Scientific Method and Experimental Design

Forming a hypothesis

Drawing conclusions

Designing an experiment

Asking a testable question

What makes the sky blue?

Does changing the color of light affect plant growth?

How does the weather affect mood?

Why do plants grow?

A factor that can change

A constant factor

A hypothesis

A conclusion

The variable that is measured

The variable that is not used

The variable that is kept constant

The variable that is changed by the scientist

The variable that is changed by the scientist

The variable that is measured

The variable that is kept constant

The variable that is not used

By making it more complex

By using a hypothesis

By adding more variables

By identifying a cause and effect relationship

To change the outcome

To keep certain factors constant

To measure the dependent variable

To alter the independent variable

How does the type of paper affect the distance a paper airplane flies?

How do plants grow?

Why do birds sing?

What makes the ocean blue?

To ensure that the results are due to the independent variable

To make the experiment easier

To ensure the experiment is interesting

To allow for multiple independent variables

Change the hypothesis

Ignore the results

Change the dependent variable
