Activity Prep

Print Prep
In this lesson, students explore the different properties of materials used for clothing, such as texture, flexibility, and absorbency. In the activity, Mad Hatter, students use this information to design and build a hat that protects them from the Sun.

Prep Instructions

You will need access to water for this activity.

Each student will make their own hat, but groups of four students will share a cup of water for the Sweat-Soaker test.

Prepare Supplies

  • Cut a 3-foot length of string/yarn/ribbon for each student.
  • Tear off a 9” piece of aluminum foil for each student.
  • Fill each cup about halfway with water.
  • Optional: Provide a hand-held mirror so students can see their hats as they work on them.

Engineering Teacher Tip

We created the Hat Inspiration printouts for students who are stumped and frustrated by the task of making a hat. We suggest letting students try building on their own first, then providing these Inspiration Sheets only to those who may need additional help.
