What are the six steps to the scientific method (in order)? 1. Observe/state a problem 2. Form a hypothesis 3. Experiment: materials and procedure 4. Collect and analyze data 5. Draw conclusions 6. Replicate your work
Observing Using one or more of the five senses to perceive objects or events
Hypothesizing Forming testable statements about observable phenomena
Predicting Stating in advance the results that will be obtained from testing a hypothesis
Experimenting Testing a hypothesis or prediction by carrying out data gathering procedures
Measuring Determining the dimensions of an object, number of objects
Collecting data Gathering and recording of specific information based on observations
Organizing data Placing observations and measurements in some kind of logical order
Classifying Grouping objects, organisms, or phenomenon
Modeling Helps show relationships between data
Analyzing data Determining whether data re reliable and whether they support or refute a given prediction or hypothesis
Inferring Drawing conclusions on the basis or premises instead of direct perception
Communicating Allows scientists to build on the work of others
What is a hypothesis? A testable statement

What is a theory? Most probable explanation for a set of data based on the best available evidence; Explains WHY things happen
What is a law? General statement that describes a wide variety of phenomenon; Explains HOW things happen
Eyepiece Look through to view the specimen
Ocular lens Magnifies
Arm Main upright support for the microscope
Base Main support for microscope
Stage Holds the specimen
Iris diaphragm Regulates the amount of light that passes through the stage
Stage clips Holds the specimen in place
Light source Focuses light through the specimen to the lens
Objective lenses Magnifies the specimen 1. Scanning-4x 2. Low power-10x 3. High power-40x 4. Oil immersion
Revolving nosepiece Holds two or more objective lenses and can be turned easily
Coarse adjustment knob Brings the specimen closer or father away from the lens
Fine adjustment knob Fine tunes the focus of the lens
How is total magnification determined? Objective lens x Ocular lens
What are the three rules for properly carrying a microscope? 1. Hold it against your body 2. Use one hand to hold the base 3. Use the other hand to hold the arm
The iris diaphragm functions like what eye structure? Pupil
What is magnification? The enlargement of an object
What is resolution? A microscopes power to show detail clearly
What is diffraction? Bending of light waves
What is the relationship between magnification and field of view? As magnification increases, FOV decreases
What is centrifugation? Separating cells by spinning fractionated cells at high speeds
What is electrophoresis? Separating DNA on the basis of their electrical charge and size
What is cell culturing? Growing a population of identical cells in the laboratory
What is chromatography? Separating chemical components of a substance by passing them through a piece of paper or a column of beads
What is a characteristic of organic molecules? Contains carbon (carbon backbone), derived from living things
What is characteristics of inorganic molecules? No carbon, derived from non-living things
What is the general equation for a condensation reaction? monomer + monomer = polymer + H2O
What is the general equation for a hydrolysis reaction? polymer + H2O = monomer + monomer
What is a polymer? Many units formed by monomers
What is a monomer? One unit, makes up compounds
