In science, what is a scientific theory?                               

• the first idea to explain an observation 
• the best idea to explain a hypothesis 
• an explanation for many hypotheses and observations
• an explanation for many questions and answers 

What is the advantage of creating a model of a dinosaur?

• they are too large to easily study 
• they are too complicated to study
• Real dinosaurs cannot be studied because they are extinct
• The model is safer to work with. 

All of the statements below are correct except one. Mark the one that is incorrect.

• Models must be exactly like what is being modeled.
• Models communicate information.
