In this interactive, use results from a GCM to test how a spike in atmospheric CO2 levels could affect average global temperature, average sea ice cover, and atmospheric water vapor. This is part of Unit 1 of Interactives and Models: Carbon &... (View More)

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)

Unit two of the "Carbon Connections: The Carbon Cycle and the Science of Climate" curriculum examines the role of carbon and the carbon cycle in current climate. Students discover how carbon in Earth's system is monitored and also investigate the... (View More)

Unit one of the "Carbon Connections: The Carbon Cycle and the Science of Climate" curriculum introduces the role of carbon (as carbon dioxide) as an atmospheric indicator. Students examine the impact of geologic and climatic history on current... (View More)

This is a demonstration about the density of the planets. Learners will compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods. They will then dunk the "planets" in water to highlight the fact... (View More)

In this demonstration activity, students make structural models of gas molecules using pipe cleaners and polystyrene balls and test their molecules for their resonant frequency. Students shake the models, count vibrations, and compare the resonance... (View More)

In this textbook chapter, students review concepts of matter and energy as a precursor to understand how carbon dioxide traps heat in the atmosphere. This is the second chapter in the unit, Climate Change, which addresses the question of how human... (View More)

Students will learn about black holes through reading a NASA press release and viewing a NASA eClips™ video segment. Then students will use tables and mathematical expressions to compare black hole sizes and temperatures. Common Core State... (View More)

Leaners will grow a sugar crystal and learn how this relates to growing protein crystals in space. The lack of gravity allows scientists on the space station to grow big, almost perfect crystals, which are used to help design new medicines. This is... (View More)

In this activity, students are reminded that the Universe is made up of elements and that the heavier elements are created inside of a star. They are then introduced to the life cycle of a star and how a star's mass affects its process of fusion and... (View More)
