On Tuesday, my group and I, made a marble run. We got into groups of 3 or 4. We had boxes that we used for the base of our marble run. We did it for learning about forces and motion. The class had to get near 20 secs. Are time was 3.58 secsonds.
\I liked working together and having each idea going into our marble run.
I found it quite challenging when we didn't agree with most of the things. Next time I would make it bigger.
