Climate and Earth's Energy Balance Lab

Positives

• This lab offers a series of in-depth lessons about Earth's energy budget and the greenhouse effect, including some hands-on investigations and assessments that aid student understanding.
• Videos animations and interactive media are provided as a way to help students master these difficult concepts.
  

Additional Prerequisites

• The concepts presented in this lab are fairly advanced and misconceptions can easily occur, especially for middle school students. Based on students' prior knowledge, consider first teaching students about the uneven distribution of heat from sunlight on a sphere before beginning Part A of this lab.
• In part C, the link for "What is the Greenhouse Effect?" is broken.
• Vocabulary terms include atmospheric composition, troposphere, stratosphere, solar radiation, and convection.
  
• It is suggested that teachers practice and set up the experiments ahead of time to anticipate any issues.
• Lab materials include clear plastic water bottles, digital thermometers, vinegar, baking soda, ice, pennies, shoe boxes, and clear containers.

Differentiation

• This lab is best suited to be taught in 3-4 class periods, where the total time required for all four parts is 150-200 minutes.
• Consider using any of the labs separately to provide a hands-on activity for students relating to weather systems, the atmosphere, the greenhouse effect, or energy balance.
• The experiments could be demonstrated for students if materials are in short supply.
  
• Related resources include this interactive simulation of the greenhouse effect, this lesson about radiation balance, and this video introduction about feedback loops.
