How A Semi Drives on Different Roads

Morgan And Leslie

Our materials for our science project were a box with a rag and tore up pieces of a clean free sheet taped on to the rag. Also we used a folder with a paper towel taped to it, a box with foil and little bumps of foil taped on to the foil. Also, a folder with cards taped to it. We also used bird food, a cardboard box, a little box, a book, and a folder which the semi slides down. Those were the materials which we used for our science project.
The description of our project is that the folder with nothing on it is taped to the bird food and a folder with paper towel on it is waiting at the end for the semi to drive on it. After you do all that, you put the semi at the top of the blank folder and let it drive down. Then, you change the road after you let the semi drive down. That is a description of our project.
These are the steps we did to do the project. First, you put a road on the plain folder. Next, you put the semi on the top of the plain folder and let it roll down the road. Last, you change the road after the semi drives down it. Those are the steps we did to do our project.
We think you should buy our project because then you know what road is most dangerous. We learned that you can go different speeds one different roads. All in all, that is what we did to do our project.
