Data collection practice.
Students will use a GPS device to gather geo-referenced storm sewer
data.
1. Instruct students they will be practicing data collection of
storm sewers today.
Give each student a copy of the handout: Data Collection Sheet Questions.
2. Instruct students to complete the questions on the Data Collection Sheet Questions handout.
3. Review and discuss answers with students.
4. Hold a class discussion on group roles for data collection.
Emphasize accuracy and validation, writing neatly, and having partners validate
the data written on the data collection sheet.
5. When walking to field site area, review cardinal directions
with students.
Have students notice the magnitude in latitude and longitude coordinate position
changes as they walk.
6. Locate storm sewers near the school and have students complete
data collection sheets.
Emphasize accuracy and validation, and writing neatly.
At intersections, have students point out on the paper map where they are currently
standing.
In the field:
• Verify students’ data collection as soon as points are taken and
provide immediate feedback.
• Review any inaccuracies in data collection on site points.
• Point out any questionable numbers written with low quality handwriting.
• Make sure accuracy is recorded.
• At intersections, ensure that the correct storm sewer location check
box has been marked.
• Ask students at intersections:
1. Are we on the north side or south side of the street?
2. Are we on the east side or west side of the street?
Materials needed:
GPS units
Clipboards
Data collection sheets
Paper map of area
Tape measures
