Wants to interview on science project
March 18, 2012
Dear Mr. Ron Kurtus:
I am writing to ask permission to interview you by email for my science project. I would like to send you four or five questions concerning your work and my science fair project. I am a fifth grade student testing whether hair color affects the amount of static electricity produced. I understand you are busy and may not have time, but any help is appreciated.
Macie - USA (22516)
Static electricity and hair color is a good experiment. But the big factor is not so much color but the thickness of the strands of hair and how oily the hair is.
Redheads usually have very thin, dry strands of hair, which should respond well to static charges. People with black, straight hair usually have thicker strands of hair. Also, some may have more oily hair that may not respond well to static electricity.
Feel free to ask questions on your project, and I'll try to answer them.
Send me more experiments for static electricity?
March 9, 2012
could you send me some more of your experiments for static electricity?
zachery - USA (22495)
Sorry, but that is all we have available right now.
We'll be adding more experiments in the near future.
I want an experiment on electroscope
February 19, 2012
i want experiment on electroscope
apurv - India (22432)
An electroscope is used to detect static electricity. You can make or purchase an electroscope to do experiments in detecting and measuring static electricity.
See: Detection of Static Electricity for more information.
See: Simple Electroscope for how to make one.
What is the reason for doing this experiment?
November 20, 2011
what is the reason for doing this experiment
chanda - USA (22185)
Most static electricity experiments are simply demonstrations of the effects of the force. You can also try to vary things to see which method works the best. The most difficult thing is to actually measure the forces involved.
How to light a bulb with static electricity
August 29, 2011
How to light a bulb and enable the static electricity to make some devices to charge if any please do mail to my id i want to know the exact procedure to do the things with static electricity
- India (21929)
Using a high power static electricity generator, such as a Van de Graaff generator, you can light fluorescent bulbs at a distance.
See Generating Static Electricity as a source.
Also, go though our lessons and experiments.
Want an idea for a science experiment
August 27, 2011
any science experiment and give ideas
Bharani - India (21927)
First of all, you have to pick an area of interest to you for an experiment.
You can try to demonstrate some phenomenon, such as showing how static electricity can affect things.
Or you can see what would happen if you changes something. Supposed you tried to bend water with a statically charged comb. Would things be different for different types of combs? What about hot water versus cold water?
Go through our lessons on Experiments for more ideas.
Wants help in science project
July 13, 2011
Sir i want to contact you i want your help in making a science model please help me
- India (21806)
Pick an area in science that interests you and then decide what you want to do. A good place to start is by looking at Science Experiments.
Once you have an idea of what you want to do, feel free to contact me.
We used a ball and a hoop for expansion
June 2, 2011
we used a ball and a hoop for expansion
- Australia (21668)
What did you do? Did you heat the ball to see if it expanded and couldn't get through the hoop?
Experiment on effect of magnetism
May 4, 2011
My daughter has conducted a 4th grade science project about magnetism and how cardboard, plastic and glass affects its force when placed between magnets. We found that when we kept each of the materials very thin, the magnetism was not affected. However, when we changed the thickness equally, the cardboard affected the magnetism first, followed by the glass, while the thicker plastic hardly affected the magnetism. While we can prove the results via the experiment, we cant explain it. Do you have any explanation we can offer as to why the cardboard affected the magnetism first? Again, to keep the experiment controlled, we kept the same thickness in both sets of materials. Ive searched the net and have not come up with any answers. Im going to say that it has to do with the density of molecules in each of the materials? Any explanation would be welcome.
- USA (21549)
That sounds like a good experiment.
The approximate densities of the materials in kg per cubic m are:
Cardboard = 700
Glass = 260
Plastic = 3
So, my guess is that the density of the molecules is a big factor. Also, cardboard is made of compressed fibers, glass is somewhat of a crystalline material, while plastic usually consists of long molecules. That may be a factor too, but I think density is the greatest factor in the reduction of the magnetic effect.
Experiment with wool scarf
March 8, 2011
what is the name of the website where u can use a wool scarf punch in holes with a hole puncher out of paper and use four balloons and that has to be the same size. but yeah will u try it out? i think its pretty interesting.
crystal - USA (21307)
I'm not sure what the experiment you describe is supposed to do. What do the four balloons do? Do they separate after being rubbed with the wool scarf?
Experiment to show static electricity
March 3, 2011
What is the best experiment to show static electricity ?
Can static electricity be dangerous ?
Joanna - UK (21287)
Rubbing a balloon on a sweater to get it charged with static electricity is a good experiment. You can put the balloon near someone's head to cause the hair to stand on end, you can pick up small prices of paper with the balloon, and you can stick the balloon to the wall.
See Experiments with Static Electricity for more.
Static electricity can cause explosions. See Controlling Static Electricity.
I want an intresting experiment
January 1, 2011
i want a intresting experiment in science.
uzumaki - India (20941)
You want to pick something that is interesting to you. Is there something about the states of matter that arouses your curiosity? For example, how much does the volume of water change when it turns to ice? Does it increase or decrease?
that might be a good experiment.
How can I make working model for Geothermal Energy?
October 12, 2010
How can I make working model for Geothermal Energy, Nuclear Energy and Hydel Power?
Anubhav - India (20525)
You could use a pot of boiling water to simulate the geothermal effect underground and then have that heated water rise up a tube to heat a toy building.
Nuclear energy is not practical as a working model.
Hydel Power or Mico-hydro power can be demonstrated with a water container and a vane that turns a small generator.
How can I make paper stick to me?
September 19, 2010
how can i make plain stock paper being blown around me stick to me (is there a "tibelectric series" potential)?
brian - USA (20407)
Either you or the paper must have a static electricity charge. It is preferred that both of you are charged with opposite charges.
Often paper that is blown around will pick up and electrical charge. However, it may not be sufficient to stick to you. In newspaper companies, they have rolls of paper that are moving rapidly. That paper often creates enough charge to stick to things and even cause sparks.
Wants some project ideas
June 28, 2010
any project ideas in the field of electronic and communication?
joseph - India (19984)
What type of project are you considering? Is this for a science fair? Is it for students to study?
The definition of the objective of a project should be very clear. You need to state the audience or reason for the project, before you can state an idea for one.
