Lesson 7: Building an Insulated Water Bottle

Overview

Students investigate the insulating properties of a variety of materials. Using their knowledge of heat transfers, students design an
insulated water bottle.  

Key Ideas

• Different materials conduct thermal energy at different rates. Metals conduct heat rapidly. Other materials, such as plastic and wood, do not conduct heat rapidly so can be used as insulators. 
• Knowledge of thermal conductivity differences is used to develop products and technologies that allow people to safely and efficiently use heat. 
• Depending on how they are used, materials can be used to slow or accelerate heat transfers. 

Lesson Goals

Students will:

• recognize that a thermal conductor is a material that allows heat to readily transfer through it. 
• recognize that heat is conducted at different rates through different materials. 
• use their knowledge of heat transfers to design an insulated water bottle.
