Question

1. a doctor examines a patients sore throat and suggests that the patient has strep throat. she takes a sample to test for the bacteria that causes strep throat. what parts of the scientific method is she using? (3 pts)
2. you perform an experiment and find that the results dont agree with the hypothesis. what should you do? should you conclude that you made an error in your procedure? (2 pts)
3. a student is planning a science fair project called \does temperature affect how high a basketball can bounce?\

a. based on the project title, identify the independent and dependent variable. (4 pts)
b. name at least two factors that would be kept constant during the experiment.

1. what is the difference between law and theory? (2 pts)

extra credit - 3 pts write in the correct order:

1. drawing conclusion 2. making an observation 3. setting up experiment 4. communicating results
2. making claim/hypothesis 6. analyzing data 7. collecting data

Explanation:

4.

The doctor makes an observation (patient's sore throat), forms a hypothesis (patient has strep throat), and collects data (takes a sample).

You should not immediately conclude an error. Re - evaluate the hypothesis, check the experimental setup, repeat the experiment. Results that don't match a hypothesis can lead to new insights.

The independent variable is what is changed (temperature), and the dependent variable is what is measured (how high the basketball bounces).

Answer:

Making an observation, making a claim/hypothesis, collecting data
