PROJECT SUMMARY
We made a catapult that can go as far as possible. Our catapult has the power to throw far. And also we have techniche for it. Our problem was the wood was too weak then we upgraded and taped the wood to get stronger.
WHY?
I do this project because I wanted to show how amazing is the catapult. We want to show how this machines makes the ball goes far.
HOW?
We create by colaborate and helping each others, we bring matrials from classroom.
WHAT?
Our prototype work by bringing forces from pushing the rubber band, then It brings really big forces to throw the rock or ball far away.
SO WHAT?
i think our result is important because we can know how our prototype is working by test the force of it. I learn that the important of connection, connecting the catapult and the rubber band is like adding parts of it and complete the work.
WHAT'S NEXT?
Maybe upgrading parts of the prototype, like make it stronger the wood. But I also think I don't need any upgrade for our work.
REFERENCES & ACKNOWLEDGMENTS
i got ideas by searching in youtube or google, the lenght of the materials we find it by comparing the other materials.
JUDGES FEEDBACK
This is a very nice prototype of a catapult and it seems like you spent some time trying to improve its design an ultimately effectiveness. It would be nice it you added a video to be able to see it in action.
