Thinking Like a ScientistTransparency C


The Scientific Method 1. State the problem What are you wondering about?• Write the question(s) that the experiment

will try to answer 2. Collect information What do you already know? What can you find out?• Look for information about your question before you

begin your experiment• How have others looked at this question?

3. Form a hypothesis Based on what you know, what do you think will happen?• Predict what the result of your experiment will show.• Try to write your hypothesis as an “if/then’ statement

4. Test your hypothesis How will you conduct your experiment?• Describe the steps of your experiment• What materials will you need?

5. Observe and record your results What happened in your experiment?• Organize and record the data you collected.

6. Draw a conclusion Did you support your hypothesis? What new questions do you have?)• State whether you hypothesis was support• Share your conclusion with others

receive messages carried by the neurotransmitter

4Receptors

3Neurotransmitterscarry messages from one neuron across the synapse to another neuron.

Dopamine is the most common neurotransmitter in humans.

2 Synapsegap between neurons where messages travel across the synapse to another neuron

1 Axon Terminalsplaces where messages are changed from electrical to chemical and are released into the synapse

Transparency L Research Questions

How Science Is HelpingTransparency L

Research Questions

Study 1: Are neurotransmitters in the brain affected by cocaine addiction?

Study 2: How many 8th grade students in the U.S. have tried

alcohol at least once? Study 3: Are there differences between the brains of people who

take risks and people who do not take risks?

Study 4: Are children of alcoholics at greater risk for becoming alcoholics than children of non-alcoholic parents?

Study 5: Does drug dependence result from a problem in how the

brain’s neurons transmit messages? Study 6: Can using different rewards/consequences reduce

cigarette use? Study 7: Do specific neuron pathways reinforce the effects of

drugs? Study 8: Can studies of twins help us look for inherited risk

factors for substance abuse? Study 9: How do heroin users get the drug into their systems?

Transparency L (cont’d) – Research Questions

How Science Is HelpingTransparency L continued

Research Questions

Study 10: Do kids try marijuana just as often as they do cigarettes? Study 11: Are middle school students more likely to grow up to be smokers if one or both

of their parents smoke? Study 12: If a pregnant woman drinks alcohol, will her baby’s development be affected? Study 13: Is marijuana addictive? Study 14: Are middle and high school students who use smokeless tobacco more likely to

become cigarette smokers than students who don’t smoke at all?

Study 15: Can genetics play a role in substance abuse and its risk factors? Study 16: How many high school seniors become regular substance users? Study 17: Are adolescents influenced by other adolescents and adults who smoke? Study 18: Do regular marijuana users develop breathing problems?
