We were given several materials such as pins, a board, straws small, medium and large-sized marbles. Using these materials we had to build a track so that the marbles could roll down slowly.
Reflection
1. How well did the marble
stay on its pathway?
The marble stayed on its
path well. It did not roll of the board halfway and completed its route.
2. How well did it turn the
corners?
It turned its corners
quite well too. It did not stop halfway because of barriers.
3. How long did it take the
marble to complete its journey?
It took 3 seconds to
complete its journey.
4. What was its overall speed?
Its overall
speed is 3 seconds
5. What other factors affect
the performance of your marble?
The clay that we used was
sticky, and the pins were used as barriers
6. How might your design be
improved?
We should have used straws
instead of clay becau
se the clay made the board
and the marble sticky. Furthermore, our marble rolled down really quickly as
the clay did not really slow it down. We could also use the pins as barriers to
slow the marble down instead. The size of the marble affected our result as
well. We used the biggest marble provided, hence, it would have the most
kinetic energy and this will cause it to roll down faster.
