- Post the data that you will use directly to the discussion area (such as a spreadsheet) or post a link(s) to the data.

- Briefly describe the mini-lesson you will use with your students. State the analysis tool and the analysis technique you will be using.

This mini-lesson uses Excel and the analysis technique of using formulas to simplify calculations. While learning about percent change in math class, students will import state-level census data into Excel. They will create a formula to calculate percent change, figuring out which states experienced the fastest and the slowest growth during the last ten years.

## Mapping the Earth

- Briefly describe the mini-lesson you will use with your students. State the analysis tool and the analysis technique you will be using.

This mini-lesson uses GIS and the analysis techniques of layering gis data and then turning layers on and off. While learning about mapping in Earth science class, students will use AEJEE GIS to interpret topographic maps. They will layer the topographic data together with orthophotos, hazardous waste sites, and transportation data to predict what areas might be affected by a natural disaster, such as flooding.
