Scientific Method Steps
What is the first step of the scientific method where you notice something happening or something that sparks a question?
What is observation?
In an experiment testing how sunlight affects plant growth, what would be the independent variable?
This variable is what you change or control in an experiment to test your hypothesis
Independent Variable
After making an observation, what is the next step where you ask a question that you want to find an answer to?
Problem/Question
If you were testing how different amounts of water affect the growth of plants, which would be the dependent variable?
What is plant growth (height, size, number of leaves)?
True or False: The dependent variable is what you change in an experiment to see its effect.
False
After conducting an experiment, you look at the data and analyze what happened. What is this step called?
Results
You want to see if plants grow better with blue light or red light. You change the color of the light for each group of plants. What is the independent variable?
What is the color of the light?
In an experiment where you test how different types of music affect concentration, what is the independent variable?
What is the type of music?
This step of the scientific method involves making an educated guess about what you think will happen in your experiment.
Hypothesis
In an experiment where you test if more sleep helps students score higher on tests, what would be the dependent variable?
What is the test score?
In an experiment testing how the amount of exercise affects heart rate, what would be the dependent variable?
What is the heart rate?
What are the six steps of scientific method?
Observation, problem/question, hypothesis, experiment, results, conclusion
In an experiment where you test the effect of different amounts of fertilizer on plant height, what would be the hypothesis?
What is "If I give plants more fertilizer, then they will grow taller"?
What are the acronyms that were taught to help remember the variables?
