Hi Everyone,
I hope you'll enjoy this first article about osmosis:
An Easy Science Fair Project On Natural Water Pumps
(Osmosis)
For this science fair project we are still on the theme of
trees. In this one we are going to look at the way trees manage to take up
water, through its roots, to the highest branches. You can try sucking up water
or any other drink through a very long straw and you will find it very
difficult. Make your own long straw by joining together straws and try it.
Now our task with this easy science fair project is to
demonstrate the way trees manages to pump hundreds of pints of water a day.
This process is called osmosis. We are going to use two very easy experiments
to demonstrate the process of osmosis. The first one we are going to do in this
article and the next one in the following article.
The potato osmosis experiment
This is what you’ll need:
* One large potato
* A ruler
* A chopping board
* A peeler
* A knife
* A teaspoon
* Two shallow dishes
* Water
* Sugar
This is what you need to do for this science fair project:
(Please be careful with the peeler and knife, smaller children should let an
adult help.)
1. Carefully peel your potato on your chopping board.
2. Now you have to cut the potato in half.
3. Slice of the rounded part of both halves so that you have
a potato that can lie stable in your
dish.
4. With your teaspoon you now have to scoop out a hollow in
each potato half.
5. Now you have to place each potato half in a shallow dish.
6. Fill your shallow bowls with about ½ inch of water.
7. Now you also have to fill each hollow, in each potato,
half full with water.
8. To one hollow you now have to add about ½ a teaspoon
sugar.
9. Cover your potatoes and leave them for one day.
10. After a day you can make your observations.
11. What has happened?
12. Is the levels of water in both hollows still the same?
13. If not, what is the difference?
14. Why do you think it has happened?
15. Does the higher concentration of the sugary water have
anything to do with what has happened?
This experiment shows us how osmosis works. If we think about
our trees again; the water inside the roots has a higher concentration of sugar
as the water on the outside. Through the process of osmosis the tree draws
water from the soil, where the concentration is lower, to the inside of the
roots, where the concentration is higher, and that is how the tree pumps the
water from the soil to the leaves at the top.
