Flexibility

Flexibility

TEKS Objective

Classify matter by physical properties, including shape, relative mass, relative temperature, texture, flexibility, and whether material is a solid or liquid. 

Essential Understanding

The student knows that matter has physical properties and those properties determine how it is described, classified, changed, and used.

Science Background

Flexibility and Stiffness: Wikipedia (website) - A technical description of flexibility and stiffness in terms of the property of an object.

Signature Lesson

 

To Squash or Not to Squash: Pearson Publishing (PDF) - In lesson 18, students investigate, test and classify different objects based on their level of flexibility (can an item be squashed, bent, twisted or stretched?). The PDF includes additional lessons that are unrelated to this activity.

Supporting Lessons

Sneaking Up on Sneakers: TeachEngineering (website) - Each sport has different footwear requirements. Students will participate in a variety of sports, observing and discussing the different motions and requirements of each, and use the information to design their own line of shoes.

Elaboration Lessons and Extensions

Ball Bounce Experiment: TeachEngineering (website) - Could you play tennis with a baseball or soccer with a basketball? This activity compares different kinds of balls in terms of weight, strength, hardness, and flexibility.

Assessment Ideas

Provide groups of students with three different objects made of different materials (such as a wooden ruler or pencil, notecard and plastic drinking straw). Have them rank the objects least to most flexible, and make a list of the reasons for the rankings they created.
