Understanding the Scientific Method and Rain Experiment

What is the initial question posed about staying dry in the rain?

• How does temperature affect rain intensity?

• Does running or walking keep you drier in the rain?

• How does the type of clothing affect wetness?

• What is the best umbrella design?

What is the first step in the scientific method?

• Developing a theory

• Making observations

• Drawing conclusions

• Testing a hypothesis

What must a hypothesis be in order to be useful?

• Complex

• Theoretical

• Testable

• Proven

In an experiment, what is a variable that can change called?

• Constant

• Control

• Variable

• Factor

What is a controlled experiment?

• An experiment where all variables are changed

• An experiment with no variables

• An experiment where only one variable is changed at a time

• An experiment with multiple manipulated variables

What did the scientists conclude from their rainy day experiment?

• Walking keeps you drier than running

• Both walking and running keep you equally dry

• Running keeps you drier than walking

• Neither walking nor running affects dryness

What should a scientist do if the data does not support the hypothesis?

• Publish the results anyway

• Change the data to fit the hypothesis

• Revise the hypothesis or propose a new one

• Ignore the data

What is a scientific theory?

• A guess about how something works

• A well-tested explanation for observations

• A statement that summarizes a pattern in nature

• An untested idea

What is the difference between a scientific theory and a scientific law?

• A theory is a fact, a law is a hypothesis

• A theory is untested, a law is tested

• A theory explains, a law describes a pattern

• A theory is a guess, a law is proven

What does Newton's law of gravity describe?

• The attraction between two objects

• The speed of light

• The melting of ice

• The behavior of gases
