Did You Know?
|
Did you know that the static electricity generated on your body
when you drag your feet across the carpet can be in excess of 10,000 volts? Fortunately,
the amperage is so low that it’s harmless!
Edmund Scientific's has a Static Electricity Bulb
that actually lights up from the static electricity in your body. In a dark room
this cool little bulb really glows!
Static electricity generally occurs when certain materials are rubbed together.
When these materials are rubbed together, electrons are pulled from the surface
of one material to the other. The shock occurs when the material that has been charged
with negative electrons comes into contact with a positively charged conductor.
Physicists believed that static electricity was different than other electrical
charges until 1832, when Michael Faraday published the results of his research on
the identity of electricities.

Welcome to the Free Science Fair Projects Network! |
The Free Science Fair Projects Network brings you the best resources on the internet
for your science fair projects, without popups and banners. Select your school
grade and take a look at the examples of real completed projects. If you already
have an idea and just need some information to complete your science fair project,
use the resources broken down by topic for the best free information on the internet.
NEED SUPPLIES? We recommend two great places that have been
around for years.
ScienceKit.com has tons of supplies for your science fair projects.
Edmund Scientifics
has been my personal favorite for everything related to science, since I can remember.

Help The Free Science Fair Projects Network Help You! |
 With
school beginning to get in full swing for the new school year, many of you will be participating in a science fair project this year.
Help us keep the Free Science Fair Projects Network up to date. From your
research this year, you have probably found one or two free "gems" along the way
that would really help someone else with their science project. If everyone
contributes what they know, we can gather the best of these free resources into
one place so that we can all help each other.
Visit our Contact Us page to report a great link that
has free science fair projects. If you used a website for research in your
science project that has good solid resources in biology, chemistry, physics, etc.,
send us a link. On behalf of everyone that has taken advantage of the resources
available at the Free Science Fair Projects Network, we offer a sincere "thank you"
in advance for your help this year!

Recent Questions We've Received About Science Fair Projects |
From Gail:
I would like to do a science fair project testing shock absorbency and playground materials. Any suggestions on how to measure this?
I believe in order to get an accurate measurement of the shock absorbency for different
playground materials, you will need either an Acceleration Sensor or a Force Sensor.
Of course, you will need to drop an object, such as some type of weight, onto the
playground material and either mount the sensor on the object being dropped or onto
the material being tested so the sensor is in a position to measure the force.
A less accurate method that would keep your costs down, would be to drop a ball
that will bounce (rubber ball, super ball, etc.) from a platform. Use whatever controls
are necessary to make sure it drops the same way each time and count the number
of times the ball bounces. You could also use a sharply angled ramp to launch the
ball and measure the distance the ball travels until it stops bouncing and comes
to rest. More absorbency would cause the ball to bounce or travel less.
Obviously,
accuracy would not be perfect with these two methods, but the results may be reliable
enough if you can keep the variables as tightly controlled as possible. You might
even use both methods to gather more data and have better accuracy!
From Treva in Carmel, IN:
I need to find a project to prove the existence of air.
A couple of ideas immediately come to mind:
- Blow up a balloon. Using either your own lung power or a tire pump, inflate a balloon. As the balloon inflates you can easily and verifiably see that the air going into the balloon has mass.
- Hold your breath! Ask a friend to hold their breath as long as they can. It won't be long before they are forced to breath again. The need to fill their lungs demonstrates that air has properties which are necessary for our biological processes (our life) to function.
- Put a candle out. This should only be attempted with the help of an adult. Light a small candle and set it firmly on a table. Once it is burning, place a much larger clear glass jar over it upside down so that no air can get in. The candle will soon be extinguished. This demonstrates that the properties of air can be changed, in this case the oxygen is consumed from the air and the flame no longer has one of the elements it needs to continue burning.
I don't know if this answers your question, but hopefully it will help you create a successful science fair project!
From Abraham in El Paso, TX:
Do plants grow faster with sunlight or artificial light?
That would be a great topic for a project. Obviously, artificial light is able to
be on 24/7 whereas natural light is restricted to daytime. The real question becomes
which grows plants faster when all other factors are constant.
I don't know the answer to this question, but this should be your project. Keep
all other factors the same: watering, nutrients, exposure to moving air, temperature,
location of the plants when they are not in the light, etc. They should probably
be kept in complete darkness in the same location, side by side when not in the
light.
I would use 4 test groups of 12 plants each as follows:
- Group 1: Artificial Light 5-6 hours per day
- Group 2: Natural Light 5-6 hours per day
- Group 3: Artificial Light 8-12 hours per day
- Group 4: Natural Light 8-12 hours per day
This should give you some excellent data. The reason for the two lengths of time
is because in the morning and evening, sunlight penetrates the atmosphere at an angle
which will probably be a factor in their growth rate.
I hope this gets you started in the right direction. My bet is on the artificial
lights!
From Eric in New Jersey:
My son is doing a science
project comparing the magneticity of various metals. But we can't find the various
metals! We need a few different pieces that are of uniform size and weight. Any
ideas?
ScienceKit.com
has the Specific Gravity Metal Specimen Set (same sizes, but different
masses). You might also try the Equal Mass Density Cubes
(different sizes, but same mass).
Actually, if you can afford it, it would be interesting to do the project from both
angles, one batch with the same size, and one batch with the same mass!
Hope this helps, and best wishes on your project!
