Scientific Method

What is the Scientific Method?

• experiments
• steps to solve a problem
• steps to create a theory
• steps to write and solve a law

In a experiment, how many variables should be tested during each experiment?

• It doesn't matter
• 1 variable
• 2 or more variables
• No variables

Why is it important for scientists to write/follow a procedure for an experiment?

• Others can repeat the experiment in the same way
• Mistakes made during the experiment are reduced
• It reviews any safety concerns for the experiment
• All of the above

Tell whether the observation statement is a qualitative or quantitative observation. "The object FEELS soft"

• Qualitative
• Quantitative

Tell whether the observation statement is a qualitative or quantitative observation. "The object is 4 inches long"

• suggestions to improve the experiment
• a summary of the results
• All of the options
• None of the options

A scientist notices that fish in a river near a factory are less active than those upstream. What is the first step the scientist should take in the scientific method?

• Form a hypothesis

• Make an observation

• Collect data

In an experiment testing the effect of fertilizer on plant growth, what would be considered the control group?

• Plants kept in darkness
• Plants given fertilizer
• Plants given no fertilizer

After conducting an experiment, what should a scientist do with the collected data?

• Analyze and interpret the data
• Start a new experiment
• Throw away/delete any unexpected findings

After observing plant growth, the student thinks, "If a plant is cloer to the window, then it will grow taller, because it is getting more sunlight". This is an example of a:

• Hypothesis
• Experiment
• Question
