Learning objective:
students will be able to use both metric and imperial measuring tapes
Measuring the World Around Us
Measurement is the process of determining the amount of something. It helps us make sense of the world by comparing and organizing data. Learning to accurately measure length, area, weight, volume, and temperature can help us understand the world around us. Different units of measurement are used to help us communicate data, from millimeters to miles and Celsius to Fahrenheit.
measurement
Measurement: The process of determining the size, amount, or degree of something. Measurement is used to compare an unknown quantity to a known quantity.
Metric System: A system of measurement based on the meter, liter, and gram as units of length, capacity, and mass, respectively.
Instrument: Any tool or device used to measure a quantity or to carry out an experiment or survey.
Did you know?
The speed of light was first measured by French physicist Hippolyte Fizeau in 1849. The temperature of the sun's surface is measured to be around 5778 K. The foot was originally defined as the length of a human foot and was standardised as 1/3 of a yard in 1959.

Understanding Measurement
Measurement is the process of assigning numbers to physical quantities to describe them. We use different units of measurement to compare and understand quantities. Learning the basics of measurement is important for science and everyday life.
measurement
Measurement: The process of assigning a numerical value to a characteristic of an object or event.
Units of Measurement: A system of measurement that uses a specific set of units for measuring length, weight, capacity, time, and other physical characteristics.
Accuracy: The degree to which a measurement or calculation is correct or precise.
Did you know?
The ancient Egyptians used a cubit, which was the length of a man's arm from the elbow to the tip of the middle finger, to measure length. The British Imperial System of measurement was based on the length of a man's foot and was used until the late 1960s. The wavelength of light is the fundamental unit of length in the International System of Units (SI). It is equal to the distance travelled by light in a vacuum in 1/299 792 458 of a second.
