Hi, for the past few weeks we have been doing something called the great marble challenge. We had to build a structure that would make a marble go 1.1m. I was in a group with George and Mark. We were quite unsure about what to do so we decided to brainstorm for a long time. Eventually we came up with what to do. We decided to use my chromebook and then stack a tube on top of it. Finally we decided to get some cardboard and attach it underneath the tube. We were doing this to learn how to follow the scientific method and to help us prepare for science fair that is coming up soon.
When we had finished building we moved onto testing. We rolled the marble down for the first time and it was very off our goal. We modified it and added Mark’s chromebook underneath as well. From there on we tested and modified. Most of them were changing the angle up and down. When we finally thought we had got it right we wrote down our instructions. The next day was competition day and we were happy with what we had done until it got to our turn. Someone else from another group had to read our instructions and then test our marble run. When he read out our instructions we realized something was terribly wrong. Only half of our instructions were on the paper. We were dumbfounded because we only got nine points out of 50. The hardest part about this project was coming up with the design and building it because we needed to measure how long we wanted our supplies. The easiest bit was writing the instructions because we had already tested how to do it so many times.
Have you ever made your own marble run?
Kia ora Jacob,

Kia ora Jacob it´s Nikau from Ahipara school. I really liked how you have described what you had to do for this marble challenge, it seems like it was a lot of fun. Keep up the good work and blog ya later.
