Activity 01
Pairs Practice: Tool Calibration Stations
Pairs visit three stations: calibrate compasses by sighting landmarks and noting magnetic variation, practice clinometers on school building heights with measured baselines, complete sample observation sheets for land features. Rotate stations every 10 minutes and discuss accuracy challenges.
Design a simple data collection plan for a local park.
Facilitation TipDuring Tool Calibration Stations, circulate with a metal object to demonstrate interference, prompting pairs to test and map deviations in three different school spots.
What to look forProvide students with a blank observation sheet template. Ask them to list three specific features they would look for and record in a school field, and the type of measurement (e.g., distance, angle, observation) they might use for each.
