Plants on the Move! Experiments with Phototropism

[kariyuana10]

I have a few questions:

What do I do for the plants while I am waiting for cup 1 go grow 3 cm? I was wondering if I need to water the plants while I am wating for them to grow.

Where do I store the plants while I am waiting for cup 1 to grow 3 cm. Do I put the plants in a dimly lit room ro do I put the under the grow lamp? Please advise.

I was also wondering I you may have an example of a chart or graph I can use for this experiment. Thanks.

Hi,

This is an excellent project. Cup 1 is grown in normal light under the grow light and is a control plant for this experiment. You should keep all of the plants watered during the experiment. The only variable should be the amount of light each plant is exposed to. The plants should be kept under the grow light during the experiment. You should take them to a dimly lit room once a day to open all of the cartons to measure the plants and record your observations.

I have not done this experiment, so I don't have an example of a graph showing the results. I would recommend graphing time on the x axis and cm on the y axis,

Let us know about your results, or if you have any other questions.
