Introduction:  Students have an opportunity to practice skills needed in order to complete Real Time Data Project #1.

Objectives:

1. Students will be able to locate sites on a map using longitude & latitude.
2. Students will obtain real scientific data using today's technology.
3. Students will follow written directions.
4. Students will record scientific data in a useable concise manner.
5. Students will practice skills of unit conversion.
6. Students will familiarize themselves with Real Time Data available on the internet.

This is an exercise that allows students to gain experience using the Real Time Data internet sites necessary for Real Time Data Project #1.  Students should work in pairs or as a class led by the teacher.  Difficulties may occur in the introduction of various expressions of latitude and longitude.  It will be necessary that the students, by the time they are ready to start Real Time Data Project #1, be confidant in converting lat/long from (degrees:minutes:seconds) to (degrees with decimal).  In addition, students should understand the concept of Real Time Data and also understand the how to use the necessary internet sites.  As a result of this activity, students will learn the amount of ozone over there house.  This information will be used  in Real Time Data Project #1 as part of the graph interpretation skills.

Note:  This activity may be done in a one computer classroom since all students will be looking for the same location and will retrieve the same ozone amount.

Materials:

1. Internet Access
2. Calculator (optional)

1. Latitude & Longitude (An Interactive tutorial)
2. Longitude & Latitude (in degrees)
3. How Far Is It - PARC MapServer
4. Toms Database - Find the Ozone Over Your House

Procedure:

1. Review latitude, longitude and map reading skills.
2. Introduce the Internet Site "How Far Is It?" - be sure students understand the correct format to input their query data.
3. Student will record lat/long in degrees:minutes:seconds in their journal. Make sure students understand this notation.
4. Students will convert to degrees with a decimal

65:45:36 south latitude converts to
 -(65 degrees + 45 minutes * (1 degree/60 minutes) + 36 seconds * (1 minute/60 seconds) * (1 degree/60 minutes)) = -65.76 degrees latitude
5. Note North and East are POSITIVE and South and West are NEGATIVE
6. Use the Toms Database to calculate the amount of ozone over your house.

Follow-up:

1. Teacher should introduce upper ozone and lower ozone in simple terms of atmospheric position. (Troposhpere vs. Stratosphere)
2. Students should repeat this exercise until they are confidant in this application.
