2. Presented by: Erik Berg Eleni Koukoularis Jennifer Palmer Project: Precipitation

3. Why Weather? Unit Objectives:  Students will measure and record the frequency of precipitation and daily temperatures of their immediate area.  Students will use probe technology to measure the pH of their precipitation samples.  Students will input their data into an Excel program in order to calculate monthly precipitation totals for their area.Excel  Students will use their data from Excel to create a world-wide database using Access.Access.  Students will research precipitation, temperature and pH patterns around the world to formulate hypotheses about the effects of elevation, industry and proximity to bodies of water on weather patterns.

4. Elements of the Program:  Identification of the sampling area**  Collection date and time**  Air temperature**  Amount of precipitation  pH**

5. Where in the World…? As part of the data-gathering process, students will be required to document the latitude and altitude of their location.
