In this paper and pencil exercise, students create graphs that describe the effect of a series of experiments using Daisy World, an energy balance model, that can be used to demonstrate concepts of equilibrium, homeostatis, and positive and negative feedbacks. Internet access and exploration with the actual Daisy World model is ideal, but not required. The resource is Activity 6 of the learning module, Global Balance, part of the lesson series Potential Impacts of Climate Variability and Change.

The purpose of this activity is to identify global patterns and connections in environmental data contained in the GLOBE Earth Systems Poster, to connect observations made within the Earth Systems Poster to data and information at the National Snow and Ice Data Center, and to understand the connections between solar energy and changes at the poles, including feedback related to albedo.

This article, written for students in grades 4-5, introduces the concept of albedo and describes the shrinking of Arctic sea ice. Modified versions are available for students in younger grades.

This NASA video discusses the impacts of the sun's energy, Earth's reflectance, and greenhouse gases on the Earth System.

In this activity, students analyze the results of an experiment, conduct research, and describe the potential importance of positive and negative feedbacks in governing the response of the Earth system. Teacher background information, assessment suggestions, and a scoring rubric are included.This is Activity 5 of the learning module, Global Balance, part of the lesson series, The Potential Consequences of Climate Variability and Change. Completing A Sense of Balance: Activity 1 in this module is a prerequisite to complete this investigation.

Students explore how mathematical descriptions of the physical environment can be fine-tuned through testing using data. In this activity, student teams obtain satellite data measuring the Earth's albedo, and then input this data into a spreadsheet-based radiation balance model, GEEBITT. They validate their results against published the published albedo value of the Earth, and conduct similar comparisons Mercury, Venus and Mars. The resource includes an Excel spreadsheet tutorial, an investigation, student data sheets and a teacher's guide. Students apply their understanding to the real life problem of urban heat islands and deforestation. The activity links builds on student outcomes from activities A and B: "Finding a Mathematical Description of a Physical Relationship," and "Making a Simple Mathematical Model." This is Activity C in module 3, Using Mathematical Models to Investigate Planetary Habitability, of the resource, Earth Climate Course: What Determines a Planet's Climate? The course aims to help students to develop an understanding of our environment as a system of human and natural processes that result in changes that occur over various space and time scales.

In this activity students download satellite images displaying land surface temperature, snow cover, and reflected short wave radiation data from the NASA Earth Observation (NEO) Web site. They then explore and animate these images using the free tool ImageJ and utilize the Web-based analysis tools built into NEO to observe, graph, and analyze the relationships among these three variables.

In this lesson, students explore reasons why temperatures in particular Colorado cities are rising.

In this resource, students watch a 2-minute video explaining albedo. The video shows visualizations of albedo across Earth and how it can change. Students will interpret the images in the video and answer questions about albedo.

This video provides a good overview of ice-albedo feedback. Albedo-Climate feedback is a positive feedback that builds student understanding of climate change.

This lesson has students investigate how albedo is contributing to temperature increasing in some places, like cities, are increasing at faster rates than elsewhere.

This lesson has students explore what land use changes are happening and how changes in surface color affects temperatures in cities.
