HYPOTHESIS
If we roll a toy car down ramps of different
heights and measure the distance it rolls, then we think the car on the highest ramp will roll the furthest distance.

4. 1 15 HYPOTHESIS The Vote Rolling Rolling 8 reading books ramp
12 reading books ramp 1 15

5. Variables Rolling Rolling Rolling
Independent Variable- The element that we changed:
The height of the ramp by adding more books.
Dependent Variable- The element that was changed
by adding more books:
The distance the car rolled.

7. Procedure Rolling Rolling Rolling With eight books build a ramp.
Roll car down the ramp.
Measure and record distance.
Repeat for a total of 5 trials.
5. Build a 10 book high ramp and repeat steps 2 – 4.
6. Build a 12 book high ramp and repeat steps 2 – 4.

Results
Using our data we collected, with calculators, the total distance of each ramp height, then got an average by dividing the total by the number of trials, five for each height.

This is a movie which defines simple machines and ramps. It also explains why
a ramp is useful and how it works easier.
Force & Motion, Clint Twist, 2006, Bearport Publishing Company
This colorful book discusses force, motion, pushing and pulling. It explains
why it takes less force to move something down a slope.
Force and Motion, 2003, Delta Education
This book describes force, motion, energy, and work. It gives examples of all
simple machines and pictures of these machines at work in our everyday life.
Hands-On Science-Over 40 Fantastic Experiments-Forces and Motion, 2001,
Kingfisher Publications.
This book increased our knowledge about force and motion. Lots of
activities about forces and simple machines are included. Check it out!

15. Conclusion Rolling Rolling Rolling
We noticed that the more books we added to the ramp, the
further the car traveled.
The majority of the class predicted in the hypothesis that the
twelve book ramp would travel the farthest distance. The
fifteen students who voted for the twelve book ramp were
correct.
A ramp is an inclined plane, a simple machine , a tool that uses
force to make work easier.
We believe that the raised height did some of the work and
made it easier for the car to move and move farther.
