Focusing on the means used by the Incas to send messages over long distances, the lesson introduces students to the Inca Empire, which extended from northern Ecuador to central Chile and from the Andes to the west coast of South America between 1200 and 1535 CE.

In this project, you'll build a web mapping application that identifies which region of Samut Songkhram province should be the focus of conservation efforts. You'll retrieve one image for each decade since the 1970s from the Living Atlas Landsat archive for the entire study area. Once you have the images, you will alter the available multispectral data to enhance vegetation, land, and water. Then, you will configure the time animation tool in ArcGIS Online, and create a custom time-aware application for publishing your observations.

Students learn how energy consumption has changed over the past 100 years, why it has changed, and the impact it has had. Students brainstorm and categorize uses of energy, take part in an optional consumption simulation, interpret graphs about energy use, take surveys, and engage in small group and classroom discussions about energy comparisons.

The advantages and disadvantages of different kinds of non-renewable energy sources are the focus of this lesson. Students match different kinds of energy resources with their advantages and disadvantages, and then discuss whether these advantages and disadvantages are economic,ecological, or social. As an extension students identify the environmental impacts of their family’s electricity usage using EPA’s Power Profiler web site. The next lesson will deal with renewable resources.
