• problem

• control

• constant

• dependent variable

What is a correct hypothesis for:

IV: type of soda

DV: height of the fountain

• If the IV then the DV

• If the type of soda is grape the fountain height will decrease

• If the type of soda is grape then height of the fountain will increase

• If the height of the fountain is bigger then the type of soda was orange

What part of the experiment does this describe:

The same type of bean plant, the same amount of water, and the same soil were used.

• Constant

• Control

• Levels of IV

• Hypothesis

What is the correct formula to write a hypothesis?

• If the IV

  then the DV will (take a guess)

• If the IV is (pick a level of IV)

  then the DV will (take a guess)

• If the DV is (increase/decrease)

  then the Level of the IV

• The IV is (pick a level of IV)

  The DV will (take a guess)
