What is the technique for investigating phenomenon.
(Summarized (usually) into 6 steps)
The Scientific Method
The ________ ________ is what you, the experimenter, changes or enacts in order to do your experiment
Independent Variable
__________ is a push or a pull
Force
Who is credited with developing Newton's laws of motion
Sir Issac newton
What is the 1st step in The Scientific Method
Ask a question
This variable is
What you measure (Effect, After, Output, What happens)
Dependent Variable
___________ is the force that opposes the sliding motion of two surfaces that are touching each other.
Friction
•Force equals mass times acceleration.
F=ma
Newton's 2nd Law of Motion
Would you analyze your data BEFORE OR AFTER you test your hypothesis (experiment)?
After
If students spend more time using TikTok, then they will read fewer books.
(Identify the dependent variable)
Number of books read
When all forces acting on an object are equal is called
(Hint: There is NO MOTION)
Balance Force

Step 2
AFTER you ask your question
Students in Mrs. Dodson's class were split into two groups and each received a different textbook for a course. One group received a normal textbook, while the other received an interactive textbook. After the course, the final exam grades between the two groups of students were compared.

One group of students read a reading passage in silence and one group read the same passage with the TV on in the background. They both took a comprehension test to see what they understood from the passage and the results were compared.
(Identify the dependent variable)
Reading in silence or with tv on/ noise or no noise

_______ ________ is a force that keeps an object at rest
Static friction
•An object at rest will stay at rest, and an object in motion will stay in motion at constant velocity, unless acted upon by an unbalanced force.
