This is a Tug of War activity to spur the conversation about the controversy of the potential danger of cell phone usage. Prior to this, the students would have learned about the structure and energy of electromagnetic radiation.
This lesson covers different aspects of the major greenhouse gases - water vapor, carbon dioxide, methane, nitrous oxides and CFCs - including some of the ways in which human activities are affecting the atmospheric concentrations of these key greenhouse gases. This is lesson six in a nine-lesson module about climate change.
This lesson explores the chemistry of some of the greenhouse gases that affect Earth's climate. Third in a series of 9 lessons from an online module entitled 'Visualizing and Understanding the Science of Climate Change'.
In this unit students investigate the cause of sunburns, the function of sunscreen, and the ways in which chemists determine the molecular structure of matter by applying relationships about how light interacts with matter on an atomic or molecular level.
THE PATTERNS APPROACH
The Patterns Approach to science instruction emphasizes the use of mathematical and phenomenological patterns to predict the future and understand the past. Students construct science knowledge by making an initial “wild-guess”, asking questions, planning and conducting experiments, collecting data, finding a mathematical model that fits their data, explaining the phenomenon based on that model, then finally making a data-informed prediction. Harnessing their own experiences, students compare and contrast low-evidence predictions (wild guesses) to their data-informed prediction to live the experience and learn the value of evidence-based reasoning. Additionally, students engage in several engineering projects in each course, where they must use the Patterns they discover in their designs to optimize their solutions. The Patterns Approach utilizes technology, student-constructed knowledge, frequent opportunities for student talk, and language supports to ensure the engagement and success of every student. By emphasizing, rather than removing, the mathematical connections to science, the Patterns Approach supports student conceptual understanding by connecting real-world inquiry experiences, graphical representations, and mathematical representations of science phenomena.
