OUR CANNON
Our Cannon
When we first started working on our cannon we first though of a design. We each began looking up different cannon designs and angles that we could have the cannon at. The angle we chose had to be perfect; if it was too high then the ball would have more air resistance and if it was too low it wouldn't go its max distance. We all agreed that 45 degrees would be too high so we decided to keep it between 30 and 40 degrees but closer to 30 degrees. After we decided the angle we though about the design; we had to up with one that kept the cannon at the angle we wanted the cannon to be in. We all thought up ideas and began to talk about the pros and cons of each. We all decided to cut a groove in the side of one of the cans and to lay the other can in the groove. We all agreed that the idea would allow our cannon to be most successful in shooting. After that we began building. As we began to build and put everything together we saw that our cannon might just work and then we began to believe that ours could actually launch the furthest.

Here we are thinking about how we should design our cannon
Putting down ideas on what our cannon should look like
Here we are seeing what angle would be best for our cannon
Here we are seeing how our design would look
Listening to teacher tell us more about the project
Beginning to work on our design
Picture of our design that we chose
Our beginning materials
- Scissors
- Two tennis ball cups and tops
- Protractor
We start building after thinking about a design
Our design beginning to come together
Still building, TRYING to poke a hole in the bottom of the cup

Our finished cannon with everything in place.
