Name 2 similarities between pseudoscience and science.
Science and pseudoscience are both related to the world and they both use empirical evidence.
200
What is the dependent variable?
The dependent variable changes as a result of the independent(manipulated) variable.
200
What are facts?

Describe the difference between pseudoscience and science.
Pseudoscience does no use the Scientific Method and its measurements may be vague.
300
An investigation that has been done by more than one scientist with similar findings has been _______.
replicated

Name the difference between a theory and a law.
A theory describes why something happens while a law states what happens.
400
What is the difference between accuracy and precision?
Accuracy is the description of how close to the true value you are, while precision is the exactness of the measurement.

What do each of the 3 models do?
Physical Model : scale models to approximate distances
Mathematical Model : finding patterns and making predictions
Conceptual Model : figure out how parts are related and similarities for classifications.
500
How can pseudoscience become science?
Pseudoscience may become science when technology advances and there is evidence to back up the theory. This makes it science.
500
Name the steps to the scientific method.
1. Make an observation
