This Jar is TOO Difficult to Open!!

In this lesson, students will review the basic ideas of heat, the direction it flows, and the results of this flow on the kinetic energy and expansion of the particles. Students will investigate this concept in a 5E lesson format using claim, evidence, reasoning in their conclusion. They will determine how different temperature water baths effects the ease/difficulty of opening jars with tight fitting lids and link these results to the knowledge that heat flows from warmer to cooler materials. Applying the knowledge that increasing the amount of heat of the matter will increase the kinetic energy of it's particles, will result in expansion of that matter. Because each type of matter has a different coefficient of expansion, the amount of expansion will vary in different materials. Students will realize that a jar with a tight fitting lid may loosen if hot water is applied.
