This is an educated guess, or what you think is going to happen.
Hypothesis
An experimenter wants to find out if wearing a seat belt affect the passenger motion when a car stops suddenly.
What is the independent variable in their experiment?
Wearing or not wearing a seat belt.
What is the first step of the Scientific Method
Make an observation
This is the variable that is being measured.
Dependent Variable
An experimenter wants to find out if wearing a seat belt affect the passenger motion when a car stops suddenly.
What is something they should research before conducting their experiment?
Many different answers!
How does a seat belt stop motion, force and motion, what makes things move when motion is stopped suddenly, etc.
Name one step of the Scientific Method that happens before conducting an experiment.
Observation, Ask a Question, Research, Hypothesis, Procedure
These variables are kept the same by the experimenter
Control variables
An experimenter wants to find out if wearing a seat belt affect the passenger motion when a car stops suddenly.
What is the dependent variable in their experiment?
Passenger motion
What is the last step of the Scientific Method?
Share results
This is the variable that the experimenter changes in the experiment.
Independent Variable
An experimenter wants to find out if wearing a seat belt affect the passenger motion when a car stops suddenly.
Give a possible hypothesis for this experiment.
If a passenger wears a seat belt, the passenger will have less motion when the car stops suddenly.
Name one part of the Scientific Method that happens after conducting an experiment.
An explanation for why something is the way it is that is supported by many different scientific experiments
Theory
An experimenter wants to find out if wearing a seat belt affect the passenger motion when a car stops suddenly.
Name two possible control variables in the experiment.
Speed before stopping, type of car, passenger height, passenger weight, weather conditions, type of road, fit of seat belt, tread on tires, many more possibilities!
