Tootsie Roll Lab

Understanding the Scientific Method

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.

Materials Needed????

Tootsie Roll Student Science Notebook Pencil

Procedures

1. Get Tootsie Roll2. Remove wrapper3. Place candy in mouth4. Chew candy until finished making sure

to count each chew.

Don’t forget the Data!!!

Record the number of chews it took to completely finish the Tootsie Roll….

It took ________chews to finish my tootsie roll.

How can we represent this data?

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
