Aim #12: What are some other tools biologists use in the laboratory? Date: September 29, 2016 Aim #12: What are some other tools biologists use in the laboratory? HW: Characteristics of Life Worksheet Castle Learning due Wednesday Unit 1 Test Thursday (p.1) & Friday (p.5) Do Now: How many micrometers are in 1 millimeter? Which part of the microscope controls the amount of light passing through the specimen? How do you calculate total magnification? Which parts of the microscope do you use to focus a specimen?

1. How do we prepare a wet-mount? Place drop of water on slide Place specimen in water Place cover slip on a 45º angle to avoid air bubbles

2. What is an Electron Microscope? Uses beams of electrons (NOT light waves) to produce magnified image specially fixed and treated and mounted in a vacuum

How do they improve images? High magnification Greater than 100,000X High resolution: the ability to separate two objects close together

3. What is a stereoscope? AKA: Dissecting Microscope Binocular: two tubes Presents a slightly different view of specimen to each eye… 3D Useful for opaque objects and small organisms or body structures

4. What is a centrifuge? AKA: ultracentrifuge Separates according to different densities by spinning sample in a test tube at very high speeds

5. Why do we stain cells? Cell Structures can be made visible by treatment with solutions that color certain parts of cells and not others

6. Why do we use indicators? Substances that change color when in the presence of certain chemicals
