Plant Experiment:
Aim of the Experiment:
To find out if microwaved water affects the
germination and/or growth of the Brassica
rapa
Apparatus:
·
20
sponges
·
20
Brassica rapa seeds
·
1
measuring cup
·
1
microwave
·
1
boiler
·
1
ruler
Steps of Experiment
1.
Separate
the 20 sponges into 2 groups of 10 each.
2.
Label
each sponge accordingly. Control sponges are known as “C” followed by
stipulated number, while sponges testing the variable are known as “M” followed
by its stipulated number.
3.
Ensure
that the control sponges are moist with the amount of water stipulated in
Experiment #1, and this water is boiled.
4.
Ensure
that the microwaved sponges are moist with the amount of water stipulated in
Experiment #1, and this water is microwaved.
5.
Place
each Brassica rapa seed in each
sponge, ensuring that each seed is embedded 3 millimetres deep in the sponge.
6.
Place
each sponge in rows by the window to ensure enough sunlight for photosynthesis.
7.
Once
every week, on the stipulated day at the stipulated time, boil and microwave
water. For boiled water, ensure that the amount of water boiled is 10 times the
stipulated amount of water in Experiment #1. Likewise for microwaved water.
8.
Water
the Brassica rapa grown on the
control sponges at the base of the stem with boiled water. The boiled water is
of the stipulated amount in Experiment #1, and the amount is measured out by
the measuring cup.
9.
Water
the Brassica rapa grown on the
control sponges at the base of the stem with microwaved water. The microwaved
water is of the stipulated amount in Experiment #1, and the amount is measured
out by the measuring cup.
10.
Keep
a log of any changes observed in each seed, including appearance of root. Take
photos of each seed every day for easier comparison at end of experiment.
11.
Do
not replace any dead plant; record death in log.
12.
Conclude
the experiment on 24 June, last day of the holidays. This deadline is decided
based on time constraints from hectic school schedule, rendering conductor of
experiment unable to care for the Brassica
rapa and record changes observantly.
13.
Collate
data.
