As you know, children have an endless supply of curiosity. Their desire to learn the secrets of the surrounding world extends from space expanses to the smallest details, which can not be considered with the naked eye. Therefore sooner or later many parents have a question: "How much does a microscope for a schoolboy cost and how to choose it?". It is about which microscope to choose a schoolboy, and we will understand our article.
School microscope: features of choice
Starting with the choice of a microscope for a schoolboy, parents will first of all decide what this uneasy device will be used for. It is from this that the class of the device and, consequently, its cost will depend. If it is a question of the child's first acquaintance with the microcosm, then it is possible to choose the so-called children's microscopes, which have a minimum of possibilities, but also stand a little. If the microscope is necessary for training, then it is worth buying a school (educational) microscope. School microscopes can give an increase up to 650x. The most popular among school microscopes are the following:
- stereomicroscopes;
- biological monocular microscopes.
It is precisely between these two types of microscopes that a choice is usually made when buying a microscope for a schoolboy. What are they different? The difference between these devices, primarily in the object of study. Stereomicroscopes are designed to study much larger objects, such as insects. They give a smaller increase, but they do not so burden vision, because the child looks at them with two eyes at once. In addition, binocular stereomicroscopes make it possible to obtain a three-dimensional image. Biological monocular microscopes have a greater magnification, and therefore allow to consider smaller objects: animal hair, plant cells, thin sections of various tissues. But in this case, monocular microscopes give a greater load of vision and are more difficult to operate, because the schoolchild himself will have to prepare samples for studying: making slices, staining and drying drugs, etc.
When choosing a model of a school microscope, it is not superfluous to pay attention to the presence of illumination in it. Practically all modern microscopes are equipped with built-in lighting, which allows to better examine the object of study.
School digital microscope
Another type of school microscopes are digital microscopes. It is quite an expensive device, but it also has a lot of possibilities. First of all, a school digital microscope allows you to display an image on a computer monitor. Thus, the child not only can get an enlarged image of the object that interested him with the help of a microscope, but also save the resulting picture for further study or editing. This allows you to track changes that occur with the object of observation in the dynamics. Secondly, the digital microscope is mobile - it can be easily removed from the stand, moved from place to place, thus obtaining an enlarged image of any object in the room. On the one hand, this is
How much does a microscope cost for a student?
Depending on the model chosen, the purchase of a school microscope will cost the parents in the amount of 40 to 500 conventional units.
Of course, the microscope is not included in the list of compulsory purchases for the school , along with notebooks, pencil cases and a backpack, but its acquisition will definitely help the child in its all-round development.
