Microscopes

The word Microscope it given to the tool used to view object that are too small to be seen with the naked eye.

        During the 1st century AD, glass had been invented and the Romans were looking through the glass. They experimented with different shapes of clear glass and one of their samples was thick in the middle and thin on the edges. They discovered that if you held one of these pieces of glass over an object, the object would look larger. Before microscopes as we know where invented, what was considered as a microscope was just really a Magnifying Lens, early biologist used them to study tiny insects such as Fleas, thus the viewer was called a Flea Lens.

         Two Dutch spectacle makers in the 1590’s (Zaccharias Janssen and his father Hans) experimented with lenses and realised that if several lenses were put into a tube and the object is viewed it appears larger than viewed by any magnifying lens, this was the invention of the Compound Microscope.

        Anthony Leeuwenhoek of Holland who worked in a dry goods store had a great interest in lens and began making some of his own. By grinding and polishing, he was able to make small lenses with great curves. His rounder lenses produced greater magnification. Anthony Leeuwenhoek’s new microscope got him interested in science and with his new improved microscope was able to see things that no man had ever seen before.  He saw bacteria, yeast, blood cells and many tiny animals swimming about in a drop of water.

There are two types of modern Microscopes the Compound Light Microscope and the Electron Microscope.

The light Microscopes that modern sciences use today are a lot more powerful, sophisticated and widely available at low cost. The term light refers to the method by which light transmits the image to your eye. Compound deals with the microscope having more than one lens. Microscope is the combination of two words; "micro" meaning small and "scope" meaning view. Simple light microscopes of ...

The spelling, grammar and punctuation are fine. The technical terms could be put into a glossary and defined - this would be that 'one step further' as it would further show the student's understanding of the topic. The student follows the normal convention in their layout of the work as it is typical (and sensible) to lay it out with headings and diagrams. This helps the examiner clearly identify the part of the question that the student is addressing.

The level of analysis in this piece of work is average. It covers the fundamentals of the topic well but lacks depth of knowledge. This would highlight the student's piece of work and further illustrate their understanding of the topic. Also, depending on what the question is, the piece of work lacks an conclusion to sum up the piece of work and the student's findings. This can be vital, but again, depends on the question set. Yet, the response is clearly and logically set out and the use of diagrams helps illustrate what the student is referring to. It is important to remember to source the diagrams used in the work as well.

As I don't know what the question set is, it is hard to judge how well the student has answered the question. Ultimately I believe that the student has addressed the background knowledge and the fundamental understanding of the topic well. However, I feel there is a lack of detailed knowledge to the functions of the microscope. Obviously this all depends on the requirements of the board, yet whatever the requirements of the board, going that 'one step further' really differentiates an A (A*) grade piece of work from the lower grades. The presence of a bibliography is commendable as the student has clearly acknowledged their sources which prevents any accusations of plagiarism happening.
