Last week, we started a measurement lab that we later finished on Monday (8/20/2018). For the lab, we had to do the following things:
- measure the height of the door, width of room, length of paper, width of paper, and thickness of paper
- Find the length, width, height and mass of two different blocks
- calculate the surface area, volume, and density
- compare our results with another student
- find and compare those results using % (percent) difference
By doing all of these things, I was able to see what percent difference looks like in real life. It was cool to see the variation in other groups’ perfect differences and how ours compared. I now also know that there are many different causes of variation in experiments like this one such as the unclear true edge of the books and the different ways that people interpreted the significant figure rules in their calculations.
