What do you get from making observations?

What types of observations are there?

Made by recording the properties or attributes of an object or event

Describes an object or event with your own words, impressions, feelings, senses

Typically cannot be measured with a number

Made by making a numerical measurement of an object or event

All measurements have a number and a unit

Usually based on the Systeme Internationale of Units (SI Unit)

Sometimes based on a scale system set by an international organization

Watch the following Bill Nye Science Video. Afterwards, write a personal response to answer the following:

Why is it important to make measurements? Describe a scenario where making exact

measurements is crucial. Describe a scenario where making a rough

measurement is acceptable. Which is your favourite unit of measurement,

why is it your favourite, and how is it used?

How would you measure the dimensions of the cabinet door, with no available equipment?

How would you instruct Mr. Chan to make more cabinet doors?
