Science Projects
(Recommended for 2005-2006 school year)
| Air Battery/ Saltwater
Battery
In this project you will experiment
making electricity using a revolutionary method. You may call this air
battery because it uses the oxygen from the air. You may also call it
salt water battery because it uses a solution of salt water as electrolyte.
The electricity you produce can be
high enough to light up a light bulb. You can extend the power by
adding oxygen. |
 |
|
You can also perform
experiments to see how does the amount of salt, the amount of oxygen,
or the size of electrodes affect the amount of electricity or the
battery life. Write your results in a table and use them to draw a
graph. Recommended for ages 11 to 18. This is an experimental (investigatory)
project. [See More Details] |
| Wooden Generator
In this project you will experiment
making electricity by spinning a magnet inside a wire coil. This is
the principle of electric generators. Make all parts using wood; only
the magnet and wire will be non-wooden material.
The electricity you produce can be
high enough to light up a light bulb; however, it will just flicker if
you spin the magnet by hand. |
 |
| You can also
perform experiments to see how does the number of wire loops or the
diameter of wire affect the amount of electricity it produces. This is
an experimental (investigatory) project. Recommended for ages 13 to
18.[See More Details] |

Fruit Battery
(Make Electricity From Fruits)
Even fruits can make electricity and
if you be lucky, you may even get enough electricity to light up a
light bulb. The electricity produced by fruits can easily be measured
using a multi-meter. In this project you compare different fruits for
the amount of electricity they can produce. Find out if sour taste and
acidity of fruits can contribute to the production of
electricity.
This project is a safe version of
other battery projects that use corrosive chemicals. |
 |
The
electricity from fruits is important because it also indicates the
concentration of minerals available in fruits. You can also use this
method to compare the quality of different potatoes or different
oranges. This is an experimental (investigatory) project.
Recommended for ages 10 to 16. [See

| Make a DNA Model
DNA is a nucleic acid that contains
the genetic instructions specifying the biological development of all
cellular forms of life. By changing parts of DNA, scientists are able
to produce plants, animals and other live organisms with new properties
and abilities. Genetically modified crops and genetically modified
fruits are widely known and used.
For students who like biology and
want to understand the structure of DNA, making a DNA model can be an
exiting display project with special learning benefits. |
 |
| A model can
simply be made using foam balls. This can be a complete display
project or an addition to any DNA related project. [See

| Starch test kit
In this project you will test different
foods, fruits or products for presence of starch. Find out how widely
the starch is used in different industries. You may expand the starch
test topic to many new project ideas. For example you may research the
effect of sunlight in production of starch or the effect of enzymes on
starch. |
 |
Determination
of starch in foods is important due to dietary concerns of many people
who are on a low starch/ low sugar diet. This is an experimental (investigatory)
project.
Recommended for ages 10 to 16. [See
