In this introductory textbook chapter, energy is defined and its sources, forms, and flow are introduced. Students are introduced to the first law of thermodynamics, conservation of energy. The resource includes links to current news articles, and a... (View More) suite of pre and post unit assessments. A teacher's guide supports classroom use. This is the first chapter in the unit, Energy Flow, exploring the flow of energy through the atmosphere, oceans, land, and living things over short and long timescales. The resource is part of Global System 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.

This online, facilitated course is designed for middle-school educators wishing to teach global climate change. The course uses a problem-solving approach and interdisciplinary STEM methodology to engage middle-school students and help them... (View More) understand the causes and effects of climate change, the differences between climate and weather, and how actions and nature affect the environment. Educators access the course by enrolling and paying a course fee; the course syllabus is available online. (View Less)

In this textbook chapter, scientists studying the concentration of becomes CO² in the atmosphere are profiled. The techniques for measuring and recording carbon dioxide concentrations at the Mauna Loa Observatory are described. A link to a video... (View More) clip of an interview with NOAA scientist Dr. Pieter Tans is included. This is the fifth chapter in the unit, Climate Change, which addresses the question of how human activities are changing Earth's climate. The resource includes three classroom investigations, 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.

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) frequencies of different gases. Students learn that photons of infrared energy vibrate at the right frequency to transfer their energy to carbon dioxide and methane, which in turn causes those molecules to vibrate, which is experienced in the real world as heat. The teacher's guide includes illustrative videos for this resource. This activity is supported by a textbook chapter, What's So Special about CO²?, part of the unit, Climate Change, in 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.

Students will use NASA's Global Climate Change website to research five of the key indicators (vital signs) of Earth’s climate health. These indicators are: global surface temperature, carbon dioxide concentrations, sea level, Arctic sea ice, and... (View More) land ice. They will use this information, shared in their expert groups, to create an informative poster about their assigned key indicator. The poster will be used by other groups to learn about all five of the key indicators and how Earth scientists use these indicators to analyze changes in Earth’s climate. The lesson plan uses the 5E instructional sequence. (View Less)

Working in pairs, students will create experimental conditions in terrariums in order to study what plants need to live. Variables to study include the presence or absence of soil, water, and sunlight. Students will record the growth of radish... (View More) plants as well as observations of "the water cycle" in their terrariums. At the conclusion of their experiments, students will share their results with the class and discuss how water, Earth materials, and air are all necessary to support living things. The activities use commonly-available or inexpensive materials (e.g., chart paper, clear soda bottles, potting soil, radish seeds, paper towels, water, tape, foil, and index cards). This is the first of three sets of learning activities that are companion activities to the Elementary GLOBE children's book, All About Earth: Our World on Stage. Includes a teacher implementation guide. GLOBE (Global Learning and Observation to Benefit the Environment) is a worldwide, hands-on, K-12 school-based science education program. (View Less)
