This investigation is based on the GISP2 H-core data collected in 1992 adjacent to the GISP2 Greenland summit drill site. Students examine the seasonal/annual nitrate record and use information from known volcanic eruptions to date the unique... (View More)
This textbook chapter describes how the Earth is unevenly heated by the Sun, and the role this plays in determining the Earth’s seasons, global winds, and weather events such as storms and tornados. The resource includes a demonstration model of... (View More)
This textbook chapter introduces the concepts of static and dynamic equilibrium, and discusses contemporary climate change. The greenhouse effect is presented in a discussion of Mars, Venus and Earth, the "Goldilocks" planet. Two investigations... (View More)
This textbook chapter presents ocean and wetland ecosystems, and describes how floating plastic trash endangers aquatic species. Oceanographer Jacques Cousteau is profiled. The resource includes a student action plan to reduce waste in their... (View More)
This textbook chapter summarizes the changes in the ecosystems found in the world's forests. This is chapter 2 in the unit, A New World View, which introduces global systems science, emphasizing the concepts of environmental diversity, Earth as a... (View More)
In this activity, students are introduced to light and colored gels (filters). Students make and test predictions about light and color using gels; learn about the importance of gels (filters) to astronomers; then analyze images taken with regular... (View More)
In this activity, students build a photocell detector, and use it to detect different colors of light in a spectrum. Then they place the detector just outside the red region of the visible light spectrum and see that the detector detects the... (View More)
In this activity, students learn that infrared light is reflected in the same manner as visible light. Students align a series of mirrors so that they can turn on a TV with a remote control when the remote is not in a direct line with the TV. As a... (View More)
In this activity, students learn that light carries information. Students also discover that infrared (IR) radiation is a form of light that in some cases behaves like visible light and in other cases behaves very differently. For example, some... (View More)
This is an activity about the Doppler effect. Learners begin by simulating the noise made by a passing siren. After learning that the change in pitch results from movement, they investigate the definition of frequency, calculate change in frequency,... (View More)
