Levenhuk LabZZ M3 Microscope will become an indispensable assistant for parents of curious children. This is a microscope that will captivate a child for a long time and impart the joy of new discoveries. Included with the microscope are 100 accessories for scientific experiments, sample preparation, and microworld exploration. The microscope’s prime feature is its eyepiece projector that will project desired images on a wall or blank sheet of paper.

The projector reflects images captured by an objective lens on any surface. It should be placed directly into the eyepiece tube. The darker the room, the clearer and sharper the images will be. Using the projector, children can share their achievements in science with family and friends.

The microscope provides three fixed magnifications – 300x, 600x and 1200x. You can switch them by rotating the revolving nosepiece. Image sharpness is easily adjusted with a separate knob on the microscope body. Samples should be placed on the microscope stage and fixed with special metal clips.

Looking for something to start your observations with?

Paramecium caudatum is perhaps one of the first protozoans that a young naturalist would explore. These organisms live in fresh standing water. They can also be found in an aquarium, especially if it hasn’t been cleaned for a long time. My ciliate-shoes were taken from the aquarium. Of course, there are only a few ciliate-shoes in aquarium water – the possibility of finding one of them in your microscope’s eyepiece is extremely low. Therefore, we need to increase their concentration. To do so, take a jar (about 17 fluid ounces or 0.5 liters), fill it with aquarium water, put a small spoiled onion and banana peel inside. Put the jar in a warm dark place for 5 to 7 days (don’t close it with a lid).

 

 

Paramecium caudatum. Animation. Magnification: 64x.

 

The average size of Paramecium caudatum is 0.02 inches (0.5 mm). For locomotion Paramecium caudatum uses its cilia (about 15 thousand cilia cover its little body!). Moreover, it has two nuclei (a large macronucleus is responsible for nutrition, respiration, metabolism, etc.; and a small micronucleus – for reproduction). Paramecium caudatum feeds on bacteria or algae. The food is caught by an oral groove covered in cilia and then goes to the cell mouth. It is then digested in the digestive vacuole (gullet). Undigested leftovers are ‘thrown out in the open’ through an anal pore (cytoproct). To remove all excess water, our heroine has two contractile vacuoles. They work like pumps on a boat, pumping excess water out of its body. Paramecium caudatum maintains its slipper-like shape thanks to a special membrane (pellicle).
