  miniature golf

in this assignment we had to make a miniature golf hole and it had to have a theme the one we use was chess. the whole class all made one hole then we combined them to make one big miniature golf course and we played one big game of golf with marbles the next week.

chess pieces

for this assignment we made chess pieces everyone in the class chose from a bag that told you if you where on the dark side and light side the dark side he dipped in acid to make it darker also you drew for the piece you get I got the pawn. we melted metal then pored it into the mold that we bought and then let it harden. the next week we played one huge game of chess with all are piece.

mouse trap car

the mouse trap car was the funniest but hardest one of the assignments we had. we had to make a car move by using a mouse trap as you can see in the picture the fishing pole was attached to the mouse trap and at the other end was a string that wrapped around the axial on the back while this making the wheel spin ours did not work because the friction on the back wheel was not enough with the cd wheels so we used a Toyota toy car wheel. the one we made only went 15 meters.

    catapult

the assignment for this project was to make a catapult or a trebuchet. we did not have enough time so we made a catapult it did not work at all it kept thronging the ball that we shot straight down so we but up a peace of wood that stopped the axis the made it fling. the next week we had a competition to shot the ball into a bucket  from different distance of the room.

 dart

the dart I don't have a picture because I still have not finished it because we are working on them at the same time of the site I hope to be able to but the picture up soon. but for this assignment we had to make a dart for the game darts we but a peace of wood in the lath the spins the wood around and we carve it then we but wax on it then we but the parts of the dart on. we are going to have a game of darts after Christmas break.

co2 cars

for this assignment we had to carve and make a car that looks a lot like the wood cars you make for boy scouts. but the difference is we had to make a co2 car with a drag of under a 1000 we got the one we made to about 350 or so if I can remember right. are time was 50 meters in 4.8sec. they way we got the car to go forward was we but a co2 cartridge in the back of the car and pinned a hole in it.
