Reflection: Grappling with Complexity Thermal Expansion of Water - Section 4: Explain


In this lesson students used a simple model to visualize the effect warming ocean water has on sea level rise. An often overlooked consequence that media reports tend to not cover is thermal expansion, which contributes to about 25% of global sea level rise. 

I had to make a few adjustments to the initial water levels so that the lab results would deliver measurements that were consistent. I would make sure that you try this on your own before assigning to your students. 

Whatever sequence of lesson you choose to follow, this lesson ties in with lessons on albedo, heat transfer, greenhouse effect, etc.

Thermal Expansion of Water

Unit 3: Understanding Our Changing Climate: Systems Thinking & Global Warming
Lesson 10 of 10

Objective: SWBAT determine the relationship between heat and the expansion of water, represent graphically how water expands as it is heated, and connect this information to what is happening on a global scale.

Big Idea: Use this lesson to help your students model large global systems on a small scale.
