Science doesn't have to be
complicated, expensive or use specialized laboratory equipment.
There are great science projects that can be performed using common
Whether you are a parent or a student trying
to find an idea for a science project, a teacher looking for ideas
for the classroom, or a science enthusiast who enjoys the delight of
experimentation, you'll find what you're looking for in this book.
Children love making gifts for their parents and other adults who
are important to them. But what can they make that will delight the
person they are giving the gift to?
Here's how you can quickly and easily get lots of simple, high quality
gift ideas that you children can make. Guaranteed to be fun the
children making the gift, and a delight for the person receiving it.
What is the
difference between the Geographic north pole and the Magnetic north
The geographic north pole is the top of the planet. Its position
does not change. The north magnetic pole is the point where all of
the magnetic lines of the field flow directly into the earth.
Magnetic North is constantly in motion, currently moving
approximately 26 miles (40 Km) per year. Right now the Earth’s
magnetic north pole is in northern Canada. If the north magnetic
pole continues on its present course and speed, it will be in
northern Siberia by the year 2050. The magnetic poles have even
reversed themselves, with the north magnetic pole being in the south
and the south magnetic pole being in the north.
While the earth’s magnetic field
allows compasses on earth to work, it has a much more vital
function. It acts as a shield, protecting the earth from solar
particles emissions from the sun. These solar particles are
constantly generated, streaming out from the sun in all directions.
During solar flares, huge amounts of these particles are generated,
creating vast clouds of highly energetic particles that race toward
earth at speeds up to 1000km per second.
The clouds of particles approach
Earth and are deflected away by Earths magnetic field. If these rays
were not deflected, life on earth (if it existed) would be radically
The rays are deflected away from the
earth. Once the rays have passed by the earth, some of them move
back along the lines of magnetic force to the north and south poles.
When the cosmic rays strike the upper regions of the atmosphere, the
Aurora Borealis (Northern Lights) or Aurora Australis (Southern
Lights) are formed. The planets that have magnetic fields around
them have their own form of the Aurora Borealis.

According to the latest work at Nasa,
currently, Mars does not have a global magnetic field. But it
did have one early in its life, similar to that of Earth.
Even though it doesn't have a global magnetic field today, Mars does have very strong crustal magnetic fields, more than 30 times stronger than those of Earth.
