This week we focused a lot on forces primarily gravity. We did this through an experiment with dropping eggs from 1 meter. We built bowls with materials we thought would cushion the blow of the egg's landing. We at first built our bowls with sand, hay, and rubber turf but our first egg broke on impact with the turf so we tried it again with more grass and no turf. This time it landed without cracking however, the egg did bounce out onto the floor. Like, I said it did not break then, but the egg broke when we did this same experiment from 2 meters high.  Moreover, we also learned about how essential graphs are for analyzing data as it is easier to notice patterns with graphs. Additionally, we learned how useful bar graphs are for lower elementary.  A description of what you learned in Thursday's lecture: No Lecture. We had our physics exam.

  The big question addressed in lab, and a description of what you did. In lab, we learned about pendulums and the science behind them. We did this by building our own pendulums with a pencil, string, and a paper clip. Then we tested how many swings we got with different weights and learned that the weight of the pendulum does not affect the speed. We also talked about the science of the wild, and personal development, and did an experiment with mixing colored water. We did the color wheel to teach students how to do experiments.  A description of what you learned in Thursday's lecture. In Thursday's lecture, we learned more about pendulums and learned why the weight of it does not affect the speed. The weight does not matter, because while a heavier mass will pull more on gravity bigger masses are harder to accelerate and therefore the two effects cancel each other out and make weight irrelevant to the speed of the swing. We also talked mor...

  The big question addressed in lab, and a description of what you did. In lab, we tested different factors like slope, weight, clothing, and others that could change how fat one goes down a slide. My group decided to test how clothing impacts speed. We felt that thinner material would cause a person or object to go faster down the slide, but that no clothing would go the slowest. We found out that we were right. A description of what you learned in Thursday's lecture.  In the lecture, we learned about gravity and forces like friction. We were not all knowledgeable about the subject but then had a discussion and learned much more about how friction works. One example that stuck out to me was how a magnetic force will act against a gravity force. Like for instance, when I tried to use a magnet to put my roommate's calendar on the fridge the forces of the magnet and gravity were fighting with each other. However, in this case, gravity won because even two of our magnets together...
