RAMP AND BALL,
CONTROLLED STUDY
LAB REPORT
By Hayley, Aiden, and
Connor
Problem:
Our problem
statement
was……
How does the
release distance
affect the
bounce of a golf
ball from
bounce 1 to
bounce 2?
Hypothesis:
Our hypothesis
was….
I predict that the
release distance
of the golf ball will
make the ball
bounce further
from bounce 1 to
bounce 2.
Controlled
Variables:
Our controlled
variable was…
-Golf ball
-PVC piping
-Angle of Ramp
Manipulated
Variable:
Our manipulated
variables was:
-Release point
-Distance ball bounces
Dependent
Variable:
Our dependent
variable was….
The distance in
centimeters from
bounce 1 to bounce 2.
Materials:
Our materials
were….
-Carbon Paper
-Goggles
-Golf Balls
-Graph Paper
-Lab Report
-Masking Tape
-Meter Tape
-Scott Towels
-16D Nails
-2 PVC Piping
Procedures:
For this
experiment, we
followed these
steps…

9.
Draw a diagram.
Write procedure.
Gather materials.
Construct model ramp on
chair.
Measure distance of PVC
piping from floor.
Place nail at first point.
Drop ball then release nail.
Measure distance from
bounce 1 to bounce 2.
Record observation and
data.
Observations:
Our observations
during this
experiment was…..
Drop 1: Dropped 44cm away from
each other, didn’t bounce to far
apart.
Drop 2: The second drop was farther
apart, probably because of the
height.
Drop 3: The ball is starting to go
faster.
Drop 4: Again, it bounced father
away, we needed to add another
piece of paper towel.
Drop 5: It bounced very far away
from each other.
Drop:6 The last drop was definitely
affected by the height of the release
distance.

Release Distance (cm)
Possible
Explanations:
Some possible
explanations are….
One possible
explanation is the
release distance that the
ball took of at. Another
possible explanation is
the angle that the PVC
pipe was balanced on.
Conclusion:
My conclusions
were….
The height of the release
distance from bounce 1 to
bounce 2 is effected by the
release distance.
If you release the ball from
a tall height, the faster it
will go down the ramp.
Having a higher release
distance gives the ball
more time to pick up
speed.
