Marble Challenge

In Te Ngahere we have been building marble ramps. We were learning about variables and friction. A variable is something you change to improve something or make it worse in a scientific test. Friction is created from the surface, If you have a smooth surface your marble will go fast but if it is bumpy it will go slower. We had to try and get a marble to exactly 110 cm from the ramp. The first thing we did was get in to a group of three. Then we gathered things from around the classroom to use for our ramp. After that we assembled our ramps with the equipment. After we assembled our ramps we put a marble on the top of the ramp then released the marble to see how far it would go we did this 10 times. After we tested it 10 times we changed a variable Then we tested the modified ramp ten more times. We Kept doing this till we found the design that was closest to 110 cm. We then had to write precise instructions to give to another group so they can build the ramp on the testing day. Last Friday we had the testing day. Our names were drawn out of 2 boxes one group designed the ramp and the other had to follow the instructions to build it. We learned that it was really important to right clear and precise instructions. The winning was designed by Missy Emma and Cheyenne, their ramp was built by Isabella-paige and Mikaila.
