Science Skills
What is qualitative?
Any factor that is measured to gather results.
What is a dependent variable?
The best type of investigation to determine which birds are most visible in an area.
Is the phrase, "There is a fire truck in the parking lot", an observation, an inference, or a prediction?
What is an observation?
The first step of the scientific method.
What is a question (purpose or problem)?
Theories or laws are an explanation for how things in nature occur.
What are theories?
A variable that is being changed or manipulated.
What is an independent variable?
When a scientist repeats their investigation multiple times.
What is repetition?
The phrase, "There is smoke coming from the building and a fire truck in the parking lot means that the building must be on fire" is an example of an observation, inference, or prediction.
What is an inference?
What is the hypothesis?
Theories or laws are observations of patterns in the natural world.
What are laws?

What is the prairie dog population?
When a scientist performs the same experiment as another scientist.
What is replication?
The phrase, "The sky is turning dark. There is thunder and lightning. I think it will rain." is an example of an observation, inference, or prediction.
What is a prediction?
A graph or chart is often used in this step of the scientific method.
What is analysis?
There were three people at the birthday party is an example of either a qualitative or quantitative observation.
What is quantitative?
Identify the dependent variable in the following scenario: The travel time depends on how fast I drive.
What is the travel time?
When a scientist needs to test something that is too large, too small, or too complex, they may use one of these.
What is a model?
The phrase, "When you walk into your classroom, you see a person that you don't recognize at the teacher's desk" is an example of an observation, inference, or prediction.
What is an observation?
The step where you summarize your results and restate your hypothesis.

What is quantitative?
In the following scenario, "My skill level in softball is determined by how much I practice", how much I practice is either the dependent or independent variable.
What is the independent variable?
A type of controlled investigation that has a variable.
What is an experiment?
The phrase, "I heard thunder earlier in the day and when I walked outside I saw that the ground was wet so I think it rained." is an example of an observation, inference, or prediction.
What is an inference?
The step where scientists share their results with other scientists.
What is communicate results?
