Teach students about the observable properties of matter. Then, define and explain the property of flexibility. Afterward, students engage in the following activities:
First, students will practice predicting if various given materials are flexible or rigid. Next, they will prepare and then take part in an experiment where they will determine the flexibility of various materials. This experiment includes some data collected by the students during the experiment on a provided chart (on a slide and as a printable worksheet
). After the experiment, students can discuss their results and answer some given discussion questions. They will then use their results to sort the materials that they tested into the following categories: rigid, flexible but not elastic, and flexible and elastic. Then, they can participate in an activity where they spin a wheel for a material and then brainstorm ideas of what purpose or job that material might be useful for.
