The document discusses different types of observations in the scientific method including qualitative observations which describe objects or events without measurements and quantitative observations which involve numerical measurements with units. It prompts the reader to think about the importance of making exact versus rough measurements in different scenarios and to choose a favorite unit of measurement. Finally, it presents a scenario where students must measure a cabinet door for replication without typical measurement tools and devise instructions for a shop teacher.

1. SNC1D0

2. Between what steps of the Scientific Method would you normally make observations? What is an observation? What do you get from making observations? What types of observations are there?

3. 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

4. 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

5. 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?

6. The Science Department wants to make more cabinets to store equipment. Sadly, all the rulers, meter sticks, string, and measuring tape have not arrived from delivery yet. 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? Work in groups of 2-3 and try to come up with a written solution!
