                    SCIENCE FAIR PROJECT IDEAS

Have you ever wondered what happens inside of an egg when it is hard
boiled?  Would larger eggs take longer to cook?  How hot does the water
have to be?  Will higher water temperatures make the eggs cook faster?

Why does salt melt ice?  Do you think that mixtures of different salts
such as calcium chloride and sodium chloride would work better?  Would
sugar melt ice, or chalk?

Some ant-acid tablets like Tums claim they work better than other
products and that they contain calcium.  How could both of these claims
be tested?  Do some tablets contain magnesium or aluminum?

Some people dye their hair.  How long does it take for the dyeing to be
completed?  How long will the dye last?  Which brands are better?  What
chemical reactions occur during the bleaching or hair using peroxides? 
Will different types of hair react differently?

You may use a hair spray.  What chemicals are present in sprays?  Do
that resemble glues?  Will that dissolve in water?

How do products like Bounce act to soften clothes after they are washed
and dried?  What happens when clothes are ironed to stiffen them and
take out wrinkles?

Some shampoos contain both a conditioner and shampoo.  Some are single
products. What chemicals do each contain?  Why do they work?  Can you
mix  a conditioner and a shampoo in the same bottle and get the same
results as with the combination product?

Some paper is slick and shiny while other paper is rough.  Is all paper 
the same chemically?  if you use a pen on different types  of paper will
the ink stick as well or will it stain?

Do you use anti-perspirants?  How do they work chemically?  Do they
absorb water or tighten the skin?  Can some chemicals help to keep
things dry?  Have you ever found a little  package inside of potato
chips, or in electronic equipment packages to keep water out?

You're heard a lot about acid rain.  Do you think there is acid snow or
ice as well?

Breakfast cereals contain iron.  Could you detect iron metal powder if
it was present in the cereal?  Do you think powdered iron is really good
for you?

Tungstem metal is used as the filaments in some light bulbs. How could
you test this?  Why is tungsten used and not iron or magnesium
(Magnesium is actually used in a special type of bulbs.  Do you know
which?)?

The ink used in washable markers is different from the ink used in
permanent marking pens.  How do they differ chemically?  Is washable ink
really easy to remove?  Does it get harder to clean after a certain
amount of time?
