Begins with a question
What is a hypothesis?

any factor, trait, or condition that can exist in differing amounts or types
Variables
The information gathered from observations and experimentation is called
Evidence or Data
What is the statement that answers the question called?
A claim of a conclusion
What comes after researching your topic?
Formulating a hypothesis that can be tested.
What 2 words should always be in your hypothesis statement?
If, Then

Bryson loves candy, but is worried about the amount of sugar he is consuming. He gathered 5 of his favorite candies and read the nutrition labels to see how many grams of sugar were in one serving of each candy. He used a cube of sugar for each gram the candies contained and put them in baggies to compare them. What step of the scientific method is he on?
Research
what changes as a result of the independent variable manipulation in experiments (what we measure)
dependent variable.
What two steps review the data collected?
Analysis and interpretation (drawing conclusions)
What is one benefit from sharing your results with others?
You can get feedback.
Scientists are the only individuals who use the scientific method True or False
False - WE ALL USE IT
