This sounds like a question of the Stone Age. All grade school students have probably done an experiment relating to this in their science class or in their backyard. The moral of the story is to keep the matchsticks away from misguided children.
Most microscopes that you see in a typical laboratory environment are compound microscopes. They are designed with objectives on a rotating nosepiece mounted above the stage, and the light source and condenser below the stage. They are most commonly used for viewing samples that have been fixed to a flat slide.
There are two basic types of dissecting microscopes. One style allows you to read at two fixed magnification settings, such as 10X and 20X or 10X and 40X. The other style has the capability to

World and outer world fascination has always seemed to hold man in its power. Human beings seem to have a capability to want to know more about all the planets that exist within our solar system and in worlds beyond. Perhaps our fascination of life beyond earth is the key that fuels all types of inventions that permit us to hope that we are not alone.

The cost on the energy is killing us there is immense cost on management of our automobiles and man! It's so difficult to pay these huge amounts of bills. And as we know the fossil fuel also becomes scare In the need to develop substitute forms of energy it is getting more and more difficult for the people.
You often hear the term brix and brix refractometer when testing samples for sugar content. Just what is a refractometer? A refractometer is an instrument that measures the refraction of light through a substance. The refractive index becomes higher in a substance of higher concentration.
Remember back to your school days when you first saw amoeba swimming around in pond water? You thrilled to seeing the microscopic organisms moving around, bumping into each other. Now you want to share that memory with your children or grandchildren as they grow. But you don't want to spend their college money on a new high-priced microscope, so what can you do? No problem - you can now find many microscopes that are either used or demo models at a much more reasonable price. But first you need to determine what type of a used microscope you want: compound or stereo/dissecting.
Various electronic kits are available, and the potential benefits go beyond the finished product. For a start, it's a hands-on opportunity to become familiar with some terminology. By high school, science classes often include an introduction to electronics concepts, including circuit diagrams, resistors, and diodes.
So you have a beautiful brand new science kit, such as a chemistry set, and you want to set up a truly scientific experiment, something really professional, something tightly organized and keenly observed. Sounds like a great idea so far! So where do you begin? The first step, perhaps the most important step, is a well-thought-out hypothesis. This article provides instructions for how to make a great hypothesis.
Kids electronic kits are a great way to learn how different energies, from solar to hydrogen, work together. These energies are used to develop new technologies and better ways of doing things. Using electronics kits to harness these forces is not only a great way to learn but can also be a lot of fun.
