A wealth of interesting discoveries awaits your kid with Levenhuk LabZZ MT2 Microscope & Telescope Kit! The kit includes a biological microscope with an experiment set and a refracting telescope. These instruments feature high-quality optics, reliable design, and convenient use. The guide is written especially for the youngest explorers in a user-friendly and easy-to-read manner. The kit is designed for children over 6 years of age. Teenagers will also enjoy exploring the skies or the micro world with Levenhuk LabZZ MT2.

Telescope

Levenhuk LabZZ MT2 Telescope is a refractor that uses lenses to gather and focus light. Its 50-mm objective lens allows for both astronomical and terrestrial observing.

The telescope comes with two eyepieces. The H12.5 mm eyepiece (50x) is used for observing astronomical objects such as the Moon and Solar System planets. 18-mm erecting eyepiece (35x) helps you get direct (not inverted and not mirrored) images of observed objects – that’s why it is convenient to use for terrestrial observations. The erecting eyepiece can also be used as a pocket microscope with 14x magnification power.

The telescope is installed on an easy-to-use altazimuth mount, which allows for moving the tube horizontally and vertically. A compact table tripod provides a stable and reliable base for the instrument.

Microscope

Levenhuk LabZZ MT2 Microscope is designed for observing transparent samples. The kit includes three eyepieces producing 75x, 300x, and 900x magnifications. Convenient revolving nosepiece allows for quick magnification switch.

To start observing, place a sample on the microscope stage located above the mirror. If the illumination provided by the mirror is not enough, use the built-in illumination source.

The kit includes everything needed for working with the microscope, as well as an extensive set of ready-to-use microscope slides and instruments for preparing new slides.

The kit includes:

• Telescope
• H12.5mm eyepiece
• 18mm erecting eyepiece

Paramecium caudatum - your first friend from the microworld

11/21/2016

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).
