Measurements for a Rainy Day

In this Activity, students collect data outdoors on a rainy day using plates and paper towels and use the information to calculate the rate of rainfall. This Activity reinforces ideas about density, mass, volume, area, length, and units. The terms precision and accuracy could be introduced and discussed, as well as the problem of selecting appropriate samples for measurements that are representative of a large quantity of material or a complex phenomenon. The use of significant digits in measurements and calculations can be emphasized. Students also practice the skills of making observations and taking careful, quantitative measurements.
