Scientific Method
This is the first step of the scientific method.
What are observations?
Observations that are focused on numbers.
What are quantitative observations?
This is a study where the scientists don't know which group is which during the study.
What is a blind study?
When two things happen at the same time, but don't necessarily imply causation.
what is correlation?
This is how a hypothesis is phrased.
What is an "if...then..." statement?
The color and texture of the sand on the beach is an example of this type of observations.
What is qualitative?
What is the sample size?
An idea about the world that is consistent and can be used to predict future events.
What is a scientific law?
The null hypothesis for a prediction that sunlight will make flowers brighter in color.
What is "There is no impact of sunlight on flower color brightness."
What is the control group?
Sample size should be ______ for more reliability.
What is larger?
what are constants?
The final step of the scientific method.
What is communicate and share/report your findings?
A class takes a test and scores are measured. Some students take the test in a cold room, some in a hot room, and some in a regular temperature room. These are the independent and dependent variables.
IV = room temperature
DV = student test scores
When scientists read a study and agree that it has strong methods and should be published.
What is peer reviewed?
A scientist finds that their hypothesis is not support. This is what they would most likely do.
What is retest or make a new hypothesis or do more research or adjust their methods?
On a graph, the x-axis and y-axis tell us about the variables of the study. Which axis is each variable usually on?
X = independent variable
Y = dependent variable
A controlled experiment in which the only thing changed is the independent variable can sometimes imply ___________.
What is causation?
