Overview
How many steps are in the Scientific Method?
What is the first and third step in the scientific method?
Question and hypothesis/research
What are three ways to communicate the conclusion to people?
You can communicate your results through a presentation, chart, or paper.
Question:
Does the temperature affect phone battery?
Scenario: A student wants to know if studying for longer periods of time will lead to higher test scores.
Question:
Does the amount of time spent studying affect test performance?
What are the 6 steps of the Scientific Method?
Question, Hypothesis, Research, Experiment, Analyze, and Conclusion
What is the hypothesis considered (hint: was in quotation marks on the hypothesis slide")
"Educated Guess"
What do you analyze during the analysis step of the Scientific Method?
Analyze your data points made during the experiment.
Scenario: A student wonders whether using their phone before bed impacts how well they sleep.
Hypothesis:
If a person uses their phone before they go to sleep/bed then their sleep quality will increase/decrease
A student enjoys listening to classical music when he studies and wonders if it helps his concentrate more.
Hypothesis:
If a student listens to classical music while studying then he will be able to /not able to concentrate more.
What do Scientist do scientist do with their scientific method experiments once they have completed them?
Publish or present the work.
What is the point of the Question step in the Scientific Method?
Identify what you want to find out.
What is important to lay out before starting your experiment?
Layout your variables (independent, dependent, and control)
Scenario: A student wonders whether wearing different types of shoes affects how fast you run.
Hypothesis:
Question:
Hypothesis: If a person wear a (certain shoe type) then they will run faster
Question: Does the type of shoe affect how you run?
Scenario: A student notices different cooking oils seem to make fried food crispier than others.
Hypothesis:
Question:
Hypothesis: If food is fried in (enter oil type) then it will be cooked crispier
Question: Does the type of cooking oil affect the crispiness of food?
What is the point of the Scientific Method?
Discover facts and principles that can be verified or tested. (multiple answers)
What is a hypothesis?
An explanation that is based on prior research/observations
What is the definition of an independent and dependent variable?
Independent: what is changing/ being manipulated
Dependent: What is being measured
A student notices they get sick often when they wash their hands frequently.
Hypothesis:
Independent variable:
Hypothesis: If a person washes their hand frequently then the number of germs will decrease/increase IV: methods of washing hands.
Scenario: A student feels that they do better in school when they get more sleep at night.
Hypothesis:
Dependent Variable:
Hypothesis: If I get more sleep at night then I will do better in school.
DV: Student's academic performance
Why is it important for scientist to publish/run experiments using the scientific method?
Educate others, collaborate, inform (other answers excepted)
What is important to do when you are coming up with a question for your research?
Be specific
What is the main graph that scientist use when trying to show their data?
Line graph, point graph (will accept bar graph)
Scenario: A student notices they react more quickly when they've had coffee in the morning?
Hypothesis:
Independent variable:
Dependent variable:
Control Variable:
Hypothesis: If the student drinks coffee then they will have a quick reaction time
IV: amount of caffeine
DV: reaction time of student
CV: type of coffee, time of day
Scenario: A student notices their heart rate increases when they exercise.
Hypothesis:
Independent variable:
Dependent variable:
Control Variable:
IV: intensity of workout
DV: Person's heart rate
CV: have various answers
