Online Simulation

Exploring the properties of materials with simulations doesn't substitute for hands-on experiments, but it can help reinforce & expand students' knowledge.

  • Tinkerball: Students experiment with different materials to get a bouncing ball to land in a cup.

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.

Preview activity
COVID-19 Adaptations
Students can work solo
Digital worksheets available
See our advice below

Students at home
Students can use the supplies below if they have them, or you can ask them to find other materials at home to construct their hat. Students also need the Mad Hatter's worksheet (printed or digital).
Students at school
If students are working solo, you'll need enough cups and spoons so that every student has one of each. The rest of the supply quantities should remain the same.
