Photosynthesis - Fair Experiments

Look closely at the setup of the experiment. Does it look like it was set up properly?

• Yes - all the plants are the same

• Yes - all the plants get some water

• No - the lights AND the water are different - only one thing should be changed

• No - they should have used all three different kinds of plants

Which question is the scientist trying to answer with this experiment?

• Under which color light do plants grow best?

• How much water makes the plant grow the best?

• Does fertilizer help plants grow better?

• Can't tell - there are two things changed when there should only be one.

Which question is the scientist trying to answer with this experiment?

• What kind of plant grows the best?

• How much water is best for plants?

Is this experiment set up correctly?

• Yes, because only one thing was changed - the light color

• Yes, because all science experiments have to have plants in them

• No, because the plants all should have different amounts of water.

• No, because the plants should not have received no fertilizer

Is this experiment setup correct?

• Yes - three different kinds of plants were used

• Yes - the lights were all different

• No - different light colors AND different plants were used - you are only supposed to change one thing in an experiment

• No - each plant should have received different amounts of water
