(2.2C) Collect Data
The student is expected to collect data from observations using simple equipment such as hand lenses, primary balances, thermometers, and non-standard measurement tools.
By observing common objects through a hand lens, students develop important observational skills and also learn about magnification.
Balances are used to measure or compare the weight or mass of different objects. The activities in this section help student learn to use a balance.
What is the difference between temperature and thermometer? Here, students learn how to use a thermometer to measure temperature changes in a variety of ways.
Any standard-sized object can be used as a relative measurement tool. In this Signature Lesson, students use candy bar and toothpick measures to build their understandings about units and measurement.
