How to Buy the Right Kids Student Microscopes
Curious kids love to explore and investigate. From an early age, a hand-held Magnifying Glass offers a new perspective to young scientists and explorers. Common objects are fascinating when seen in detail, and it helps kids understand the world around them.
A Student Microscope allows kids to take their explorations and their understanding to a new level. Having a basic microscope at home supports home learners, budding scientists, and in-depth science projects. It is possible to buy microscopes that are robust enough for daily use yet have powerful magnification. Many scientific supply companies and educational stores sell a range of Prepared Slides as well.
Certain key features are important when you buy microscopes. This is especially true with a student microscope, when ease of use is important for avoiding frustration. There are two levels of student Microscope Power, based on the level of magnification.
1. Low power microscopes are useful for looking at larger objects like rocks, flowers, coins, and insects. Typical magnifications range from 10X up to 80X. There are usually two eyepieces to provide a three-dimensional view. The most common useful magnifications are 20-30X.
2. If you opt to buy microscopes with High Power, the range might go up to 1000X magnification, making it possible to see single-cell organisms in pond water, hairs, and cells. A less-expensive student microscope will have one eyepiece, which can be easier for younger kids to use. However, binocular versions, with two eyepieces, offer superior viewing for older kids.
Other features to consider include the following:
1. Power source: Many models are cordless and rechargeable, making them easier to take out on field trips.
2. Construction: Make sure the student microscope has a metal frame, optical glass lenses, and built-in Light Source. Opting for a cheaper version, usually plastic, will be a waste of money due to poorer resolution and a flimsier frame. Lenses marked DIN meet industry standards, so they will be high quality and fully replaceable. Look for lenses that are achromatic, meaning they have built-in color correction and less distortion. These features give more accurate viewing. A wide-field eyepiece is easier for children to use.
3. Light source: Some light bulbs produce heat, limiting a microscope’s use with live specimens. Generally, fluorescent and LED bulbs are cooler, while tungsten and halogen heat up more. Before you buy microscopes, make sure they offer an easy way to reorder more light bulbs, as this part will need more replacing.
4. Controls: Depending on a child’s age, student microscopes have user-friendly features. More robust and simpler models work for younger kids, while older kids appreciate more choices in magnification and control knobs. Make sure the microscope has both coarse and fine focus options. Some models have a Mechanical Stage so that slides can be moved smoothly for positioning under the lens.
Parents should think about their children’s interests before they buy microscopes. Different microscopes and magnifications suit different subjects. An insect enthusiast or coin collector only requires 10-20X magnification and a top-mounted light, while a junior microbiologist needs 400-1000X magnification and a bottom-mounted light source.
