Marble roll-Ramp A
In our maths group we dropped the marble to roll down the rivet, (a wooden ramp) or a cardboard ramp (handmade). First we dropped the marble on a special point marked on the ramp. The first point was 45 and we used the rivet. We rolled the marble 4 times and recorded it. We also did that with other marked places, next we drew a scatter graph.
My scatter graph wasn't very good so I borrowed my friends one. I found it hard to challenging to understand, later on it got easier to work. Next our teacher told us to try a website of scatter graphs online.
I found that the scatter graphs online were better than in making it. I was confused in the beginning but after a few trials, it was simple. After all this I had to analyze it. Our teacher told us children, to get past level 4, we have to know how to draw and stack data into scatter graphs and line graphs.
