The Scientific Method

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

• constant

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. What variables should be kept constant/controlled? 

• type of plant, flower pot,  soil, and amount of sunlight
• water, apple juice, milk
• only the amount of sunlight
• type of plant only

What is being kept constant?

• how fast the water boils

• amount of water

• temperature of stove

• Mr. Considine says NO

What is being measured or the result/effect of this experiment?

• how fast the water boils

• amount of water

• temperature of stove

• Mr. Considine says NO

What is being changed in this experiment?

• temperature of the stove

• how fast the water boils

• amount of water

• Mr. Considine says NOT THIS ONE

What is being kept constant?

• ramp height

• speed of the ball rolling

• type of ball

• Mr. Considine says NAAAAAAHH

What is being measured or the result/effect of this experiment?

• ramp height

• the speed that the ball rolls

• type of ball

• Mr. Considine says TRY ANOTHER CHOICE

What is being changed in this experiment?

• ramp height

• the speed that the ball rolls

• type of ball

• Mr. Considine says YOU SHOULD PREPARE FOR YOUR EXAM TONIGHT!

The summary at the end of an experiment that explains the results is called the ___________________

• conclusion
• procedures
• materials
• responding variable

What is a constant/control in an experiment?

• Things that do not change inana 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

• Mr. Considine says LOOK ELSEWHERE
