Title
Distance of ball

Problem Scenario
the catupult will brake

Broad Question

 * how far will a smooth ball go than than spiked ball **

Specific Question

 * Dose the smooth ball go farther. **

Hypothesis

 * The smooth **** ball will **
 * go farther than the spiked ball **

Independent Variable:

 * distance dependent **

Dependent Variable:

 * type of ball independent **

Vocabulary List That Needs Explanation
ball,distance and catapult

General Plan
Iam going to lanch the balls frome the catapult and record the data and make the graph

Potential Problems And Solutions
the balls will not launch.make big catapult with small springs

Safety Or Environmental Concerns
catapult brakes or spring's will snap

Experimental Design
(add the correct headings from the experimental design page before beginning)

What is your experimental unit?
This is the base unit of your experiment, for example, one plant, one ice cube, one dish. It is the thing you will be measuring.

Number Of Trials:
This is how many times you will repeat the experiment. I will repeat the trial 5 times for both of the balls.

Number Of Subjects In Each trial:
This is the number of different treatments you will use. For example, if you are comparing rust formation using salt and no salt, there would be 2 subjects in each trial. If you were comparing rust formation with no salt and three different amounts of salt, then you would have 4 subjects in each trial. Their is 2 in the experiment one smooth ball and one spiked ball

Number of Observations:
How many measurements will you take for each experimental unit times the number or trials.Their will be 10 trials 5 smooth and 5 spiked.

When data will be collected
Looking for an actual date or dates here. This is requiring you to commit to your project.The day I do the experiment.

Where will data be collected?:
Be specific. The data will be collected in a Google spread sheet.

Conclusion
I accept my hypotheses because what I said worked

Benefit to Community and/or Science
this can show kids history is fun and educational and how to be safe with science. **Background Research** The catapult was used in mid evil times to get big and far hits on the targets. **References:** Thadani, Rahul. //Buzzle.com //. Buzzle.com, 10 Nov. 2012. Web. 21 Mar. 2013.
