Independent, dependent variable, and writing hypothesis

Students want to test if changing the wing shape of a paper airplane  will affect  the distance it  will fly. What is the independent variable? 

• the wing shape 
• the distance the airplane will fly 
  dependent
• the temperature in the classroom 
• the type of paper used to construct the plane

Students want to test if changing the wing shape of a paper airplane  will affect  the distance it  will fly. What is the dependent variable? 

• the wing shape 
• the distance it will fly 
• the temperature in the room 
• the type of paper used to construct the airplane 

Students want to test if changing the wing shape of a paper airplane  will affect  the distance it  will fly. Which of the following is a good hypothesis for this experiment? 

• If the airplane fly for three minutes, then that will be the best design 
• If the wing shape is round, then the airplane will fly for more time 
• If the wing shape is wider, then the airplane will covered more distance 
• If the airplane is made of construction paper, then it will fly farther

Susie wants to know if an increase in temperature is accelerating the decaying process of apples. What is a good hypothesis for this experiment? 

• If apples are red, then the decaying process will be accelerated 
• If the apples are placed outside, then they will look fresh after three days 
• If the decaying process is accelerated, then the apples will look fresh and healthy 
• If the temperature is decreased, then the apples will look fresh for more time
