Scientific Method and Variables

A series of steps used by scientists to solve a problem or answer a question. 

• scientific method
• recipe
• data collection
• metric system

The information you collect while doing your experiment is called

• conclusions

• data

• hypotheses

• procedures

The variable that is being measured or observed is called the _______________. Hint: this is the variable that is the result or effect

• independent variable

• dependent variable

• control variable

What is a constant/control in an experiment?

• Things that do not change in a experiment. It's the variable that stays the same. You can have many variables stay the same.

• It's the variables that the scientist changes in the experiment

• It's the variables that are being measured in an experiment

A scientist investigates the effect of carbon dioxide on plant height. The scientist grows plants in several closed containers. All the plants receive the same amounts of water and light, but the air in each container has a different amount of carbon dioxide. What is the independent variable in this experiment?

• the amount of carbon dioxide in each container

• the number of plants in each container

• the amount of water provided to the plants

• the height of each plant after a period of time
