This is a set of instructions for building a physical model. The model simulates the Sun's paths across the sky at summer solstice, winter solstice, and the spring and fall equinoxes. A bead simulates the Sun, moving along a cord, from rising along... (View More) the eastern horizon to setting on the western. The bead can be moved from path to path to demonstrate solar alignments, the solstices, and equinoxes. The model is created to be unique to the user's latitude, and is useful for including in lessons that teach about the seasons or archaeoastronomy. (View Less)
The importance of rainforests to Earth's biodiversity, climate and production of rainforest products is discussed in this textbook chapter. Includes an interview with an Amazonian rainforest scientist, a discussion of the competing perspectives of... (View More) different interest groups, and a summary of rainforest issues related to deforestation and logging. Students examine a time series of images of Rodonia, Brazil, and investigate the changes in land cover. There is an associated investigation, where students use image-processing tools to interpret a satellite image of the rainforest in Rodonia, Brazil. This is chapter 5 in the unit, A New World View, which introduces global systems science, emphasizing the concepts of environmental diversity, Earth as a system, and sustainability. The resource includes a textbook chapter, integrated hands-on and inquiry activities, links to current news articles, and a suite of pre- and post-unit assessments. A teacher's guide supports classroom use. The resource is part of Global Systems Science (GSS), an interdisciplinary course for high school students that emphasizes how scientists from a wide variety of fields work together to understand significant problems of global impact.

The lesson includes background information for the teacher, questions, and information about student preconceptions. This is lesson 4 of 4 from "The Cosmic Ray Telescope for the Effects of Radiation." (View Less)
In this lesson on cosmic rays, students will explain two examples of a cosmic ray detector. Includes information about student preconceptions and a demonstration that requires a geiger counter and optional access to a small radioactive source that... (View More) emits energetic helium nuclei (alpha particles), e.g., the mineral the mineral autunite, which contains uranium. This is activity two of four from The Cosmic Ray Telescope for the Effects of Radiation (CRaTER). (View Less)
In this lesson about cosmic rays, students will describe why cosmic rays are dangerous to astronauts. Includes information about student preconceptions. This is activity 3 of 4 from "The Cosmic Ray Telescope for the Effects of Radiation (CRaTER)."
In this lesson, students will learn how cosmic rays were discovered and what they are - including their size and speed. Includes background information for the teacher, questions, activities and information about student preconceptions. This is...
