1.
First, gather all your materials.
2.
Then, chose a safe area suitable without any hazards to perform
your experiment.
3.
Take three pots of the same size, and fill them up with 4/5 of soil
close but not quite at the brim.
4.
Now, take one pack of the three types of plants chosen.
5.
Say you chose the chives. Open it and take 3-4 seeds to plant. Sow
them 15mm into the soil.
6.
For the mint leaves, take approximately the same amount of seeds
and sow them 15mm in the soil.
7.
For the bean plant, take one seed and also plant it 15mm deep. If
you do not chose to plant chives, mint leaves or a bean plant, then read
and carefully follow the directions on the package that they come in.
8.
Now, you’re ready to put on the green roof. You can use an aquarium
or a plastic bag. If you use an aquarium just simply put it over the pot
properly centered. If use chose to use a plastic bag version for the green
roof, put it over the pot and tuck the un-needed plastic under the bottom
of the pot. Make it so the pot is in a closed area. If you chose to use
plastic bags make sure all three plants use plastic bags. Same thing for
the aquariums.
9.
Measure the temperature of each plant. Record the temperature.
10.
Then after 3-4 hours, mix baking soda with baking soda in a cup
(carbon dioxide), and place one mixture inside each
plant.
11.
Measure the temperature after adding the CO2 mixture. Record each
temperature.
12.
Repeat steps 9-11 every 3 days.
13. Every
odd day, water 40ml of water to each plant.
14.
Then every even day measure the water absorption of each plant. To
measure the water absorption you must, first take a soil sample from each
of the pots of soil using a tablespoon. Then, use a weight scale to
individually measure the weight of the soil sample. Remember this before
the water is added. Then after the water is added, wait a day. Then,
take a soil sample in the same place as you did last time, and the SAME
AMOUNT. Now, measure the weight of each soil sample. Record your results.
15. Everyday,
use a ruler to measure the daily growth of each plant. Record the growth
in mm.
16. Repeat steps 9-15 for an experimental
period of 15 days.
