Qualitative
Name a step in the scientific method

Draw conclusions
Create a hypothesis for the following experiment:
A scientist wants to know if mice run a maze better with cheese at the end or not. He has 5 mice run a maze without cheese at the end and 5 mice run a maze with cheese at the end
If the mouse smells cheese, it will run the maze better because it smells the cheese at the end.
