Formulating An Hypothesis If ……IV……… then, ……DV…

Write down the IV (independent variable) and the DV (dependent variable). Then write a hypothesis in an If…… then format.

Hypothesis- Review A hypothesis is an _____________. Educated guess

Independent Variable - Review The independent variable is the variable that is manipulated or C________ on purposed. hanged

Dependent Variable- Review The dependent variable is the r________ variable. The dependent variable can be m________. esponding easured

Scenario: Chocolate may cause a sick stomach. IV : ___________________________ DV: __________________________ CHOCOLATE SICK STOMACH TESTABLE HYPOTHESIS: IF I eat 20 pieces of chocolate THEN it will cause my stomach to feel sick!

Scenario:Salt in soil may affect plant growth. IV : ___________________________ DV: __________________________ SALT IN SOIL PLANT GROWTH TESTABLE HYPOTHESIS: IF I mix 20 grams of salt in soil, THEN my plant will grow two centimeters higher than normal.

Scenario: Teens may grow more if they drink lots of milk. IV : ___________________________ DV: __________________________ Lots of milk Teens may grow more TESTABLE HYPOTHESIS: IF my 16 year old sister drinks milk everyday for 2 years THEN she will grow 2 more inches!

Activity Time!!! Show me what you have learned! Let’s formulate some hypotheses!
