We had a mix of experiences whereas reviewing the National Geographic Ultimate Dual. Stereo microscopes will be tough to make use of, so it was a problem for younger novices to fathom. However, what began off as fairly a irritating expertise went on to present a wealth of pleasure, journey and discovery. This microscope package has the correct steadiness of schooling and enjoyable to offer children with participating duties that they’ll perform independently.
The identify of this microscope, Ultimate Dual, describes the 2 completely different LED placements, higher and decrease. But it may be a nod to its multitude of paired features: for strong and clear objects, lab and out of doors use, dwelling and non-living specimens, or due to the 2 separate pictures wanted for stereo 3D viewing.
The actions potential with the National Geographic Ultimate Dual stereo microscope package are quite a few and assorted and can give youngsters a superb introduction to the world of microscopy.
Kids who’re a bit older would possibly profit from probably the greatest microscopes for college students, whereas youthful youngsters who’re simply getting taken with science will love the perfect microscopes for teenagers.
National Geographic Ultimate Dual Stereo Microscope evaluate
National Geographic Ultimate Dual Stereo Microscope: Design
- Attractive as a present
- Scientific equipment package
- Ideal for youthful youngsters
The National Geographic Ultimate Dual Stereo Microscope has been designed as a whole, versatile starter package for kids. By layering two separate pictures, one from every of the binocular tubes, its stereo design creates a three-dimensional picture.
The decrease LED permits mild to be shone by way of specimens, which is right for translucent or very skinny objects, particularly slides of cells and tissues. The higher LED shines onto strong objects from above and permits their form and texture to be visualized. With a number of equipment, we discovered that this design has hit the correct steadiness between being enjoyable and academic, having virtually the whole lot wanted to offer hours of 3D exploring.
Designed as a present, the outer packaging is engaging. The field is shiny but textured, coupled with some engaging pictures that give this product shelf attraction and make you need to delve inside. Children loved discovering a number of packages inside: this created pleasure and added to the unwrapping pleasure. Adults loved the whole package deal idea in order that no additional parts have been obligatory. But it was irritating that the microscope wanted batteries, which weren’t equipped. It would have been helpful if this data was printed on the field — we might have been extra ready. There is nothing worse than a present that can not be instantly loved!
We have been happy that the equipment included have been convincingly “scientific.” Having a pipette and tweezers to switch solids and liquids made the entire expertise extra lifelike. The petri dish was additionally sensible for holding pond water, relatively than having to arrange slides. The equipment enabled instantaneous gratification within the type of ready slides and the rock pattern. Yet each prompted additional investigation by way of scientific enquiry.
Blank slides have been included, for the preparation of youngsters’s personal slides. Seeing the shape and textures of the rock stimulated the youngsters’ imaginations they usually have been quickly on the hunt for feathers, shells, moss, seeds and flowers to place beneath scrutiny. Although we have been unsuccessful in hatching any brine shrimp, we might see the profit in getting children to realize expertise in following a technique and patiently awaiting the outcomes.

Another good contact was the academic booklet. Not solely did it comprise details about learn how to use the microscope, there was additionally a bit on the historical past of the microscope and ideas for experiments that could possibly be carried out utilizing it. Sadly, the booklet contained a number of errors (we recognized three with only a fast scan). The most blatant was in a duplicated illustration title — three completely different pictures requested, “What are fossils?” however this was related to solely one in all them.
Designed with youthful youngsters in thoughts, there have been quite a few options that made the Ultimate Dual a safer product. Powered completely by batteries, children wouldn’t have to plug it into the mains electrical energy. Additionally, though nonetheless fabricated from glass, we seen that the corners of the slides had been rounded off, minimizing the possibility of cuts. The microscope was additionally mild, so it could possibly be carried simply.
Unfortunately, we recognized one hazard that does want addressing. The glass cowl above the decrease LED shouldn’t be mounted in place. When turning the microscope the wrong way up to insert the batteries, the glass fell out. This might have damaged and been a chopping hazard. It additionally uncovered the bulb beneath. Moreover, the eyepiece lenses fell out as nicely!
National Geographic Ultimate Dual Stereo Microscope: Performance
- Great for 3D viewing, as soon as binoculars are arrange appropriately
- Good for strong objects
- Low magnification shouldn’t be ultimate for cell microscopy
When judging the efficiency of the National Geographic Ultimate Dual stereo microscope you will need to acknowledge that, though we discovered the efficiency poor when observing cells, this microscope was an excellent instrument for magnifying strong objects and seeing their three-dimensional construction and floor textures.
If your main use for a microscope is to watch cells, the Ultimate Dual might be not the correct selection for you. There are extra strong, higher-quality microscopes accessible with a a lot larger magnification. The highest magnification is achieved when utilizing the 25X eyepieces. The general magnification turns into 50X, due to the 2X goal lens. However, that is the equal of the minimal magnification on different, equally priced compound microscopes. Cells have to be significantly enlarged to watch the buildings inside them. Ergo, the Ultimate Dual falls quick on this space.

Fortunately, the viewing of strong objects in 3D is the place the National Geographic Ultimate Dual shines. Although tough to arrange initially, as soon as the binocular distance is appropriately arrange for the viewer, specimens will be swapped and interchanged with ease.
Objects noticed in stereo have a surreal high quality. The picture pops out in the direction of you and may give the impact of floating as you progress your head. This can really feel a bit unusual, however it’s also actually thrilling, particularly with bigger objects like complete bugs, shells and rocks. Although fiddly, it was value persevering with because the thrilling 3D imagery was new to the kids — even those that had used a microscope earlier than.

An additional advantage of the Ultimate Dual is that the highest LED illuminates objects from above, bouncing mild from the floor up by way of the phototubes. This is what makes observing strong objects potential. As the sunshine displays, coloration and texture are retained. Beautiful patterns have been seen on flowers, butterfly wings and feathers. The Ultimate Dual was used on this strategy to dissect flowers and look at water from the pond.
Pond water was pipetted into the petri dish and inspected with the highest mild. Some small creatures have been enlarged to 50X magnification. However, 25X magnification was extra helpful right here so {that a} wider area of view might seize extra exercise. Flowers have been dissected with tweezers, to take away the stamen and petals and in some circumstances expose the seeds throughout the ovaries. Although small, all of the equipment carried out nicely throughout our investigations.
In abstract, the National Geographic Ultimate Dual Stereo Microscope carried out brilliantly when viewing strong specimens in 3D, however poorly when magnifying most cells. However, the youthful youngsters who would take pleasure in utilizing this instrument to enlarge objects of curiosity round their home and backyard in all probability haven’t begun studying in regards to the construction of cells but anyway. So in actuality, this will not be an enormous drawback in any respect.
National Geographic Ultimate Dual Stereo Microscope: Functionality
Image 1 of 2
- Capable of viewing strong objects in 3D
- Deep viewing platform for bigger objects
- Choice of eyepiece lenses
The National Geographic Ultimate Dual had 4 completely different features that wanted to be arrange appropriately earlier than being rewarded with a picture. But as soon as defined and demonstrated, youngsters might confidently and independently change between specimens and let their imaginations and marvel take over.
Our youngest participant was 7 years outdated. After following directions a couple of occasions, she turned impressively competent in adjusting her binoculars, deciding on the proper LED, shifting her specimen into view and focusing.
The most intricate maneuver was to position the binocular eyepieces on the optimum distance in order that the 2 separate pictures turned layered on high of each other, which is crucial for stereo 3D viewing. This measurement is completely different for every observer. Therefore, binocular placement can’t be arrange by an grownup because the interpupillary distance won’t match the kid’s. We discovered that the perfect method for this was to get the kid to look by way of the eyepieces, and not using a specimen, with the decrease LED on. Ask them to carry the phototubes collectively till they see only one circle, and the machine is then prepared for use.

Unfortunately, this interfered with the instructing course of considerably, as shared viewing required binocular adjustment for each new viewer. We compromised by leaving the binoculars set to the kid’s interpupillary distance and viewing by way of one eyepiece solely. We weren’t seeing the 3D picture however have been in a position to be a part of within the pleasure.
One perform that we significantly loved was having the stage in a everlasting place with the eyepieces shifting up and down whereas focusing. Keeping the specimens nonetheless enabled us to pick out moderately giant objects. The mounted stage was ultimate for supporting an enormous moth with the intention to enlarge the tip of its wing with out damaging it.

The stage-to-objective lens distance was additionally comparatively giant, giving us sufficient room to watch taller objects. We had resin-mounted invertebrates — crabs and a scorpion — in addition to shells and rocks. We additionally had sufficient room to position our fingers beneath the microscope, to scrutinize all of the nooks and crannies in our pores and skin and nails.
The Ultimate Dual, as its identify suggests, advantages from having two completely different mild sources. The higher and decrease LEDs will be modified immediately, on the flick of a change. Children did this with ease and rapidly discovered what was obligatory for every state of affairs: higher LED for strong objects, and decrease LED for translucent sections of tissues and organisms on slides. Sadly, the brightness on the LEDs was not adjustable, which means some samples have been too shiny, and others too darkish.
To conclude, though there have been quite a few features to get proper, the kids we launched to it have been enthusiastic, fast to be taught and proud to point out how succesful and impartial they have been. We would suggest the National Geographic Ultimate Dual stereo microscope as a present for youthful members of the family or pals, so long as you could have time to assist get them began on their microscopic journey.

How we check
During a neighborhood science afternoon, children got free rein with an abundance of 3D objects to view, together with classic invertebrates, resin-mounted invertebrates, flowers, seeds, ready slides, shells, moss, cash and rocks. Children have been guided to make use of the petri dish and tweezers to deal with their specimens and have been inspired to arrange some easy slides of their very own. Later, youngsters explored the gardens to seek out different fascinating dwelling and non-living issues to look at.
In preparation for the science afternoon, we tried to boost some brine shrimp from the equipped eggs, utilizing the hatchery. Sadly we have been unsuccessful, and regardless of our greatest efforts, the eggs did not hatch. Fortunately, due to its portability, we have been in a position to display the live-viewing functionality of the National Geographic Ultimate Dual by observing mini-organisms from the pond as an alternative.
