Weather Watchers - Measuring Weather
Students explain ways that meteorologists measure and predict weather, collaborate on creating some weather measurement instruments and keep a weather journal for one week.
Curated OER
Measurement Via Triangulation
Students investigate various common terms of measurement, sort them into categories, select the uncommon terms, and construct conversion tables for both the common and the uncommon terms of measurement.
Curated OER
Magnitude of the Richter Scale
Learners examine how a Richter scale operates. They create a booklet illustrating each rating on the scale. They discover how engineers use different measurement tools.
