Understanding the Scientific Method

2. 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
Pencils
Although this against the rules in my class. I have developed a question or problem statement based on this observation. What could it be?

3. My Problem Statement?
How many chews does it take to finish a Tootsie Roll? What could my hypothesis be?

4. 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.

5. Materials Needed????
Tootsie Roll
Student
Science Notebook
Pencil

6. Procedures Get Tootsie Roll Remove wrapper Place candy in mouth
Chew candy until finished making sure to count each chew.

7. 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?

8. 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 Roll
