In this asctivity we used a device called a vander graph generator, the machine has a spinning piece of fabric that creates static electricity at the top of the device. I learned that static electricity is very powerful and can be created very easily, I learned that it is attracted to the ground so there needs to be an insulator underneath so they the charge stays in the person. I liked the experiment where the paper flew from the table to the hand because it shows the real power of static electricity and it gives me a good visual of what it can do. I think that this activity was good because we got a chance to learn something new while having fun a time at the same time.
In this lab, we had 6 test tubes per group, in each test tube we poured 5ml of starch solution and one drop of iodine. Then we proceeded to add a different type of pop/juice in to each of the test tubes. This is what they looked like before the juices were added.
We poured the drinks in order starting from left to right, the first substance was pure Vitamen C, this substance had no particular smell and was completely clear, after we mixed it in we noticed that the substance turned from blue to clear again. The second substance was blueberry juice, this substance was red and smelled like fruits its daily vitamin C content was 15%, after we poured it in we noticed that the substance got more clear, after some time we noticed that the liquid turned pink. The third substance was strawberry banana juice, this substance was a thick orange substance that smelled like oranges, daily Vitamen C content was 80%, after inserted the substnce turned into a greyish turquoise substance. The fourth substance was 7up, this substance looked like bubbly water and smelled like lemons, 0% vitamin C, after inserted we saw that there was absolutely no change. The fifth substance was iced tea, this substance had a light yellow tint and smelled like lemons, Vitamen C 140%, after inserted we noticed that th substance went completely clear with a very slight blue tint. The sixth and last substance was Blue Gatorade, vitamin C 0%, after inserted the liquid turned slightly clearer. This is a picture after the experiment.
After the experiment we noticed that the more calcium C these substances had, the clearer the liquid got.
We arranged the cards by number of grobles because we saw that every card had a number of grobles which was exactly higher or exactly lower than another card. Also the cards reactions and colours are almost exact when we line them up using grobles. For the Phoregums we placed them between grobles gaps and numbered it and matched the reaction and colour as well as the state to the substance.
I learned that chemistry uses more thinking than I anticipated and that there is always new things that can be learned.
