I CHANGED the amount of water that was added to each test group. This is known as a :

• Constant

• Control

• Independent variable

• Dependent variable

A student is testing to see if the amount of water affects seed growth. Which of the following is a hypothesis for this experiment?

• The seeds that receive the most light will grow faster.

• Different types of seeds will grow at different rates

• Temperature changes will cause some seeds not to grow

• The seeds with the most water will show the most growth

In an experiment, the differences that YOU CREATE between the group is called the:

• Independent variable

• Dependent Variable

• Constant

In an experiment , the difference MEASURED in the results

is the :

• Independent Variable

• Dependent Variable

In this experiment, seeds were either given salt or fresh water. After 3 weeks, the growth was measured.

What is the independent variable?

• The number of seeds

• The type of water the seeds received

• How much the seeds grew

• The amount of light the seeds received
