First Step Make Observations to formulate a Problem statement

Ms. Crawford has observed that her science classes like to chew a variety of things during class.

Candy Gum PencilsAlthough this against the rules in my class. I

have developed a question or problem statement based on this observation. What could it be?

My Problem Statement?

How many chews does it take to finish a Tootsie Roll? What could my hypothesis be?

My Hypothesis………If Ms. Crawford’s students eat a tootsie

roll in science call then I think it will take them 50 chews to finish the tootsie

roll.

Lets Review the Scientific Method.

Problem Hypothesis Experiment

› Independent variable: The rate I chew the tootsie roll (fast/slow)

› Dependent: The number of chews to finish› Constant: Tootsie RollData Conclusion
