2.1. SCIENCE (scientific fundamentals)
2.11 Nature of Science (Scientific Fundamentals)
2.12 Scientific Method
2.13 Controlled Experiment
2.14 Theory and Law
2.15 Scientific publications
2.2. INTERNATIONAL SYSTEM OF MEASUREMENTS (Metric Measurements)
2.3. MICROSCOPY
AT THE END OF THIS LECTURE, YOU SHOULD BE ABLE TO:
1. Differentiate between science, non-science, and pseudoscience.
2. Explain the underlying assumptions and the limitations of science, and understand that scientific 'fact' may change with changing scientific knowledge.
3. List the steps in the scientific method.
4. Explain the purpose of a controlled experiment, and understand the difference between a control group and a test group.
5. Differentiate between a scientific hypothesis, a scientific theory, and a scientific law.
6. Discuss scientific publications.
7. List the reference units for scientific mass, length, volume and temperature measurements (the SI-system "metric" reference units), list and understand the SI-system prefixes, and know some standard temperature points in the three temperature scales (Celsius, Fahrenheit and Kelvin).
8. Know how to use a microscope including the meaning of the term parfocal, know the various microscope parts, understand depth of focus / field of vision and understand how to calculate the total magnification.
9. Define selected key terms.
List the steps in the Scientific Method (in correct order, as five steps -- as discussed in class): 1. __________________________
2. _________________________ 3. ________________________ 4. _________________________ 5. ________________________
List four underlying assumptions of science: (select from the following: value, testable, tentative, scientific method, natural, uniformity, five senses)
6. Science deals only with what we can perceive with the basic __________________________________________.
7. What we perceive function according to the principle of ______________________________________________.
8. All events are caused by ___________________________________ phenomena.
9. Science discover and attempt to understand phenomena by a systematic form of inquiry called the _______________________________.
List three limitations of science: (select from the following: value, testable, tentative, scientific method, natural, uniformity, five senses)
10. Scientific conclusions are always __________________________________________.
11. Scientific hypothesis must always be ______________________________________________.
12. Science cannot deal with subjective _________________________________ judgments.
SI System:
13. Give the reference unit for a. length, b. volume, c. mass (weight), and d. temperature:
a. ________________________, b. ________________________, c. ________________________, d. ________________________,
14. Boiling point of water: __________°C (= __________°F), 15. Freezing point of water: __________°C (= __________°F)
16. Normal human body temperature: __________°C (= __________°F) 17. Temperature in a freezer: _________°C (= ________°F)
18. Absolute zero: ___________°C (= ___________°F) 19. Milk pasteurization temperature: _________°C (= ________°F)
20. Weight measurements: 1 g = 10 dg = ______________cg = ______________mg = ______________µg = 1,000,000,000ng
21. Length measurements: 1 m = 10 dm = _____________cm = ______________mm = 1,000,000µm = ________________nm
22. Volume measurements: 1 l = _____________dl = 100cl = 1000ml = ______________µl = ________________nl
23. Computer memory: 1,000,000,000 byte = 100,000,000 dab = 10,000,000 hb = ______________ kb = 1,000Mb = 1Gb
24. Length measurements: 1,000,000,000 m = 100,000,000 dam = 10,000,000 hm = 1,000,000 km = ______________ Mm = ______________ Gm
25. It is easy to understand the SI system if one understands the terminology. The words kilo and milli BOTH mean thousand.
As prefixes in the SI system kilo stands for _________________ and milli stands for _________________. The world kilo is used when converting up, while milli is used when converting down.
26. Which of the lecture objective(s) (see list above -- not counting the key term objective) was/were not covered in the quiz above? ____________
