ALL PHOTOSYNTHESIS

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

Does it look like this experiment was set up properly?

• Yes - all three plants are the same

• Yes - all the lights are the same

• No - they should have given each plant different amounts of water

• No - they should have only changed one thing

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?

• What kind of light do plants grow best under?

• Can't tell - two things were changed, and there should have only been one thing changed

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

What is being tested in this experiment? What is the scientist trying to find out?

• What color of light causes plants to grow better?

• How much water should this kind of plant get to make it grow best?

• Can plants live without water?

• What kind of fertilizer causes plants to grow best?

What is the question that can be answered with this experiment?

• What kind of light do plants grow best under?

• What kind of plant uses the most water?

• Can't tell, because too many things were changed.

• How much fertilizer should plants get?

Is this experiment set up correctly?

• Yes, because only one thing was changed - the kind of fertilizer

• Yes, because water was used

• No, because all the plants are the same

• No, because each plant should have received different amounts of water

What question is being answered with this experiment?

• What kind of fertilizer causes plants to grow best?

• What kind of plant grows taller?

• How much water is the best amount for this kind of plant?

• What color of light is best for plants?
