  Lesson Plan: Redesigning a Car for the Environment Mark as Favorite (26 Favorites)

  Chemland’s city public transportation board has requested the class to help them determine the direction the city should move towards in reducing the carbon footprint. Students will be divided into groups and will come up with proposals of how to reduce the carbon footprint from carbon dioxide released from vehicles. The groups will represent different ways to reduce the carbon footprint via an alternative fuel source or a new technology. They will debate their findings to determine the direction that the city council should move towards to reduce the carbon footprint.

  Lesson Plan: Modeling Energy in Chemistry: Energy and the Electron Mark as Favorite (63 Favorites)

  This activity is designed for students to build a scientific argument about the relationship between energy and spectral lines by exploring how light interacts with atoms. In the process, students will examine proposed models of the hydrogen atom and use collected data to analyze the proposed models. They will then select one of the models and write a scientific argument to support their choice. Students will then review additional data to support and/or refute their selection. Based on their analysis, students will revise their selected model and construct a new argument to support their revisions.
