Question

1. i am experimenting to find out how far different paper airplanes fly. i will make 3 different types of paper airplanes. i will throw each paper airplane and measure how many meters it flies before it hits the ground.

independent variable:
dependent variable:
hypothesis:

1. i am experimenting to find out how long it takes a ball to fall from the roof. i will drop a baseball, a football, and a soccer ball from the roof. i will measure how many seconds it takes for each ball to hit the ground.

independent variable:
dependent variable:
hypothesis:

1. i am experimenting to find out what the favorite colors of the students at wakefield hs are. i will ask 500 students to choose red, blue or yellow. i will measure the number of wakefield hs students that choose each color.

independent variable:
dependent variable:
hypothesis:

Explanation:

1.

The independent variable is the type of paper - airplane as it is being manipulated. The dependent variable is the distance it flies as it is being measured. A possible hypothesis could be: The type of paper - airplane affects the distance it flies.

The independent variable is the type of ball as it is being changed. The dependent variable is the time it takes to fall as it is being measured. A hypothesis could be: The type of ball affects the time it takes to fall from the roof.

The independent variable is the color as it is the factor being varied. The dependent variable is the number of students who choose each color as it is being counted. A hypothesis could be: The color affects the choice of students at Wakefield HS.

Answer:

Independent Variable: Type of paper - airplane
Dependent Variable: Distance the paper - airplane flies
Hypothesis: The type of paper - airplane affects the distance it flies
