Lithium Used in Battery Display.
There was an exhibit when you can spin a disk and observe how the balls in the bowl move. One of the balls is grey, the rest are orange. Upon spinning, there was no clear difference between the grey ball and orange balls.
Lithium is likely a good metal for a battery, due to its low atomic mass, which allows it to move faster, allowing it to transmit electricity better. Still no idea about how battery works.
When creating exhibits/experiments, one must make sure that the idea/concept/ purpose is communicated clearly. One needs to have a greater understanding of the elements and compounds in order to better understand our resources, which we can use to solve world life problems.
Day 2
During the process of trying to observe a cell sample, I had trouble seeing anything. It was only after the magnification is reduced, then could the sea anemone be seen. The reason that this happen because we zoomed in so much we can’t see anything too much. Sometimes we need to take a step back and look at the big issue when solving problems, to change perspective (+ Do not be a microscope, and look at the small issues. Look at the big issues). Start with big picture, look at the big issue. Understand the context
Day 3
While trying to record a video of the TissueLyser shaking the cells, I noticed an interesting phenomena. In my eyes, when I looked at the camera, it was shaking so fast, it just looked like it was vibrating violently. When I looked through a camera though, the up and down motions of the machine were more obvious through a camera. This likely happened for a few reasons. Firstly, video recorders work by playing taking many photos back to back. When a video is played back, likely many photos are taken which are then played back to back to create motion. What likely happened was that 1) the camera wasn't able to keep up with the motion that created the error, 2) the phone didn't have the ability to play all the frames at the right speed. From this, we can conclude that there are limitations to the human eye/cameras which can affect the accuracy of our judgement. Use a camera with higher quality/more frames per second (such as high speed motion capture), in order to have better analysis, when capturing high speed event
Day 4
When going to the beach to look at corals, with what knowledge I had learned, I realised that what look liked a rocky beach was instead a beach that used to be underwater and was populated with corals. The reason that there were these corals was was because when the corals were growing, they formed a calcium carbonate as a shell. After the sea receded and the corals died, all that was left was the shell. From the situation, I learnt that we should keep better look at our surroundings, to be observant and attentive, that way we can realise the interesting things that are in front of our eyes. When walking, I learn to pay attention to small things like a snail or a leaf and wonder about things.
Day 5
While we were walking through the aquarium, a phenomenon that I noticed was that my shirt started glowing red under the UV light. Upon further research, I discovered that that the reason certain things glows in the dark is because they contain phosphors. The phosphor substance then glow in the dark, creating the effect. This means my shirt, as well as some white shirts contain phosphors. From this, I have learnt that different substances can react differently under light, for example, wearing yellow sunglasses causes uv light to appear green. Phosphor can be used to mark objects, allowing for identification depending on the situation.
Day 6
During the visit to see preserved specimens, I saw an enormous fish called a oarfish, that had been preserved. It was very long, at least longer than half the room. It surprised me that a fish this long and flat existed. Furthermore the fish could actually said to swim similar to a razor fish, except with its head facing up. Although I do not know why the fish is like this, it is still amazing to me. It surprised me as I did not realise something this big and ridiculous existed. Not to mention the fact that I learnt that such a long fish would swim in such a strange manner as to be positioned vertically. The world is big and vast, and all kinds of strange scenes can be seen, especially in something as unknown as the ocean. I should do more research and read up on a variety of books, and keep my eyes open while travelling, in order to broaden my horizons and learn more.
