What is a hypothesis?
A testable question for an experiment or observation
What does the scientific method start with?
A problem or question
What is scientific knowledge?
Knowledge that emerges from the empirical testing of hypotheses where evidence is verified against observations and experiments
What is a scientific theory?
A well tested explanation that is supported by evidence
What is a benefit of models?
They help visualize things that are too small/large/dangerous
What are other types of scientific investigations?
Field studies, models, and observations
What is the final step of the scientific method?
Conclusion
What is empirical evidence?
Evidence based on observations and measurements
What is a scientific law?
A statement that describes what will happen in nature every time
What is a limitation of models?
They aren't exact copies of reality
Does all scientific knowledge come from experiments?
NO YOU LITTLE CORNBALL
What do you need to do BEFORE you can make a hypothesis?
Do research
Can scientific knowledge change?
Yes, when new evidence is discovered scientific knowledge can change

Scientific Law: Law of Gravity, Newton's First Law of Motion, Newton's Second Law of Motion, Law of Conservation of Mass, Law of Conservation of Energy
You make a model of the solar system. What type of model is this?
A planetary/spacial/physical/scale model
What does an experiment need to have?
An independent variable(IV), dependent variable(DV), controlled conditions, and variables being tested
What do you need to do BEFORE you can collect data?

Does scientific knowledge require debating, testing, and confirmation?
Yes
Can a scientific law become a scientific theory?
No

What's the difference between repetition and replication?
Repetition is multiple trials completed by the SAME SCIENTIST
Replication is an experiment repeated by a DIFFERENT SCIENTIST
