![]() Test the paper bridge design by adding pennies to see how many you can add before the bridge has structural issues. ![]() The ends were slightly pinched to create an oval for more stability. Folds on each side to establish an approximately inch high edge so that it is a folded rectangle. Take a piece of construction paper and fold the sides down and back on itself so that it is still 11 inches long, but that the width of the paper can be taped together. If you looked at the end of the bridge design, it would be flat on the bottom and concave on the top. ![]() It gets its name from what the ends of the bridge look like. Next let’s make a folded collapsed oval bridge design. #2 – How to Build a Collapsed Oval Paper Bridge DIY Collapsed Oval Bridge Design is next to be built and tested… The kids determined that this type of bridge just wasn’t very stable. When a second penny was added to the bridge it totally collapsed. Once the strip is in place test the strength by adding one penny at a time. You will want just a couple of inches between the cups. Take a strip of construction paper 11 inches long and set it on two upside-down red cups. Step 1 Let’s test out a strip bridge first! It is the simplest of the kids bridge design ideas and sets the stage for how simple changes in design can make big impact when it comes to holding weight in the testing phase. The first DIY bridge you might create is a single strip bridge. Materials Needed to Build a Paper BridgeĤ Paper Bridge Design Directions #1 – How to Build a Single Strip Paper Bridge Our strip bridge didn’t turn out to be very strong… Let’s explore what forces and related bridge design is required to make a strong paper bridge and then test each of the bridges with a penny challenge. Building a strong paper bridge does not require as much concentration or attention to detail as you might think! In fact, with the right design, it can be quite simple. Let’s take a few minutes and look at three types of paper bridge design and how well each type of paper bridge holds pennies. Let’s see who can build the strongest paper bridge! Build a Paper Bridge This paper bridge building science activity is a great way to get your kids thinking about bridge building at home or in the classroom. Once they have built a paper bridge from common household items, they will test each paper bridge for strength to find out what is the best paper bridge design. Kids of all ages will have fun exploring this STEM activity of three different ways to build a bridge out of paper.
