Discover the science of living things with this complete introductory microscope kit. The beautifully illustrated experiment manual guides you through observations of many living specimens found in and around your home: onion cells, pond water, chloroplasts, plant stem cross sections, microorganisms, mouth cells, meat cells, different types of hair and fur, dust mites, bugs, pollen in honey, and much more. See how an onion cell shrivels and how an earthworm wiggles. Analyze the differences between the hair on your head and the sheep's hair in your wool sweater. The kit includes three prepared specimens on a slide, four blank slides, cover slips, tweezers, needle, section slicing tool, and vial. Learn how to use these tools to prepare slides and how to use the microscope to examine them. Investigate how the lenses in a microscope bend light to magnify images. The ocular lens, or eyepiece lens, of the microscope has an adjustable 12x to 18x magnification power. When combined with the three objective lenses, this results in a total magnification power of 96x to 750x. It has a battery-powered light and a mirror to light up the specimens. The full-color, 32-page manual covers microscope setup, usage, and many fascinating observations of biological specimens.
Introduce your students to the Five Kingdoms through the process of classification. Students view illustrations of various life forms and use a simple, dichotomous key to determine the appropriate kingdom and phylum of each. In the process, they'll gather valuable summary information regarding what each life form "does for a living!" Grades 6-12.
