Science Fair Projects Kids Will Enjoy Part Seven – Static Electricity

24 Hour Science Projects

Here is part seven of our Science Fair projects Kids Will Enjoy about static Electricity. In this experiment we are going to see how to objects that are negatively laden are attracted to objects that are positively laden. Once the objects are no longer negatively laden, they are not drawn by a positively laden object any more.

Remember for a full science project you will have to combine this whole series, so, I hope you have time to wait for them all! If not, there is a very good solution for you, go to 24 Hour Science Projects; there you will find complete science fair projects you can do in 24 hours or less! So, if you are in a hurry, go to 24 Hour Science Projects now!

Here are our science fair projects kids will enjoy:

Remember, for all science fair projects you have to make notes of everything you do, why you do it, what you are trying to prove or demonstrate and your conclusion. It is always a good idea to take photos for your exhibition.

The case of the dancing paper dolls:

What you need for your experiment:

Two books
A glass disk
A metal plate
Two books
Tissue paper dolls about 3cm tall (cut any way you prefer as long as they not too big)
A woolen cloth

How to do your experiment:

Cut out your paper dolls (about 3-4)
Place two books a little way apart with the metal plate between them
Place the glass disk over them to be over the metal plate
Place the paper dolls in the metal plate
What happens when you place the paper dolls on the metal plate under the glass disk?
Now rub the glass disk with the woolen cloth for a few minutes
What happens?
Why does it happen?

By rubbing the glass disk with the woolen cloth it is loaded with electron to make it negative
Now the disk draws the positively laden paper dolls and they are also loaded
Now they drop down and the metal plate draws the electrons from them, once again making them positive
Now the glass draws them again and so the dance continues

I think this can be quite a good display for your friends to admire!

This is the seventh of our short series of science fair projects kids will enjoy. Look out for the others as doing all these experiments as one will probably be the best way of doing a thorough science fair project.

If you want to make sure you do a really winning science fair project; go to 24 Hour Science Projects now! Access is instant; your project can be ready tomorrow.

Science Fair Projects Kids Will Enjoy Part Six – Static Electricity

24 Hour Science Projects

Here is part six of our Science Fair projects Kids Will Enjoy about static Electricity. In this experiment we are going to see how to a spoon, laden with static electricity, will draw puffed wheat or rice to it. Opposite to a negative and a negative “pushing” each other away as in our previous example.

Here are our science fair projects kids will enjoy:

The case of the plastic spoon and the puffed wheat or rice:

What you will need for this experiment:

A bowl of puffed wheat or rice
A plastic teaspoon
A wooly sweater

How to do your experiment:

Without doing anything to the spoon, keep it just above the bowl of puffed wheat or rice.
What happens?
Rub the spoon on your sweater for a few minutes to load it with the extra electrons until it is negative.
Now hold the spoon just above the bowl of puffed wheat or rice.
What happens?
Keep the spoon there.
Why does it happen?
What happens after a short while?
Why does it happen?

After you have done all the previous science projects, you should be able to explain what happened here. Remember you should be able to give a scientific explanation for every step and why you are doing it.

Have a look at all our other science fair projects kids will enjoy to see how the whole process follows one on the other. It is important with these science fair projects kids will enjoy to do them all to make a complete science fair project. If you are in a hurry, go to: 24 Hour Science Projects now! There you will find complete projects that can be done in 24 hour or less.

Examples of Science Fair Projects – Temperature changes

For more examples of science fair projects you can visit Easy Science Fair Projects.

This is one of our examples of science fair projects that is very easy and are suitable for elementary school kids. We are going to use sand to represent the land and water the ocean. It is going to show us why temperatures close to the sea is more moderate. Winters close to the sea tends to be milder than inland. Humidity can also influence how hot it feels. In more humid conditions it feels hotter, even though the temperature is the same.

Now on to our measuring temperature experiment

What you need for this experiment:

Sand
A jug of water
Two bowls
A thermometer
A note book
A pen

How to do your science project:

Pour water into one of the bowls and sand into the other bowl. It is not necessary to measure the quantities exactly it must just be more or less the same quantity.
Now you have to place the two bowls in a cool place together.
Leave them there for a few hours.
Measure the temperature of both, make sure it is the same otherwise leave it for a while longer until they are the same temperature.
Make a note of the temperature.
Now you have to place both bowls in a sunny and hot place for about two hours until they are very hot.
Measure and record the temperatures of both bowls and make a note of it.
Put both bowls in a cool place indoors.
Now you have to measure the temperatures of the water and the sand every 15 minutes and write it down in your not book.
You should notice that the sand cools down much faster than the water.
You can also dip your hands in both and feel the difference. You can make a note of it as well but, of course your real evidence is not what you feel but the temperatures you recorded.
Why is it that there is a difference?
Where does the heat come from?

This is a very easy science fair projects and is also one of our examples of science fair projects that is very suitable for homeschooling. If you need more examples of science fair projects, you can visit Easy Science Fair Projects.
