• Does (x) have an effect on (y)?

OR

• What is the effect of (x) on (y)?

OR

• If I change (x) will it effect (y)?

What is the effect of the height of a ramp (3.5cm, 7.0cm, and 10.5cm high) on the distance a “Hot Wheels” car will travel in centimeters from the bottom end of the ramp?

• Research: Important facts about the topic.

• Use scientific words.

• What is your reason for doing this experiment?

• What information did you get from your research?

Manipulated Variable: (x) The ONE

Responding Variable: (y)

The height of the ramp – 3.5cm, 7.0cm, 10.5cm

The distance the car travels in centimeters from the bottom of the ramp to the back wheels of the car.

• The height of the ramp will have no effect on the distance the car will roll.

• The higher the ramp, the farther the car will roll.

• The higher the ramp, the shorter distance the car will roll.

List all possible results

• The prediction you think will be the result and why.

I think that the car will roll farther when the ramp is raised higher because I know that my bicycle and wagon go faster when I ride down a hill or down the steepest part of my driveway.

Constant Variable (Set up conditions)

• The same car will be used in order to keep the weight and wheel conditions constant.

• The same ramp to keep the length and surface constant.

• The starting position of the car will remain the same.

• The location in which the experiment is conducted will remain the same.

• Each material with description of number, size, amount, kind, and how each is used. Use metrics.

• (1)Hot Wheels Car

• (3)Blocks of wood (3.5cm thick)

• Meter Stick

• Ramp (100cm long)

Detailed directions that another person should be able to use to do your project the same way that you did it and get similar results.

• Gather all materials together.

• Select a smooth rolling surface to roll the car on (counter, table, floor).

• Place one of the 3.5cm blocks at end of the ramp.

• Place one end of the ramp on top of the 3.5cm block and aim the bottom toward the end of the rolling area.

• Place the “0” end of the meter stick at the bottom end of the ramp.

• Place the rear wheels of the car at the top of the ramp and release it to roll down the ramp.

• Measure the distance it rolled from the end of the ramp to the back wheels and write distance on data chart.

• Do this 10 times.

• Place one of the 3.5cm blocks on top of the other 3.5cm block creating a height of 7cm.

• Place the third 3.5cm block on top of the other two blocks making height of 10.5cm.

• Find the mean (average) of distance recorded.

Results of the ramp.

• Describe what happened in the experiment using the data from your chart.

The data shows that the car rolls almost

twice as far each time the ramp height is

raised. The average distance at 2cm high

was 22.5cm, at 4cm high it traveled

43.2cm, and at 6cm high it averaged

91.4cm.

Conclusion of the ramp.

• This statement tells why the results happened in your experiment

The results supported my hypothesis.

The higher you raise the ramp, the

faster and farther the car travels.

Real World Uses of the ramp.

• This statement explains who in the real

world might use this information, ways

they might use it, when, where, why,

or how they might use this information.

List at least 3 ways if possible.

Reflection of the ramp.

• How I liked doing the project.

• What would I do differently.

• What new questions did this project present?
