my method!

Method for my experiment.

Equipment:
-A packet of Calendula seeds
-5 pots
-Red cellophane
-Dark green cellophane
-Dark purple cellophane
-Orange cellophane
-Yellow cellophane
-Ruler
-Scissors
Method:
1. Fill each of the 5 pots with soil and plant 10 seeds from the packet into each of them.
2. Poke holes through each of the 5 sheets of coloured cellophane.
3. Wrap each pot with a different coloured cellophane.
4. Leave the pots in the same place outside.
5. Water the plants every day.
6. Measure the rate of plant growth every week.

Yeah, i think that's about it.
p.s taking care of plants is very tiresome );
