In this lesson students investigate the effects of black carbon on arctic warming and are introduced to a mechanism of arctic warming that is not directly dependent on greenhouse gases in the atmosphere: black carbon deposition on Arctic snow and... (View More) ice. It can also be used to introduce the concept of albedo. Prerequisite knowledge: students understand the concepts of absorption and reflection of light energy. This lesson is designed to be used with either an Earth/environmental science or chemistry curriculum. It may also be used as an enrichment activity in physics or physical science during a unit on energy. Includes suggested modifications for students with special needs and low technology option. Requires advance preparation, including freezing ice samples overnight. (View Less)
This activity allows participants to build a paper model of the GPM Core Observatory and learn about the technology the satellite uses to measure precipitation from space. Directions explain how to cut, fold and glue the individual pieces together... (View More) to make the model. The accompanying information sheet has details about the systems in the satellite including the Dual-frequency Precipitation Radar (DPR), the GPM Microwave Imager (GMI), the High Gain Antenna, avionics and star trackers, propulsion system and solar array, as well as a math connection and additional engineering challenges.

In this interactive, manipulate the future sources and sinks of carbon to estimate the atmospheric CO2 levels and global temperatures in the future. This is part of Unit 3 of Interactives and Models: Carbon in the Future & You.
Using global data sets with monthly resolution, you will adjust variables in this empirical climate model to test the degree to which natural and human influences can account for observed global temperatures from 1979-2010. This is part of Unit 3 of... (View More) Interactives and Models: Carbon in the Future & You. (View Less)
This interactive model lets you manipulate and work to balance the biologic (e.g., photosynthesis, respiration) and human processes that replicate the observed CO2 record from Mauna Loa. This is part of Unit 2 of Interactives and Models: Carbon Now.
Scientists use various types of records to understand the rates of change in Earth's past climates, and the climate connections in the Earth system. Use this interactive to compare climate data from around Earth, and investigate whether they... (View More) indicate the same patterns of past climate change. This is part of Unit 1 of Interactives and Models: Carbon & Climate in the Past. (View Less)
Unit three of the "Carbon Connections: The Carbon Cycle and the Science of Climate" curriculum examines the role of carbon and the carbon cycle in future climate. Students discover how scientists determine Earth's average temperature and the role of... (View More) climate models in understanding the size of some forcings on temperature. Students are challenged to reduce their electrical energy usage and to critically evaluate claims about carbon and climate. The unit contains five lessons entitled: Your Temperature Connections, Testing Forcings, Future Forcings, It Starts at Home, and Climate Claims. Each of the five lessons includes focus questions, hands-on activities, virtual field trips, and interactive models. (View Less)
