I finally try a lab that I found and purposed on my own. It was not a crazy lab like making a lava lamp, but still a big step. The lab required: Orange(s), olive oil(full), lighter(of some kind) and a knife. For the first step was to cut into the orange in the middle along the side, but only throw the skin. Then I had to carefully carve out the orange fruit to make sure leave the stem in tacked. Then I cut a hole on the top half of the orange peal to make a shield to protect the flame. Then I pored the olive oil into the orange peel and made sure to cover the stem(wick). I have forgotten to let it sit for 2-3 minutes, so when I went to light it, it didn't burn too well, also I poured to much olive oil into the candle so there was little to start with. Even so, I manged to get it lit for about 30 seconds which made it all worth it. I also did a bunch of research to understand the lab. The first thing I researched was how candles worked. The wax is to fuel the flame, the wick is where the flame will be, then the combination of the wax and the flame burns and steam and burned carbon comes out which makes the black spots from candles. I wasn't sure at first how much I would learn but I really enjoyed learning how candles worked. I felt proud when I saw the flame on my orange stem. Then I found the definition of combustion which is when compound and an oxidant which means that there needs to be a full, some form of O(oxygen) and some form of an energy start. Hey Halloween is coming up soon, maybe I can use this to make fake little jack-o-lanterns! I know next time that I need to let it sit for a few minutes so that the flame will stay lit. I'm also curious to try this experiment with other fruit to see if it will work.
The drawing above is a illustration of the sates of matter. The wolves are the gas, deer(river) is liquid and the trees are the solid.
I wasn't sure how this was going to turn out and I was worried that I would look really bad. I guess it turned out good and it was really fun to play with making the trees and animals into elements. I feel like maybe I could have more and maybe better with the color. This experiment we did was mostly for the teacher to tell if we could be trusted to be able to do work with labs. Over all ever one that I was working with and my self had loads of fun and nothing bad happen while working with the dry ice. I loved pushing and sliding the ice on the table. At one point we put the dry ice in to a beaker with water and bubble mix to make what you see above. The main or required part was where we needed to get a chunk of dry ice about 2 cubic centimeters, get into a balloon and after it melted, measure the balloon to find the value of the dry ice. We got the measurement but only at the end of class so we didn't have time to do the equation.
For this experiment my group, Sammy, Annika, Kazhu, Melany, Ashleigh and I mix corn starch and water to make a sustains called oobleck. A first we had a good balance between the corn starch and water. Which when we applied pressure it hardened and cracked. Then we added to much water and could not get it back. At one point one of the teachers slamed a hammer into the oobleck and the hammer just bounced off it. I then tried it and got stuck in the oobleck. He said that I needed to hit it will all I got, but at last second I doubted smashing it down in fear of missing and hitting the table intended. On a more scientific note, it responded a lot to pressure. When ever we added pressure it crumple and cracked. Then when we let go it liquefied. Depending on the pressure that is being applied, oobleck will crumble or drip. More pressure, the more it crumbles. The less pressure, the more of a liquid it will be. Wile I was working with the others, It was mostly a free for all where ever one was playing with it and we all where just playing with what we could. It was a little too crowded and every one was trying to play with the oobleck. I didn't do much except get yelled at for a personal ocd. If i was to do this lab again I would have more containers for smaller groups so that there is more to go around so every one is not pushing to play with it. I also would work again with most of the people but few I would not like to work with again.
