Develop a hypothesis (“If, then” statement) Design an experiment & make observations Analyze the data Draw conclusions Reflect, modify and repeat

Variable: a factor or condition that can change in an experiment. EX. What variables might affect the taste a homemade pizza?

 On a piece of scrap, write your name and list the 5 steps to the scientific method.

   Tests a hypothesis in a careful way All variables are held constant (same) except for the manipulated ◦ Most have a control which is a group that does not get the treatment ex. If you’re testing the effect of fertilizer on plant growth, the control will not get any fertilizer.

 Manipulated (Independent): the variable that is intentionally changed in an experiment  Responding (Dependent): the variable that might be affected by changing the manipulated variable  Controlled: the variable that is not changed

 ◦ ◦ ◦ A student wanted to see if adding different amounts of cola to radish seedlings would affect how tall they grew. In this experiment, what is the manipulated variable?

What is the responding variable?

What should stay the same (controlled variables)?

Observation Using your senses to gain information about the world around you

Hypothesis An educated guess, possible answer to a scientific question that can be tested

Theory A basic hypothesis supported by many experiments over time
