Goal Sheet Please place

in front of your binder!

Keep your goals in mind throughout the quarter.

“Our lives are not determined by what happens to us but by how we react to what happens, not by what life brings to us, but by the attitude we

bring to life. A positive attitude causes a chain reaction of positive thoughts,

events, and outcomes. It is a catalyst, a spark

that creates extraordinary results.”

Independent Variables

• What is tested by the scientist• What is changed by the

scientist• Also known as manipulated

variables.

Dependent Variable

• What is observed• What is measured• The effect caused by the

independent variable.• The data• Also called responding variables

Controlled Variables

• Things that could change but don’t

• Kept constant (the same) by scientists

• These allow for a fair test.
