We had to build a toy bridge. We had to build it for our final grade in math class. We are working in a group of 5. We are working with people in our math class we also got picked random. The bridge needs to have three things to past as a good bridge. The first one is it has to be light weight, the second is it can hold weight on top of it. The last one is it has to be "30" inch long. One good thing is that we can use any thing on the list of materials that Mr.C gave us. We can also use other things that Mr.C says we can use, but the coast is to much. The list only has 8 things that we can use.
The first is toothpicks that coast 1,500, spaghetti that coast 3,000, popsicle sticks 7,500, hot glue gun that coast 2000,00o. We also had Elmer's glue that coast 60,000, tape that coast 750,000, string yarn that coast 5,000 per yard, the last thing is pipe cleaner that coast 10.000. We only got 1.5m. We had to waste ever thing and we could not go over the budget. If we did go over we would get a 1.
We only bought 172 popsicle sticks. We also bought a glue gun, and 1 pipe cleaner. We first multiple ever thing we have more of, the only thing was the popsicle sticks. then what we got we subtracted what we got. Then we subtracted it from the total coast of the glue gun. We just has money to buy one more pipe cleaner.
The way my group chose our bridge were in two ways. The first thing we did was we each draw a bridge the way we wanted it to look like. Then the way we choose it was that we looked at who had the best sketch and the best one would be the winner and we would do that bridge. The reason we choose our bridge was that the sketch had a lot of detail of the way it was going to be. It also look like it could hold a lot of weight on it and it could win for our group. The type of bridge we did was a Trust bridge. We are building it because this bridges are meant to hold weight, so we thought it would hold up the weight we are going to put on it.
The way we fond our bridge was we saw it in class and we wanted to do it, but in a different way. Then we also saw it in the web. We had to draw it and show how it would hold the weight. It also has to show the force of the weight.We bought popsicle sticks because it is the strongest thing he had. We just bought the pipe cleaner to waste all the $. In our group we all doing the same thing. We all gluing the bridge together. We are sharing the project. This is what we are doing in math class
