The Climate Change MEL
Below are links to resources that will help students use the Climate Change MEL and learn more about fundamental scientific principles related to climate and weather.
This article provides an provides an overview of the MEL diagram activities, using the Climate Change MEL as an example.Beyond the Controversy (Acrobat (PDF) 667kB Jun4 18)
Next Generation Science Standards Performance Expectations
HS-ESS3-5: Earth and Human Activity
- Analyze geoscience data and the results from global climate models to make an evidence-based forecast of the current rate of global or regional climate change and associated future impacts to Earth systems.
HS-ESS3-4: Earth and Human Activity
- Evaluate or refine a technological solution that reduces impacts of human activities on natural systems.
Model A: Climate change is caused by humans who are releasing gases into the atmosphere.
Model B: Climate change is caused by increasing amounts of energy released from the Sun.

Lines of Evidence
Evidence #1: Atmospheric greenhouse gas concentrations have been rising for the past 50 years. Human activities have led to greater releases of greenhouse gases. Temperatures have also been rising during these past 50 years.
Evidence #2: Solar activity has decreased since 1970. Lower activity means that Earth has received less of the Sun's energy. But, Earth's temperature has continued to rise.
Evidence #3: Satellites are measuring more of Earth's energy being absorbed by greenhouse gases.
Evidence #4: Increases and decreases in global temperatures closely matched increases and decreases in solar activity before the industrial revolution.

This Plausibility Ranking Task (PRT), which may be completed prior to using any MELs, helps students to understand the role of evidence in supporting or refuting models.

The Google Drive folder below contains MEL resource documents in the Google formats. In order to maximize the flexibility of our activities, the MEL Project Team wanted to make more resources compatible with virtual settings. We have made our MEL scaffolds available in Google formats, so that they can be copied, modified, and uploaded more easily on a variety of platforms and devices. Please note that to access all the materials for each MEL scaffold, you will need a Google account. View the README file first.
