1 Time to be real scientists!

2 For years we could not figure out the circulatory system! Could see veins, arteries, heart, etc … They knew the blood got back to the heart but at a certain point … nothing could be seen connecting them! Enter … Marcello Malpighi

3 Was examining frog tissues when he discovered a network of tiny veins and arteries! Capillaries  Latin for “hair”

4 Humans eyes can only see clear, defined images that are 0.1mm or larger. Whole world we cannot see Enter 1600 century and BAM …!

5 Compound Light Microscopes! compound microscope Two or more lenses = compound microscope! Why compound LIGHT microscope? Light/lamp located at base Microscopes magnify tiny items
