Students made paper airplanes using different shapes, but the same paper. Then, they launched them and recorded which went the furthest. What is the independent variable?

• the type paper used

• the type of paper airplane

• the distance of each plane's flight

• how hard the plane is thrown

Nick wanted to see how high an ice cube would float in different temperatures of water. He put the same size ice cube in a 50 mL of hot, room temperature and cold water. Then he measured the distance from the bottom of the cup to the ice cube. What is the independent variable?

• amount of water

• height of ice cube

• temperature of water

• size of ice cube
