Think like a sticky animal and build a graham cracker skyscraper, using only "bioglues" or glues that you can eat. Make your skyscraper as tall as possible, using the smallest number of graham crackers as possible.

2.build

collect

  • Graham crackers
  • Butter knife or icing tube for spreading glue
  • Edible glues from your kitchen (like peanut butter, jelly, etc.)

activity

  1. Break several graham crackers in half so you have squares.
  2. Using glue, place the graham crackers together, building up a skyscraper. You may need to put your skyscraper in the fridge for a few hours after building each story, to help your glues harden and set.
  3. Try to build your skyscraper as tall as you can (aim for at least 3 stories).

Glues are great for sticking things together. As humans we've invented many great glues (like Elmer's glue) that are usually made from artifical products (like petroleum). Animals and plants use glue for all sorts of things too, and they've made glue from natural substances (like mucus or slime).


Glues often need time to set or harden. Depending on the glues, there are several ways they may set. Some glues set by drying out, when all of their moisture evaporates in the air. Some glues set when they cool, like the glue from a hot glue gun. You may even need to put your skyscraper in the fridge occassionally to help it harden!
