Mouse+Trap+Project+HS

Day 1: Day 2: We had a substitute which made the computers unavailable for research. so we thought of a pulley system all by ourselfs. Day 3 and 4: absent Day 5: i worked on the launcher as tyler and devon worked on the car. i made the launcher by attaching a pencil to the mouse trap. and then a roll of tape to the end to hold the ping pong ball

Day 6: today we focused mainly on our launcher. we went to the hall way to test it out. since its not connected to anything yet we had to duck tape it to the ground for stability. we measured out 10 ft and launched a ping pong ball. with every shot the launcher shot to the right. it would go to the 10 foot mark occasionally so we decided to focus on accuracy the following days.



Day 7: We changed the launcher today by putting a spoon as the arm and instead of a pencil. the first couple shots worked well. but after a while the spoon ended up snapping and breaking into pieces. so we went back to the drawing board.

Day 8: We tested our mouse trap car today. the swing arm broke because the rubber bands were pulled to tight. we had to reattached it to the mouse trap. we did so by using a lot of duct tape. since we constructed the arm we had to think of how much rubber bands to use so it wouldnt brake again. we tested this and the car went fast but too far. so we shortened the string but the string got tangled.

Day 9: we had to find out how much string to use today to make the car go 10 meters. after the first test of shorting the string the car still went too far. so again we shortened it more. that seemed to work the first couple test but the after that the metal support began to bend. that would slow down the the large spool. we tried to bend it back but it would still touch the spool and slow it down.

Day 10: We did a lot of testing on the car today. we ran it about 6 or 7 times to have an exact length of string to use during the competition. We were also still thinking of different ways to make a good launcher for the ping pong ball launcher.

Day 11: Today we figured out a good way to use the ping pong ball launcher. We taped a lid from some sort of plastic bottle to the metal snapping of the mouse trap. after many test firing with this new design we came to a decision that this will be our competition launcher. So then we attached the ping pong launcher to the car through bolts and holes the tyler drilled on the mouse trap.

Day 12: Competition day today. We went first on launcher our car 10 meters and we were successful. so we received a perfect score on that. then we went last for the ping pong ball launching part. the top score was 9 and to get all the points we had to beat it. i was the operator for the launcher.

Day 13: Finished up the log books.
