Pulverizes the crap out of them and you create a great material to use for building a protective shell. If your kid ever has to do that one, we had great success by mixing Elmer's glue and toothpicks in an old blender (to be thrown away, obviously). Once you have a basic structure, you can begin to add more marshmallows and toothpicks. The marshmallows should be placed at the ends of the toothpicks, with one marshmallow in the middle. Thankfully, we won that battle!! I can't stand it when the kids are given an important project, but no parameters on which to follow to actually DO it. To build a strong marshmallow bridge, start by building a basic structure using two marshmallows and three toothpicks. With no rubric handed out, we fought that one with both teacher and principal. Well, he ended up getting downgraded because he used the "wrong" type of glue according to her. DS built a great bridge all by himself (DH hovered, though ). I would INSIST on one if the bridge is going to be worth more than a minimal grade.ĭS did this in middle school and the extremely DISORGANIZED teacher told them "just go build a bridge out of toothpicks and glue" and that was it. Whatever you do, make sure that the teacher sends home the rubric on how the bridge should be built, required materials, things that are "no-no"s. The bridge-and the dropping an egg 3 stories without a parachute were my 2 most favorite science projects ever. Recreate a real-life building dilemma in your classroom A company of five to six students has a mission: to build a bridge. I would encourage her to research different designs of bridges, what types of different structures their are and which she think she might be able to best replicated. Start with uniform building blocks I decided to make easier building blocks by first gluing toothpick head to toe, as it were, and by putting the fat end and the skinny end together, we get a uniform width, flat, and stronger, building block. It didn't look like a functional bridge or anything-just something that could have weight supported from it. The Toothpick Bridge-Construction Construction technique is of great importance to success. So I did 3 or 4 layers of sticks glued together.they were angled at 90 degrees roughly (maybe less, I didn't measure) and on one layer they went in one direction and on the next layer it was the opposite direction and then alternated for the number of layers. Mine was done for Physics-but I just thought simple geometry and remembered something about triangles being a better support system than squares. My question for you is what weight are they supposed to support and are there any other restraints on dimension? I did a criss cross design and it held 250 pounds. I made mine with popsicle sticks (we had much more leeway in materials for our class that the prof did later limit for future classes).
