnetic field and how Mars use to to have one but it was stripped by the solar waves, Also we learned about silicate and how it mixes with metal. With mixing it with metal, elements that are further react first. We were also told that the periodic table does not need to be memorized you just need to know how to read it. Core- solid iron and nickle Outer core- Liquid iron and nickle Mantle- Molten rock (silicates) Crust- outer solid mantel 95% of Earths crust is 97% made out of silicates.Making the rocks there was a combination of silicon and oxygen. What Happened? This was so amazing to me because it how the colors were changing form. They looked like veins kind of. The way they spread right as they were poured in was very cool. It made me very interested the way Andrew was talking about it. Results: The first test tube it look like a spider web kind of. Same with the second. It was different with the second test tube it started of as a red blotches then pink and blue started to grow this is the one that looked like a vein to me, but I wonder what it would look like in a bigger container. The third test tube nothing happened, it was boring I tried to look closely but still nothing was going on. Looking Forward: Looking forward I would like to do this experiment again but in a bigger container. To see how big it can actually grow and compare the first two and to see what was really happening with the third one. Also, I would want to try to make different silicates so it wouldn't be just doing the same ones over and over again. For this guided activity we learned how to make H2O with combustion. A chemical reaction which we figures out is a change of matter where the atoms in one or more substance combine, separate, or rearrange to form one or more new substance. Also focused on atoms and how to tell how many electrons it has by the numbers they have which is shown on the periodic table. While doing a lab you can mix atoms which will combine the two atoms electrons together which will fill the outer shell. The main reason of the lab is to make H2O with a combustion reaction so the substance combine with oxygen to produce water and CO2 so we had
H+H+O -> H2O (2H2+O2 ->2H2O). To see this reaction with our eyes we used Citric Acid and pieces of magnesium and combine them to together with water as well. Once the magnesium was in the flask we had to hurry up and wrap a balloon on top of the opening to seal it. The first thing we noticed that change is the magnesium made the liquid start to bubble and the temperature change getting pretty hot. While this was happening the balloon on top was inflating. Once it had inflated and the magnesium melted we tied it off and the air inside the balloon is lighter than helium so it would float up. We then taped the balloon onto a table setting it on fire and it exploded we watched the flames. This is my two week plan for the final two weeks of the section. I hope to do a lot of small projects, and I hope that I get my blog posted with everything in time for the end of the section so I am not rushing to get all my stuff done at the last second like last section. The 2 week plans are very helpful to me. I am glad that I have started to do them.
