Bird's Nests


your results

Sent in by:
Madison of OH

Be glad you don't have to build it with your beak!

Materials Needed

  • mud
  • straw
  • grass
  • twigs
  • string
  • sticks
  • eggs (you can also use hard-boiled eggs)
  • 3 rulers or yardsticks
  • tape



  1. Check with a grown-up before you begin.
  2. Using mud, straw, grass, twigs, sticks and string, try to build the strongest nest you can.
  3. Test out your nest by placing it in a low branch of a tree, or you can tape 3 rulers or yardsticks together into a triangle to simulate a tree branch. Place hard-boiled eggs in it. How many can it hold?

How can you make your nest even stronger? What other materials could you use to make your nest? Experiment and be sure to send us your results so we can share them with other ZOOMscientists.

At first, the nest fell apart on the ground. Then, we used glue to hold some parts together. We placed it in a tree and two new birds came!! It was so much fun.
