Multiple Choice

Your teacher has asked you to explain the difference between quantitative and qualitative observations. Which statement is correct?

• Quantitative observations use numbers, qualitative uses the senses.
• Quantitative observations use the senses, qualitative uses numbers.
• Quantitative observations use measurement, qualitative uses numbers.
• Quantitative observations use colors, qualitative uses the senses.

Multiple Choice

What is a hypothesis?

• the thing changed on purpose in the experiment

• an explanation about what you observed

• using your 5 senses to gather data

• an educated guess about the outcome of an experiment

Match

Match the correct IF with the THEN to form a proper hypothesis

perform better than those that don't

Then I will fail my test

Then they might show aggression

Then the economy will benefit

• perform better than those that don't

• Then I will fail my test

• Then they might show aggression

• Then the economy will benefit

Multiple Choice

A hypothesis is never wrong.

• True

• False

Multiple Choice

The variable that is measured.

• Controlled Variable

• Dependent Variable

• Independent Variable

Multiple Choice

The one factor that a scientist changes during an experiment.

• Controlled Variable

• Dependent Variable

• Independent Variable

Multiple Choice

Identify the dependent variable:
A study was done to find if different tire treads affect the braking distance of a car.

• The car
• The distance the car took to brake 
• The different tire treads
• The drive

Multiple Choice

Identify the independent variable:
The height of bean plants depends on the amount of water they receive. 

• The bean seed
• The amount of water provided daily
• The amount of sunlight they're exposed to daily
• How tall they grow by the end of the experiment

Multiple Choice

How many independent variables can be tested in a controlled experiment?

• one
• two
• three
• as many as possible

Multiple Choice

What is CONSTANT VARIABLE?

• Variables that remain constant

• A variable that is changed in an investigation.

• A variable that is observed in an investigation.

Multiple Choice

In an experiment, constants should always be

• different

• the same

• kind of the same

• none of the above

Multiple Choice

What is the term for things that remain constant in an experiment?

• Dependent variables

• Controlled variables

• Independent variables

• Controls

Explanation Slide...

In an experiment, 'Controlled variables' are the ones that remain constant or unchanged. The question asks for the term for things that stay the same, thus the correct answer is 'Controlled variables'. Other options like 'Dependent variables', 'Independent variables', and 'Controls' do not fit the context of the question.

Multiple Choice

What is the control for the experiment? 

• the thing being tested
• the normal situation
• what we measure in the end
• what we change 

Multiple Choice

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 are the controlled variables or constants?

• Amount of soil, sunlight and music
• type of liquid
• Plant growth
• plant given no liquid

Multiple Choice

• x-axis

• y-axis

Multiple Choice

The dependent variable goes on the:

• x-axis

• y-axis

Multiple Choice

• Bar graph

• Pic chart

• Scatter plot

Multiple Choice
