Our Project in the Science Fair was called Investigating Slopes!
What we needed:
A
Ramp
A
Toy Car
Ramps
with different surfaces
Frame
for holding ramp at different heights
Metre
stick for measuring
How we did it:
1. We put the ramp at the lowest level. We rolled the car down the
ramp.
2.
We measured how far the car traveled.
3.
Next we moved the ramp to the next level.
4. We rolled the car down and measured how far it traveled again.
5. We continued doing this until we used all the levels on the
frame.
Results:
We
found out that:
The
car went faster and traveled further when the ramp was steeper.

Next
we decided to use ramps with different surfaces: carpet, foam, sandpaper,
smooth, rubber.
We
tested each one at level 5 to see which one made the car travel the fastest and
furthest.
Results:
We
found out that:
Smooth
surfaces helped the car to go faster and travel further. Rough surfaces slowed
the car down.
