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

• 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.
