FTCE: 5-9 IC Sci 6
FTCE Integrated Cirrculum 5-9 Competency 6: Nature of Science and lab rules
| Question | Answer |
|---|---|
| Most common dependent variable | time (t) |
| Body of knowledge systematically derived from study, observation, and experiments | Science |
| Pseudoscience | belief that is not warranted, such as witchcraft |
| Order of metric divisions .001 to 1000 | .001 milli centi deci base deca hecto kilo 1000 |
| 2 most common graphs in science | line graph and histogram |
| variable manipulated by experiment | independent variable |
| components of a lab report | title, abstract, purpose, hypothesis, control, observations, results, conclusion |
| scientific method | 1. pose a question 2. form a hypothesis 3. doing the test 4. observe/record data 5. draw a conclusion |
| rules regarding dissections (non living) | 1. use animals only from recognized sources 2. no decaying animals because of pathogens 3. rinse animals before touching 4. no sores/scratches/wounds 5. moral objections get an alternate assignment 6. Formaldehyde=carcinogen=>avoid! |
| uses sound waves to locate objects, especially underwater | sonar |
| Rules on live dissection specimens | 1. no mammalian vertebrates or birds 2. no physiological harm to any animal 3. handled in a safe and humane way 4. refusal to follow rules = suspended/fired |
| uses electrical charges of molecules and separates them based on size by pulling them through a gel box and attracting negative ions toward the positive side of the box and positive ions to the negative side of the box. | Electrophoresis |
| Spins stuff super fast so the dense parts of the solution settles - used to separate blood into plasma and blood cells | Centrifugation |
| uses principles of capillary action to separate substances like plant pigments - small molecules zip across the paper leaving pigment trails. | Chromatography |
| gives qualitative data on color changes by using light absorption percentages | Spectrophotometry |
| 1. Treat all organisms as if pathogenic 2. Always maintain sterile conditions | Rules for Microbiology experiments |
| 1. Know locations of fire extinguishers 2. Secure/pull back long hair and sleeves 3. Don't touch the barrel of the burner | Rules for using Bunsen burners |
| 1. Turn the gas all the way up and make a spark with the striker 2. Adjust the air valve until you see an inner cone 3. Adjust the flow of gas to the desired flame height | How to use a Bunsen burner |
| Used for precise measurements, should always be placed on a flat surface, measurement read at the bottom of the meniscus | Graduated cylinder |
| Setting a balance to zero before using it | tarring a balance |
| used to dispense precisely measured volumes of liquid | buret |
| used to control the volume of liquid coming out of a buret | stopcock |
| place a drop of water on the specimen and then put a coverslip on top of the drop of water, dropping the coverslip at a 45 degree angle to avoid air bubbles | creating a wet mount slide |
| How do you determine total magnification? | ocular number (usually 10x) times the objective number (usually 10x on low, 40x on high) |
| What should you rinse glassware off with before and after all experiments to keep everything sterile? | distilled water |
| Chemicals are stored in accordance with what factor? | reactibility |
