DISCUSS:

Every spring, birds build nests. Why does a bird need a nest?

Can you think of ways having a nest helps a bird?

Some birds use twigs to make a nest that’s shaped like a bowl.
You don’t have twigs, but you do have a paper bag. Discuss:

the sides of the bag.

Your bag started out flat. Suppose a bird laid an egg on that flat bag.
Watch what would happen. Now watch what would happen if a bird
laid an egg in the nest you made from a bag. Discuss:

Activity Prep

Print Prep

In this lesson, students learn why spring is the best time for babies to be born. In the activity, Build A Bird Nest, students make a model of a bird nest and notice how birds can change their environment to meet their needs when they build their nests.

Preview activity
Number of students:

I have a Mystery Pack

Blank Paper (8.5 x 11")
30 sheets
Crayons
Colored pencils will also work.
Details
90 crayons
Scissors
30 pairs
Soft Materials
Students will use these to pad their nest. You can use tissue paper, facial tissues, paper towels, toilet paper, cotton balls, or even scraps of fabric or yarn.
Details
90 items
Paper Lunch Bags
30 bags
Prep Instructions

We suggest students work in pairs. Homeschool students can work on their own.

Get Creative With Materials Distribution (Optional)

Students will be lining their paper bird nests with tissue paper and/or other soft material. If you have a high tolerance for chaos, you can put these materials at different stations around the room — and have your students “fly” to the stations to gather their materials. It’s fun, but chaotic.

We also suggest encouraging students to modify the materials you provide -- tearing and crumpling them to make them fit in their nest. That’s what birds do, after all!

Surprise students with a pompom egg! (Optional)

If you have a supply of pompoms, consider surprising each student with a pompom “egg” for their nest! We think 1-inch pompoms are about the right size for a paper bag nest.
