Observations, measurements, or data collected through established and recognized scientific processes. Multiple Choice A.Evidence B.Hypotheses C.Theories D.Consequences
Controlled experiments typically involve testing two or more variables at a time. True or False False Controlled experiments involve testing only one variable at a time.
In the leaf toughness experiment, the leaf’s exposure to sunlight was the ____________ variable and how easily the leaf ripped was the ___________ variable. Fill in the Blank manipulated responding
