Every measurement has a measurement uncertainty. Discuss how precise and accurate measurement can be achieved in spite of the inherent measurement uncertainty. You could use either of the two options given below.
• Take a ruler and measure the height of the textbook three times. Record the three measurements, and discuss the uncertainty in your measurements. Remember to report the smallest markings on your ruler.

• Take an egg and a measure the weight of the egg three times. Record the three measurements, and discuss the uncertainty in your measurements. Remember to report the smallest markings or “resolution” on your scale.
