Abstract
To do this project i had to do alot of research on the elasticity of a rubber band and how far it stretches or like how was it made and things similar to that. I tried to find out if the speed and distance the ball goes depends on the elasticity of the rubber band your using so if it stretches far the marble/ping pong ball will launch far and if it does stretch that much it wont go far. We started of by simply building the ping pong ball launcher and getting the help of bands. I noticed that the more elasticity of the the band the more farther it goes and the less elasticity it does not go very far. The distance and speed does depend on the elasticity of the rubber band your using.
Purpose
Who would be intrestead? why?
People that are interested in this project would be people who like building things because to make a slingshot it takes time to build because first you have to find the right stick and then you start cutting it then when u got the shape you have to sand it. People that use rubber bands in daily life would be interested in this project because they will find out that rubber bands don't just work to hold up your hair or to keep bags closed they work for other things to.one example is a sling-shot it is a very important part in the sling-shot because it is the thing that has the force to throw things or launch.
History
The rubber band was originated in the 19th century in Europe. The Mesoamerica created and used rubber bands long ago in 1600BCE (source?). The ancient Mayan people used rubber bands for a lot of things like rubber balls. Also rubber bands where used to hold axe heads to their handles and other functions. They have held structures together in earlier days they were used for weapons.
Today they (who?) bind together documents, food, and many other items. The latex for the rubber band was made out of sap of a couple of plants the most common tree that they get the sap from is the rubber tree. The Mayans learned to to mix the rubber sap with the juice from morning glory vines so the rubber wont be as hard and it can be more elastic and durable.
Not until 1845 did the modern rubber band get invented. Two people, Stephen Perry and Jaroslav Jurash, both invented and patented the rubber band in the same year,on the same day. The first mass production of rubber bands was by William Spencer in 1923 in alliance , Ohio (Source?) . They were made in his basement from hems cut from discarded rubber products.

Process
How does a rubber band work in a slingshot?
A rubber band is the most important part to a slingshot because it holds and launches any object you wanna launch. Also the rubber band has to have elastic force. The more the rubber band stretches the better because since the rubber band can expand the it can throw the object farther. But if the rubber band is not that stretchy the object that is being launched is not going to go far because is does not expand far back so its not gonna launch the object far because the rubber band needs to expand far to be launched far. The more the stretchier the better.
Explain projectile motion and trajectory (look this up in your textbook)
Applications
If you understand trajectory, you hit your target better. How can this skill help you while playing Angry Birds or other games? (Research somethint to cite)
Reflection.
While conducting my research, I was surprised to learn that rubber came from trees and that the Mayans used to make balls from the trees. I understood that you need the rubber for the slingshot to power it to launch the stuff. I already knew that rubber contained latex to give it more power. after conducting this experiment i learned that the bands have to be stretchy but not that stretchy to launch an object far away. i enjoyed this project but i wouldnt do it again
(Add one more paragraph: After conducting the experiment, I learned that....)

Glossary (need 10 terms!; abc order; bold when used in research report)
projectile: something thrown
motion: the state in one object's distance from another is changing
elastic; To expand to a certain rate.
velocity; speed in a given direction.
force: a push or pull excerted on an object
Problem:
How far is the marble gonna (use academic language) travel depending on the band you use?
Hypothesis: (use if then format)
Well i think when you launch the marble with the white band its going to go far.
But when you launch the marble with the blue band its not gonna go as far.
Procedure
1.make/choose the body of slingshot
2.buy bands
3.put end of band on stick of slingshot
4.tie it with Electrical l tape
5.put the object holder on closing end of band
6. have fun!
Material
1 White band
Pipe for the body
Electrical tape

4 marbles
1 Blue band
