Wanna buy a car?

• Identify 3 or 4 questions you need to know the answers to first. (groups, scrap paper)

• Form your hypothesis• Test your hypothesis• Reform another hypothesis, if the

first one does not work

CONTROL:

• no change- • use to compare • (ex. No fertilizer, normal sunlight,

etc.)

INDEPENDENT VARIABLE

• : factor that was changed• ex. Using fertilizer, adding more or

less light• - can only have 1 variable at a

time

DEPENDENT VARIABLE

• : the factor you measure• growth, time• It depends on what you

measure

CONSTANT

• factors that are the same between the control and independent variable

Hypothesis: Plants grow taller with

fertilizer • Control

• Independent variable

• Dependant variable is

Constants will be

Now,

•Work in groups to answer the questions for the 3 scenarios. If you do not finish, it is homework.
