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.

Science Fair Projects Kids Will Enjoy Part Five – Static Electricity

Science Fair Projects Kids Will Enjoy Part Five – Static Electricity

24 Hour Science Projects

Here is part five 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 “push” each other away. Opposite to a negative and positive drawing each other.

Here are our science fair projects kids will enjoy:

The case of the hostile balloons!

What you will need:

2 Balloons
2 pieces of string
A wooly sweater

How to do this experiment:

Blow up both balloons as much as possible without bursting them
Tie them with the strings
Rub both on your sweater for a few minutes
What happens?
Why do you think it happens?
What happens to the balloon closest to your sweater?

After you have rubbed the balloons on your sweater, they are both negatively laden with electrons they withdrew from your sweater. Because the sweater has given off the electrons it is now positively laden, this is why the balloon closest to your sweater sticks to your sweater while the two balloons drift far apart. So, what does that tell you about two objects that are negative or positively laden?

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

Examples Of Science Fair Projects – Air Pressure And Air Weight

Examples Of Science Fair Projects – Air Pressure And Air Weight

Get more Science Fair Projects at Easy Science Fair Projects

This science project is one of our examples of science fair projects where you actually proof two related characteristics of air. You will prove that air has weight and that, because of the weight, air pressure is strong enough to bend a can. We are going to use the principle that as air heats up; it has a greater volume and if it is in a container some of the air will escape from the container. Then by screwing a top on the container we are going to prevent the air from going back in when the container cools down.

CAUTION: This example science fair project must be done with adult supervision as heat is used.

What you will need for this experiment:

Large container
A can with a screw top (you get cans of olive oil that will be the ideal can)
Water
Stove
Oven mitts
Ice
Dish cloth
A scale
Note book
Pen
Camera

How to do this science experiment:

For your display, it is a good idea to take a photo of the can in its original state.
Fill the large container with water and ice and put it to one side until you need it.
With a finely calibrated scale, weigh the can with the screw top on.
Make a note of this weight.
Remove the screw top.
Put the can on the burner on the stove.
Heat the can until it is very hot.
Using the oven mitts, remove the can from the stove and, working quickly, screw the top on the can and place it in the cold water.
Observe what happens, write it down and take a photo.
When the can has cooled down, wipe it dry and weigh it.
Make a note of the weight and take a photo.
What has happened?
Why do you think it happened, remember we said in the beginning that we are going to prove two things?

What happens is that the air pressure bends the can. Why can we say that? What did we do to remove air from the can so that the air pressure on the outside is more than in the inside?

The other thing that happens is that the can now weighs less. Why is that? Think of what we have done with the air in the can.

This is just one of our many examples of science fair projects. For more fun and easy examples of science fair projects visit our site Easy Science Fair Projects.
