FUN TIMES WITH YOUR DOG

BY JACOB SCHULDHEISZ

What Makes playing fetch with your dog much more fun?

• A catapult will be the solution for this problem because everybody loves launching a tennis ball.

• Or some other kind of machine that will launch it like an airsoft canon.

Why did I choose this project?

• I have two dogs and I atleast have to play fetch with them twice a day.

• Somedays my arm is soar from baseball

• The dogs never get tired and so I can make them tired this way

• My brothers and sister would want to play fetch too.

what I enjoyed most

• Working with my Grandpa

• Learning how to use different tools

• Launching the tennis ball for my dogs

How to launch the catapult.

• Get a normal sized tennis ball

• put it in the ball in the yellow bowl

• pull back on the hand of the catapult

• make sure the dogs are not in the way

• release the hand.

• the ball should go a distance of about 120 ft.

problems encountered

• We got the measurements of an angle for the 2x4 piece of wood wrong three time.

My ipad got hit by the hand of the catapult when I was taking a video.

Results

What I learned from this activity

• Launching a catapult is a lot of fun

• The dogs got tired much quicker

• Surgical tubing is very strong

• My brothas n sistas loved it too

Things I would do differently next time

• make my catapult much smaller

• Add more weight to the base of the catapult so it doesn't rise off the ground when launched

• make it launch farther because I think it would be more fun

The most difficult/challenging aspect of my project.

• building the catapult one day at a time.

I wanted to just get it built so can start on my

reports
