If it falls over, she should go back to the drawing board and try again. When your child is all done building, test the tower for strength by trying to blow it over.Roll more paper sticks as necessary to make your tower taller.Use the stack of paper sticks and the roll of masking tape to make the tallest free-standing tower possible.Roll up 15 more pieces of paper in the same way.When it's all rolled up, use a piece of masking tape to secure the end.Roll up one piece of paper from one corner, like this: Pin.A stack of 8.5"x11" paper - We used plain white typing paper, but you could also use construction paper or any similarly sized papers.(We keep a box for scrap paper - papers where one side has been printed on, usually for contracts, misprints, calendars, and the like.) Paper Tower Materials Grab a big stack of scrap paper and get started. Grace did it once a few months ago at the Girls in STEM workshop at a local science center, and she loved it. This is a very simple engineering activity that uses trash to make a cool project. Christmas Crafts for Toddlers & Preschoolers.You can use this video to review the steps of the engineering design process with your students. It is unlikely that your students' towers will work perfectly on the first try-they might even collapse! Your students might need to iterate by testing and tweaking their designs multiple times so they can continually improve them. You can also use this project to demonstrate the engineering design process. An I-beam (where the cross section looks like a capital letter I) is a common shape used in many structures. The cross section of a piece of paper rolled into a tube is a circle. This rectangle bends very easily in the thin direction. For example, the cross section of a flat piece of paper is a (very thin) rectangle. This resistance to bending is determined by the beam's cross section. It becomes much harder to bend the paper if you fold it in half multiple times or roll it into a tube. For example, it is very easy to bend a flat piece of paper. The shape of a beam can dramatically affect its strength.They are anchored to the ground and prevent the tall, skinny towers from falling over. For example, the long cables connected to the top of the radio towers in Figure 2 are called guy wires. These parts can only be in tension (think about what happens if you try to "push" a rope), but they can still be useful. Sometimes towers include ropes, cables, or chains as part of the design.Beams can be in either tension or compression, depending on how a tower is designed. An object that is being "squished" is in compression and an object that is being pulled on is in tension. Can your students identify any trusses in Figures 1 and 2? Multiple beams can be combined to make trusses.
