Multiple Choice

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

Multiple Choice

Students want to test if changing the wing shape of a paper airplane will affect the distance it will fly.

Which one 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 cover more distance

• If the airplane is made of construction paper, then it will fly farther

Multiple Choice

Saydi wants to do an experiment that looks at how the amount of baking soda to a baking soda and vinegar reaction will affect how long the reaction creates bubbles.

What is the independent variable?

• the reaction

• the amount of vinegar

• the amount of baking soda

• the time that the reaction makes bubbles

Multiple Choice

Saydi wants to do an experiment that looks at how the amount of baking soda to a baking soda and vinegar reaction will affect how long the reaction creates bubbles.

What is the dependent variable?

• the reaction

• the amount of vinegar

• the amount of baking soda

• the time that the reaction makes bubbles

Multiple Choice

Saydi wants to do an experiment that looks at how the amount of baking soda to a baking soda and vinegar reaction will affect how long the reaction creates bubbles.

Which of the following is an appropriate hypothesis for this experiment?

• If the vinegar is added, then the reaction will make bubbles

• If the amount of baking soda is more than the amount of vinegar, then the reaction will make bubbles for a longer time because there will be more vinegar molecules to continue the reaction.

• If the baking soda is cold, then the reaction will make bubbles for less time.

• If the reaction happens, then there will be a mess to clean up because it will spill onto the counter
