Observation vs. Analysis Slime Lab Observation vs. Analysis

Warm - Up For the following, give the location and briefly explain how it is used. Fire extinguisher Aprons Safety shower Broken glass disposal Fire Blanket Eye wash First Aid kit

Objective Today I will be able to: Discuss the importance of safety in a chemistry lab. Differentiate between qualitative and quantitative observations by completing the slime lab.

Homework Study for Lab Equipment/ Safety Quiz Tomorrow!!! Finish Lab

Agenda Warm – Up Review Safety Slime Lab Exit Ticket

Discussion What is an observation? What is the difference between a qualitative and quantitative observation?

Slime Lab Safety Wear goggles, aprons and closed toe shoes Do not eat the slime It is okay to touch it since borax is an ingredient in laundry detergent

Post Lab Questions Which of the tests that you performed were qualitative? How do you know? Which of the tests were quantitative? How do you know? Write at least two reasons why you think this lab investigation was chosen to be the first for the year. Why do you think each reason is important?

Exit Ticket Give an example of a qualitative and quantitative observation.
