2nd 6 Weeks Review - Science

What would the INDEPENDENT variable be in this experiment testing paper vs. construction paper: Does the type of paper an airplane is made of affect how far the airplane will fly?

• the type of paper used

• the model of paper airplane

• the distance of each plane's flight

• how hard the plane is thrown

What is a controlled variable?

• A variable being tested in an experiment.
• A variable that changes depending on another variable.
• A variable that is kept the same in an experiment.

Scenario: You want to test whether water helps to improve plant growth. What is the Independent Variable? (Remember: Independent Variables are what "I"change in the experiment.

• The growth of the plant

• Amount of Sunlight

• Amount of Water

Answer explanation

The amount of water is the independent variable because you are testing to see if water improves the growth of the plant. You are changing the amount of water given to each plant, so that you can see its effects on the plant.

An experiment is performed on plants to see how different liquids affect plant growth. Each plant in the experiment is given a different liquid; water, apple juice, or milk. Each plant has the same amount of soil, sunlight, and listens to the same music. In this investigation, what is the dependent variable?

• Type of plant
• Water, apple juice, milk
• Plant growth

An irregular shaped object was placed in a graduated cylinder. The initial volume was 50mL. The final volume was 75mL. What is the volume of the irregular shaped object?

• 25mL

• 125mL

• 75mL

• 50mL

In the water displacement method for finding volume

•  You subtract the final volume from the initial volume
• You subtract the initial volume from the final volume
• You add the initial and final volumes
• You divide the final volume by 2 

The density of an object is

• The mass divided by the volume D = m/v 
• The volume divided by the mass D = v/m 
• The same as its weight
• The same as the size of the object
