First we drew out the plans of building bridges. Next we got the supplies that would be needed in building the bridges. Next we got to work on the bridges and build the platforms of the bridges. After the bridges were built we typed out all the stuff that would have tp be typed out before we tested the bridges. After that we tested the bridges by putting weights on them. After the testing was done we wrote down which bridge was the strongest and which bridge was the weakest and why they were that way. In our spare time we drew pictures and set up the back drop for the project. That is the procedure for our Science Fair Project.
