Group no. 6 EN212-01191 GHW2: Mechanism Description (draft) August 15‚ 2012 COMPOUND MICROSCOPE A compound microscope is an optical instrument used to see objects that are too small for the naked eye. A compound microscope is a microscope fitted with two or more convex lenses. The high magnification produced by these lenses together enables a detailed study of micro-organisms‚ cells and tissues. These types of microscopes are therefore widely used in scientific and medical research

Lab 4 Tissues Purpose: The purpose of this lab is to disover Histology or the study of tissues. Tissue make up a large part of our bodies and in this lab we will learn about the different types and functions of tissues. Hypothesis: I believe at the end of this lab If I am willing to do the reasearch the I will be able to use a mircoscope to look at different tissue samples and learn about the many types of tissue cells and their functions. Materials: The internet Book:Human Antomony

Pin hole camera was invented by a Muslim scientist ibn-al-haitham.An Egyptian polymath (born in Iraq) whose research in geometry and optics was influential into the 17th century; established experiments as the norm of proof in physics (died in 1040). Another inventor is the tenth century optician and physicist Abu Ali al-Hassan ibn al-Hassan ibn al-Haytham‚ simply known as al-Haytham‚ who invented the pinhole camera and discovered how the eye works. The ancient Greeks thought our eyes emitted

Practical 1- An experiment to observe the features of an Onion Cells Method: Gather all equipment that will be used for the experiment and check that they are clean and undamaged. Using forceps‚ peel the membrane from the underside of a small piece of onion. Place the membrane flat on a clean‚ glass slide and add one drop of iodine solution. Use a pin to carefully lower the cover slip over the slide‚ ensure there are no air bubbles before the use of the slide. Set the microscope to its lowest
