Marble Run

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 into 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. In my group was AJ, Autumn and Zara.
