Important Measurements in Science • Distance • Time • Mass • Volume • Temperature
Distance • Measures the space between two locations. • Tools of measurement: rulers, metersticks, tape measure, lasers
Mass • The amount of matter that an object is made up of. • Tools of measurement: scale, triple beam balance
Time • Measures how long we have to wait between events. • Tools of measurement: clock, stopwatch, chronometer
