Proper Lab Technique


Scientific Method

What is the first step in the scientific method?


Identifying the purpose, problem, or question


Scientific Method

What is the difference between qualitative and quantitative data?


Quantitative measures how much is there, qualitative measures what is there


Scientific Method

Identify this step: Gathering concepts, equations, and knowledge so you can integrate and apply them to the specific problem at hand.

Explain the Difference

Between variable and constant


Variable is a manipulated

measurement in a lab, while a constant remains unchanged



Between Independent and Dependent variables


Independent is manipulated by a

scientist and dependent is measured or observed



Theory and Law


Theory- how or why behaviors happen

Law- describes what happens



Clear and colorless


Clear-can see throughColorless- has no color



Accuracy and precision


Accuracy-result close to real answer

Precision-getting similar results each

trial


Proper Lab TechniqueIn a laboratory, the following should not be worn:a)Loose clothingb)Dangling jewelryc)Sandalsd)All the above


D- All the above


Proper Lab TechniqueIf you wear contact lenses in the school lab:a)Take them out before starting a labb)You do not have to wear protective gogglesc)Advise your instructor that you wear contact lensesd)Keep the info to yourself


C- Advise your instructor


Proper Lab TechniqueIf a fire erupts, immediatelya)Notify teacherb)Run for the extinguisherc)Throw water on the fired)Open windows


A-Notify Teacher



True or False: Lab work can be started upon entering the lab even if the instructor is not yet present.


False



ALL unauthorized experiments are prohibited.


True


Final JeopardyIf Jeffrey has 2 acorns and gives 1 to Sarah, how many acorns does Jeffrey have left? Use proper sig figs.
