We suggest students work in pairs. This activity is designed to encourage students to collaborate and help each other by sharing ideas.

Prepare Paper

You can use scrap paper for this activity. Use a paper cutter to cut your 8-½ x 11” sheets in half, making sheets that measure 8-½ x 5-½”. You should have enough pieces of paper so that each student has six pieces. If you don’t have time for this preparation, you can use 8-½ x 11” sheets, but be warned: students can go through a lot of sheets. We use half sheets only to minimize how much paper you need.

Review Extension

We have provided an extension video that demonstrates our invention and experimentation process. This will give you some insights into the process and may be useful for your students as well.
