![]() ![]() This simulates how real cars and people are spread out along the length of a bridge. One at a time, keep adding pennies along the length of the bridge. Place a penny in the middle of the bridge. ![]() By folding the paper into different shapes, you can make a much stronger bridge, even though you did not add more material. Use tape to hold the edges in place, to prevent the bridge from unfolding. A flat piece of paper is very easy to bend, so it makes a very poor bridge. I highly recommend the q tip bridge for a fun engineering challenge for elementary kids in the classroom or at home. This is what you discovered when building a bridge out of a single sheet of paper in this project. Alternatively, given a limited amount of material, you can make it very strong depending on how you shape it. This makes them more lightweight and less expensive, since less material is required. Most of the metal beams that support them have hollow cross-sectional shapes like circles, squares, or letters like "C," "U," or " I." These beams are very resistant to bending, but require far less material than a completely solid beam. Fun Bridge Your Bridge Club and transparent png images free download. Engineers take advantage of this fact when building bridges or other large structures. Use a second large paperclip to hang the load tester over the bridge deck. Poke the ends of the paperclip into opposite sides of a paper cup, just below the thick rim at the top. It is much easier to bend one way than the other! In general, the shape of a material can dramatically affect its strength. Set up a fun science and engineering activity for kids using everyday materials to construct a bridge together Make it into a challenge to see how much weight the bridge can carry and compare results using different methods and materials. Make a load tester for your bridge by unbending a large paperclip into a V-shape. Assorted building supplies like egg cartons, plastic cups, toilet paper tubes, cardboard, straws, pipe cleaners and popsicle sticks. Construction paper in various colors, including brown for the bridge itself and blue to incorporate as the water below the bridge. Have you ever tried bending a ruler? If so, you probably bent it in the "thin" dimension and not the "thick" dimension. Tape, glue and paper clips to hold pieces of the bridge together.
