I' The Density Lab was all about buoyancy and how helium weighs less than air and because of density lighter things go up and more dense things go down. In this Experiment we were seeing if we could measure how much helium was in a balloon by putting the balloon at neutral buoyancy and knowing the difference between the mass of helium and air. So the question is can we find out how much helium was in the balloon?
The experiment went well but first we had to learn some background information. Density is mass over volume or grams over milliliters and with, also that buoyancy is the level to which two substances densities match. So knowing this we filled a balloon with helium and put tape on the balloon to get it to neutral buoyancy and after we got it to neutral buoyancy we popped the balloon and weighed it. Knowing how much the balloon weighs and the mass of air we subtracted the mass of the balloon by the mass of air. Then we divided it by 2572.15 cm cubed, then we found how much helium was in the balloon which was .001225g over cm cubed.
I learned from this experience that in math and science having one thing or piece of information can help you find the missing piece of the puzzle. This applies to most everything really, in real life investigators can take blood, descriptions, and fingerprints to narrow down a suspect. Along the way I realized you can measure helium, air and a lot of things knowing bits and pieces of information. Also with this fun experiment I gained some knowledge about measurements and how scientists are just measure-rs and also are investigators.
During this lab it was very guided work, which guided work is nice because the person teaching will always get the right point across, but I enjoy more hands on work with some guidance. I really like making things and discovering things on my own, but it is also useful to have help available, I'm not completely independent.
This information is useful for the rest of chemistry, some of math, but mostly useful for understanding that everything natural is interconnected and that this Earth is amazing because of that. I think I could take this further by conducting it with something heavier than air maybe.
