THE ISSUE OF THE DAY…

THINK OF A PROBLEM YOU SOLVED IN THE LAST WEEK AND DESCRIBE HOW YOU SOLVED IT.

SAVE FRED!• Challenge: What approaches do you use to

solve problems?

• Procedure: Read procedure on pages A-5 and A-6. Write one sentence that describes what you will be doing.

• Glossary: Hypothesis, Scientific Method (define)

SAVE FREDComplete the before column of

the anticipation guide #1 and 2 (tape into notebook).

Fred has been spending his summer boating on the great lakes. But he’s not too bright (after all, the brains of worms are pretty small.)  He’s never learned how to swim and he never wears his life preserver. The worst has happened! His boat has capsized and he’s stuck! Fortunately, his life preserver is in the boat, but unfortunately he does not know how to reach it without falling off and drowning.

SAVING FRED CONT.• Results: Use words and drawings to describe

exactly what you did to save Fred. Write your procedure as clearly and specifically as possible.

• Homework:• Analysis: Answer numbers 1, 4 & 5 on page A-6 - A-

7

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

PROBLEM SOLVING MODEL 1 1. Identify the problem.

2. Propose a solution.

3. Conduct an Experiment

PROBLEM SOLVING MODEL 2• 1. State the problem.

• 2. Propose a solution.

• 3. Conduct an experiment.

• 4. Analyze the data.

• 5. Make conclusions.

PROBLEM SOLVING MODEL 3 1. Conduct an experiment.

2. Discuss results.

3. Propose other solutions.

4. Conduct a different experiment.

TRADITIONAL SCIENTIFIC METHOD• 1. State the problem or question.

• 2. Propose an explanation (hypothesis).

• 3. Collect evidence (by conducting an experiment).

• 4. Analyze data.

• 5. Draw conclusions, revise and repeat experiment if necessary.
