A Close-Up Look At Microscopes
by Logan Pallas
The microscope is an important educational tool used in
scientific research and education. It is used to produce a
larger image of an object for projects ranging from medical
discoveries to important educational training in schools across
the nation. Microscopes use technology to allow humans to view
objects as they could never be seen with the naked eye alone.
A conventional microscope was first developed during the last
part of the 16th century, which lead the world of science
toward a prospering future in the world of medicine and
biology. In its earliest years, the microscope was primarily
used as a recreational device and was found mainly in wealthier
homes. It wasn't long, however, before technology and research
began to blend for a new discovery relating to blood
circulation. In addition, advancements in the study of bacteria
and diseases were among the discoveries that followed.
The majority of microscopes are called light microscopes, which
uses a series of high powered magnifying lenses in order to bend
light rays. Studies continued through the seventeenth and
eighteenth centuries while, at the end of the nineteenth
century, an even bigger development occurred. With the
realization that electrons could be used as a light source in
microscopes, scientists were provided with a never before seen
resolution. The first electron microscope was unveiled
approximately 75 years ago, which allowed for even smaller
things to be researched and viewed. Among the advancements,
atoms were finally visible for the first time and viruses could
finally be identified with the powerful magnification and
resolution of the electron microscope.
A microscope is an important tool and should be treated
carefully. Proper care should be exercised when handling, or
transporting, a microscope in order to avoid damage to the
unit. Always carry the microscope with both hands and in the
upright position. If you have a special tote or a box, either
will work fine for transportation. When the microscope is in
use, always make sure that it is placed on a flat surface and
one that is not shaky. A sturdy table is the best placement for
a microscope, but avoid placing it close to the edge where it
could fall off to the side. After each use, follow the
manufacturer's instructions in proper cleanup of the unit, as
well as any slides. If you do not plan to view the slides
contents again, they should be cleaned in order to avoid
interaction with future items that are placed on the slide for
viewing.
While much emphasis is placed on scientific research and the
technical aspects of microscopes, it's important to remember
that children can also benefit from the tool's educational
teachings. When you're a child, it's fun to collect a sample of
anything and check it out under a microscope. Of course,
microscopes begin as toys for smaller children and advance to
larger, and more realistic models, as the child ages and is
better able to understand the importance of the tool. If a
child learns to be familiar with a microscope at a young age,
he/she will be much more prepared for biology classes and the
various parts and styles of microscopes.

Let Your Kids See The World From A Different Perspective, Give Them A Microscope by Abbie Frank
There are many things you provide to your children especially at birthdays and holidays. The problem however is that much of what we give to our kids are the electronic, site and watch or listen types of gifts. These do precious little to encourage their sense of understanding, wonderment or interest in the world around them.
All kids have an interest in the outside world and latent creativity. What makes things work and why are two of the strongest interests in many kids. The trick for parents is to bring out these natural interests through activities that encourage exploration and development.
If your interested in helping your child to develop a well rounded interest in life [and who isn't] it's important to expose them to new activities. We're not talking about turning on the Travel Channel or Discovery on the television. Kids learn by hands on activities like having a microscope.
Here are a few examples.
Want to teach your child about the environment? Get them a microscope. Collect some trash like a banana peel and a water bottle. Leave both outside for a few weeks then go exploring. Use the microscope to see how the banana peel has decomposed at a cellular level and will return back into the environment. Now look at the plastic bottle.
How about checking out something as simple as tree leaves? Using leaves as a lead in, it would make a perfect time to explain the role trees play in keeping our air clean by using carbon dioxide and creating oxygen.
Use a microscope to look at water from different sources. From the kitchen sink, there's far fewer "debris" than the gutter run off from a spring rain. This would be a perfect time to explain how thinking before pouring anything down the drain can help the environment.
There are thousands of things that you can use a microscope for to encourage your childs natural curiosity and get them away from the electronic playground we're provided for them. A microscope can get them outside, exploring their world, enjoying the air and wonderment that is our planet. Just get them started and the interest will take off.
When selecting a microscope for child use, consider one that supports the ability to take pictures of the results. This will enable you to create photos of the things your kids found fascinating. The pictures make great decorations on a bedroom wall which in turn may generate even more interest in learning more about a subject.
Open a real world for your childrens enjoyment and exploration. Get them a microscope.
