Mrs. Anna Ward Qualitative versus Quantitative Observations

Come in QUIETLY and find your ASSIGNED seat quickly. On your desk, you will find a sheet describing the differences between Qualitative and Quantitative Observations. This Sheet will be attached into your science notebook, so take good care of it.

You should have your science notebooks today FRIDAY— Parent letters are due to your third block teacher You need to have reading material for SSR during the morning time before the school day begins You will have a quiz on classroom procedures

Review DO NOW!!! Sheets Set up Science Notebooks Short notes on Qualitative and Quantitative Observations Review Collaborative Work Procedures Lab on Sewer Fleas (OBSERVATIONS—Qualitative V. Quantitiative)

It is light green in color. QUALITATIVE (1)

It tastes sour. QUALITATIVE (1)

One leaf is 9 cm long. QUANTITATIVE (2)

It makes a loud pop sound. QUALITATIVE (1)

The mass of the computer is 1 ½ kg. QUANTITATIVE (2)

It smells sweet. QUALITATIVE (1)

The temperature of the room increases by 8 degrees C. QUANTITATIVE (2)

It gets darker over a period of time. QUALITATIVE (1)

The flowers cluster in 3 blooms. QUANTITATIVE (2)

Feels very rough. QUALITATIVE (1)

The Plant is short. QUALITATIVE (1)

Leaves are stiff. QUALITATIVE (1)

The veins are 3mm wide. QUANTITATIVE (2)

What are some qualitative examples? What are some quantitative examples? Which type of observation is more accurate and why?

I will lead you through setting up your interactive science notebook.

GOING FORWARD, I have a special technique to help you know what is important and what you should write down. Anything I need you to write down I will outline in RED.

Qualitative Observations are when you use your senses (sight, taste, smell, feeling and hearing) to note characteristics QUALITATIVE  QUALITY EXAMPLES: odor, color, state of matter

Quantitative Observations are characteristics than can be measured QUANTITATIVE  QUANTITY (or amount) Examples: density, mass, boiling point, melting point, length

You have been pre-assigned to groups based on your current seating. We are going to practice moving our desks in and out of groups.
