Terms 1
The procedure scientists use to help them explain why things happen is called...?
What is the scientific method?
These are what you don't change during an experiment.
What are controlled variables (or constants)?
Experiments should always be repeated.
What is true (to rule out any errors)
"The juice is sour" is a qualitative or quantitative variable?
What is qualitative?
This is what you're trying to find out. It's always written in the form of a question.
What is the problem?
Describe the difference between qualitative and quantitative observations.
Qualitative observations involve qualities (use senses to describe), quantitative observations are quantities that involve numbers
Inferences can be completely random.
What is false (they should make sense based on observations)
If you throw three different paper airplanes with the same force but they travel different distances, what is the responding (dependent) variable?
What is the distance they travel.
The two different types of observations are known as?
What are qualitative and quantitative?
These are what you change during the experiment.
What are independent variables (manipulated variables).
The "plant is long" would be example of a quantitative observation.
What is false (there are no numbers involved, this can be seen using senses)
If you're looking at a picture of a smiling child playing in the sand, which would be the observation: the child is smiling or the child is at the beach?
What is the child is smiling (assuming they're at the beach is an inference, the sand could be at a playground)
This is a conclusion that is made after making observations.
What is an inference?
This is the step for the scientific method when you analyze data and summarize findings.
What is the conclusion?
Variables in an experiment always change.
A scientist hypothesizes the the temperature at which an alligator's egg is incubated will determine whether the alligator will be male or female. Name the independent variable.
What is the temperature of incubation.
This is an educated predication about what will happen in your experiment.
What is a hypothesis?
These change in response to the manipulated variable.
What are dependent variables?
Experiments often test multiple variables.
What is false (experiments should test one variable)
A scientist hypothesizes the the temperature at which an alligator's egg is incubated will determine whether the alligator will be male or female. Name the dependent variable.
What is the gender of the baby alligators.
