Presentation transcript:

1.I can develop a hypothesis from an observation. 2.I can manipulate an independent variable to show the effect on a dependent variable. 3.I can identify the controlled variable in an experiment.

not These hypotheses are not written correctly: French fries cause pimples. Studying for a test will help you earn a higher grade. 1) Fix them using “IF-THEN-BECAUSE.” 2) Underline the independent variable. 3) Put a box around the dependent variable.

French fries cause pimples. If a person eats french fries, then she will get pimples because the grease will clog her pores.

Studying for a test will help you earn a higher score. If a person studies for a test, then the person will earn a higher score because he/she will know more answers.
