Hi Everyone,
I hope you have fun with this experiment:
Elementary Science Fair Project - Growing Seed Science Fair
Project
In this elementary science fair project we are going to try
and find out what seeds need to grow. Can you think of a few things that are
essential for seed to start growing? Write down your answer and that is called
your hypothesis. When you have completed your elementary science fair project
you will know if you were right and the results will lead to your conclusion
that is the decision you make, on what is necessary, based on your results. For
more on scientific method you can have a look at 24 Hour Science Projects. In
24 Hour Science Projects you get complete science fair projects that can be
done in 24 hours or less.
Now on to our experiment
What you need:
- 6 Small sealable plastic bags
- A pair of scissors
- A Packet of radish seeds (you will need 36 seeds)
- 3 Paper towels
- Water
- Felt-tip marker
- A bottle of nail polish
The how to:
1. Start by marking each of your plastic bags numbers 1
through 4.
2. Cut all your paper towels in two. One of the pieces you
will not need.
3. Now you have to moisten 5 of your pieces of paper towels.
4. Your fifth piece must be left dry.
5. Now you have to place the towels in the bags as follows:
a) In 4 bags place moist paper
towels
b) In one bag place a dry towel
c) In one bag you do not place a
towel but you put some water in the bag.
6. In each bag you now place 6 radish seeds
7. Now you do the following with each bog:
i) Place one bag with a moist towel
in a place without any light like a drawer.
ii) Place another bag with a moist
towel in, in a light place at room temperature.
Iii) Another bag with a moist towel
you keep in a place that has not light and is very cold, the freezer.
iv) Place one bag with a moist
towel in, in a place that has no light and at room temperature, but cover the
seeds with nail polish.
v) Place the bag with the dry towel
in the light at room temperature.
vi) Lastly you place the bag
without a towel in a light place at room temperature; these seeds are now
floating in the water you placed in this bag.
8. Now you have to record the date that you have started
with your elementary science fair projects.
9. Check all your bags twice a day and record what you see
happening.
Now this is what you will see happening:
1) You will see that the seeds in bags i & ii starts to
grow. (Germinate)
2) In bag vi you may see some difference in the seeds. Keep
checking it and write down exactly what you see.
3) In the other bags the seeds do not start growing. Can you
give a reason for this? Think about it and write down what you think, after
this we are going to look at the reasons.
Seeds need very specific conditions to be able to grow.
Seeds do not need light to germinate, as they mostly
germinate underground. Late on, however, they do need light to grow. You can do
an experiment with this by placing the one set that has started growing in a
light place and the other in a dark place, but this is not within the scope of
this science fair project.
Seeds also need oxygen to be able to grow, so that is why
the seeds covered with nail polish did not grow, they could not get any oxygen
or any water! The seeds also need to be moist in order to be able to germinate,
but the seeds in the bag with only water, were also not able to grow because
they were practically "drowning" in the water. They cannot get any
air and the amount of water probably will cause them to rot. Too much water is
also wrong.
Enjoy your day,
Jacob
