This week, we did a lot of different labs. All of these labs consisted of figuring out mass. The first lab that we did this week was with matches and and scale. We burned the matches on the scale and found out that when we burned them, they lost matter.
On Tuesday, my group did a lab that we had to pour sugar into water and figure out what happened to the mass. I predicted that the mass would be greater because you are putting the sugar into the water. I was correct I the sense that the mass went up, but I wasn't sure why. After other groups presented their experiments, we came to a consensus! it was that:
The mass of the system doesn't change unless matter is added or taken away from the system.
This is a model that we can use to predict future outcomes of experiments.
On the next day, we did another lab. we had to fill up a container full of water, measure the dimensions, and find the volume in cubic cm. Once we did that, we had to pour it into a measuring beaker and figure out how many mL it was and what the relationship of the two were. From this, we figured out that the measured volume=calculated volume, which meant that there is 1 cubic cm for very 1 mL! It was kinda cool that we figured this out on our own and I really enjoy doing labs.
On Friday we measure the volume and mass of these metal blocks. We tried to figure out if there was a relationship between the two. it turns out that there is not. The little red cube had more mass (g) than one of the bigger solve blocks. This proves that theres not as much matter in the longer one and not as much inertia, thus having more mass.
Overall, this week we learned a bunch of different things and made theories that can help us predict the outcome of other expiriments!
