Solving Problems Discussion Questions

How Do you solve problems?

Do your ways of solving problems depend on the kind of problem you have to solve?

How do scientists solve problems? What kind ofproblems do scientists work to solve?

Answer in White Space

Have you learned about any of the methods scientists use to solve problems?

How do scientists know what to do?

Are these methods similar to the ones you use to solve problems?

Problem-Solving Model 1

1. Identify the problem.2. Propose a solution.3. Conduct an experiment.

4

Problem-Solving Model 2

1. State the problem.2. Propose a solution.3. Conduct an experiment.4. Analyze data.5. Make conclusions.

4

Problem-Solving Model 3

1. Conduct an experiment.2. Discuss results.3. Propose other solutions.4. Conduct a different experiment.

4

Traditional Scientific Method

1. State the problem or question.2. Propose an explanation, also known as the hypothesis.3. Collect evidence. (Conduct an experiment.)4. Analyze data.5. Draw conclusions and, if necessary, revise and repeat the experiment.

HypothesisYou walk past a school in the morning. As you stroll by, you hear a bell ring. A minute later, you pass a child running in the direction of the school. What is your hypothesis about why the child is running?• The child is late for schoolWhat other explanations, or hypotheses, could you make about why the child is running?• She is running for exercise• She is late for a school bus. • A dog is chasing her• The child is late for school

Hypothesis

A sign identifies the school as Franklin High School, and the child appears to be no more than nine years old. Would you change your hypothesis? Why or why not?

Analysis Questions

You can solve problems in many different ways. In fact, you may use more than one way to solve a single problem.

1a. Which of these ways did you and your partner use to save Fred?1b. Choose three of these ways, and record a problem that could be

solved using each method.

2. As a class, discuss the ways in which various groups of partners saved Fred.

How were your problem-solving methods similar?How were they different?

Analysis Questions

3. Do you think scientists only follow one method to solve problems? Explain.

4. The traditional scientific method includes the following steps for solving problems: Step 1. State the problem or question. Step 2. Propose an explanation, also known as the hypothesis. Step 3. Collect evidence. (Conduct an experiment.) Step 4. Analyze data. Step 5. Draw conclusions, and, if necessary, revise and repeat the experiment.

When you saved Fred, did you follow all of these steps in this order? Explain.

Reflection

7. Reflection: People face problems in their lives every day. What did you learn from this activity that you can use to solve other problems? How do you think this is different from how scientists solve problems?
