  4. Microviewers • Inexpsensive? • Best characteristics is that they alloow the students to see images that they cannot see with the school microscope. • High school microscope magnify up to 400x • The micrographs on these filmstrips go up to 200,000x • Viewer = $9.80 15 filmstrips $177.00

  5. What is It? • Ant’s head.

  6. What is It? • This is the face of the Red Wriggler earthworm, Eisenia foetida. Earthworms burrow through the soil, eating dead plant material. As well as breaking down the dead plant material into soil, their burrows also help aerate it.

  7. What is it? • Common everyday items take on a new dimension at high magnification. In this photo, a staple is seen where it ripped through the fibers of a yellow sticky note paper.

  8. What is It? • These tiny glass capsules contain a liquid scent and are glued onto paper. When the paper is scratched, some of the capsules are ruptured and the scent is released.

  18. Microscope Care & Handling Importance of care So why do I need to know how to use the microscope? • Because microscopes cost several hundred dollars it is very important to make them last for a long time. How long will a microscope last if I take good care of it? • They can last for at least 10 years if you care for the "scope“.

  19. Microscope Care & Handling • Transporting • When you pick up the microscope and walk with it, grab the arm with one hand and place your other hand on the bottom of the base. • DON'T SWING THE MICROSCOPE !

  20. Handling & Cleaning • Never touch the lenses with your fingers. Your body produces an oil that smudges the glass. This oil can even etch the glass if left on too long. Use only LENS PAPER to clean the glass. • TOILET PAPER, KLEENEX, AND PAPER TOWELS HAVE FIBERS THAT CAN SCRATCH THE LENSES.

  21. Storage • When you are finished with your "scope" assignment, rotate the nosepiece so that it's on the low power objective, roll the nosepiece so that it's all the way down to the stage, then replace the dust cover. • DON'T FORGET TO USE PROPER TRANSPORTING TECHNIQUES!

  22. Clean Up: • Clean all slides, materials, and work area when you're done. Please, be careful with the slides and cover slips. They are made of glass and if broken, you will get cut and you will bleed.
