• A random guess a scientist makes

• A historical analysis of science

• A personal view that a scientist has

What is a hypothesis?

• A proposed explanation for a phenomenon; based on observations or previous experiments

• An uneducated guess or prediction; not based on observations or other science

• A random guess to solve a problem

What is a variable?

• A factor or condition in an experiment

• A constant value that cannot be changed
