An experiment that tests only one factor at a time by using a comparison of a control group with an experimental group.
What is a controlled experiment.
True or False
The steps of the scientific method are the same
What is TRUE
A good hypothesis is ? (2 things)
What is testable and based on observations
True or False
More than prediction may be made for each hypothesis.
What is TRUE
Scientist always try to test MANy individuals. The more organisms tested the the more certain....
scientists can be of the the data they collect in an experiment.
A series of steps followed to solve problems.
What is the scientific method
True or False
The steps of the scientific method are always used in the same order.
What is false
What makes a hypothesis testable?
If you can design an experiment around it
After Scientists make predictions they?
What is test the hypothesis (create an experiment)
Scientists can support their conclusions of experiments by?
Repeating their experiments
The study of living things.
What is life science
Any information that we gather through our senses is an _________________.
What is an observation
True or False
Scientists may form more than one hypothesis for the same problem?
TRUE
To sort out factors, scientist perform ____________________________.
What is a controlled experiment
True or False
A scientist's work ends when an experiment is finished.
What is FALSE
A factor that changes in an experiment in order to test a hypothesis
What is a variable
3 tools or methods that scientists use to make and record observations are?
What are microscopes, rulers, and themometers
A statement of cause and effect that can be used to set up a hypothesis is a ____________________
What is a Prediction
All factors for the control group and experimental group are the same except_____________.
What is ONE (factor)
After a scientist has analyzed the data from several experiments they do what?
What is draw conslusions
An explanation that is based on prior scientific research or observations and can be tested.
What is a hypothesis
The first step of the scientific method is ?
What is an observation
Predictions are often stated in what format?
provide an example.
An if-then format
EX. if a substance in the pond water is causing deformities, THEN the water from ponds that have deformed frogs will be different from the water from ponds in which no abnormal frogs have been found.
The one factor that differs in an experiment is called the __________________________.
What is a Variable
Is is wrong or bad if a scientists hypothesis is wrong?
No- they can learn learn what from learn and/or create a new hypothesis if necessary
