Introduction to the BIO Lab I examined a puddle of mud sample and a soil sample collected the evening before, and a purple mold sample that was already in the lab. We saw microorganisms in the mud sample.

Research of some specific terms: -magnification: making images appear larger -resolution: ability to distinguish between two objects -slide: flat rectangles of thin glass -sample: something you collect to examine -specimen: the sample on the slide when you look at it through the microscope

Light microscope: it uses light in order to see an image | Electron microscope: it uses electron beams to see images (you can see a virus)

I collected different samples in the Ilm Park and examined them in the lab (spider web, tree bark, river water, mushroom spores, wet leaves). I found microorganisms moving in the river water and some little bugs both in the tree bark and in the spider web samples invisible to the naked eye. Mushroom spores were really interesting.

I examined again the mud samples: microorganisms were still there.
