Engineering
For my seventh period I have Engineering with Mr. West. engineering is really fun because, we get to build cars, make slide show presentations, and do a whole bunch of other cool stuff.
In engineering we are making sleds called Newton Sleds. To make one you get a piece of wood that is about six inches long and three inches wide, put three screws in it (=- like this), put a rubber band around the two in the front, pull it back with a string, wrap the string around the screw in the back, put the "sled" on about twenty dowels (small circular pieces of wood about three inches long) spaced about an inch apart, put a block of wood about three inches x one inch x two inches between the two long pieces of rubber band that were pulled back to the back screw then burn the string to release the rubber band holding the block of wood.
We all got a partner and did this. After we lit the string on fire we, apparently, didn't make sure that the match and string weren't still hot when we put them in the trash can, and it lit the trash can on fire so it melted. Mr. West showed us a picture today of the trash can and it was all melted and burnt... It was kind of funny yet scary that that was in the same class room that I was in when he told us what had happened.
So moral of the story make sure that the match and string that you lit on fire are out before you put them in the trashcan.

In engineering class, we made lego cars. These cars had to pull at least 400 grams of weight and itself. This was a very big challenge, because this meant that I would have to work very hard long "hours" to finish this in time foe the due date.
Usually the cars would not look as good as this one does. When you make a car, there is this concept of gear trains. this is when there are gears driving other gears. |
