Recently, in Te Ngahere we did The Great Marble Challenge Take #2. Just like what’s said in the title, this time it was a redo of the challenge. If you didn’t know already The Great Marble Challenge is when groups design a ramp for a marble to roll down. The goal is to get the marble to stop at exactly 110 cm. Every ramp gets ten tries to hit 110 cm. On competition day the group who made their ramp will hand theirs over to another group to operate, while only using written instructions. The ramp group will be unable to communicate or interfere when the ramp is being used on competition day.
This time we got 21 points in total, and we got one 5 (within 1.1 cm of 110cm). The major change of my groups ramp was the materials that we used. Instead of cardboard and paper, it was changed to sturdier ones. We used a ruler instead of paper towel tubes. It was a really successful change because it prevented the slide from being damaged.
Something we could’ve done better was our time management. I think we could of evened out the amount of time we spent on the ramp and instructions. I think we could of simplified our instructions, because that lead to the people who tested our ramp overwhelmed and confused.
One thing I enjoyed the most about the marble run was finding out or witnessing a creative way to remove variables.
Here is a drawing of my ramp:
