Scientific Method and Experimental Design Quiz

What is "the scientific method?" List the steps.

• A method to control variables in an experiment.

• A systematic approach to research involving observation, hypothesis, experimentation, and conclusion.

• A way to measure the dependent variable.

• A method to ensure safety in the lab.

What does it mean to have a controlled experiment?

• An experiment where all variables are changed.

• An experiment where only the dependent variable is changed.

• An experiment where all variables are kept constant except one.

• An experiment where no variables are controlled.

What is the independent variable?

• The variable that is measured.

• The variable that is kept constant.

• The variable that is changed or controlled in an experiment.

• The variable that is dependent on other variables.

What makes a "good" hypothesis?

• It is a random guess.

• It is a statement that can be tested and is based on observations and knowledge.

• It is a statement that cannot be tested.

• It is a statement that is always true.

Make a claim about the relationship between insect coloration and the percent of insects eaten.

• Brightly colored insects are eaten less by birds.

• Camouflaged insects are eaten more by birds.

• Brightly colored insects are eaten more by birds.

• There is no relationship between insect coloration and the percent of insects eaten.

What is the dependent variable in this investigation? How do you know?

• The insect coloration, because it is what is being measured.

• The percentage of insects eaten, because it is what is being measured.

• The type of birds, because it is what is being measured.

• The environment, because it is what is being measured.

Which of the following best describes a well-designed experiment in the context of the scientific method?

• An experiment that proves the scientist's hypothesis is correct

• An experiment that can be easily replicated by others

• An experiment that tests only one variable at a time

• An experiment that requires the use of advanced technology

Why is it crucial to analyze data in the context of the hypothesis and experimental design?

• To ensure the data fits the hypothesis perfectly

• To identify any correlations or patterns that support or refute the hypothesis

• To make the experiment easier to replicate

• To increase the quantity of data collected
