Scientific and Microscope Flashcards
(T or F)
The conclusion is supported by the hypothesis, the it is regarded as false
F
(T or F)
Problem is considered scientific if it ca be resolved by gathering observable and measureable evidence
T
(T or F)
Problem is considered a scientific if the method of resolving is not repeatable
F
This is a series of step by step procedure that scientist and science student go through and sometimes steps are done in order, but often order change depends on the result
Scientific Method
What are the steps on your answer in previous question
Observation
Define problem
Propose hypothesis
Experimentation
Draw conclusion
3 main parts of the microscope
Mechanical
Optical
Illuminating
Define the parts whether it is Mechanical, Optical, or Illuminating
Arm
Base
Eyepiece
Condenser
Mirror
Coarse adjustment
Objective lenses
Diaphragm
Revolving nosepiece
Arm = Mechanical
Base = Mechanical
Eyepiece = Optical
Condenser = Illuminating
Mirror = Illuminating
Coarse adjustment = Mechanical
Objective lenses = Optical
Diaphragm = Illuminating
Revolving nosepiece = Mechanincal
The word science is from what greek word? And what is the meaning of this word?
Scientia means Knowledge
Step in scientific method which you notice something and give causes to the scientist to think and ask a question
Observation
Step in scientific method that gives tentative answer
Proposing of Hypothesis
Step in scientific method that gives the result of the research
Drawing of conclusion
Magnification of HPO
40x
What oil is used in OIO?
Cedarwood Oil
Magnification of OIO
100x
Type of objective lenses that focuses the initial image
Low Power Objective or LPO
Part of Microscope that holds the slide
Stage clip
Part of Microscope that avoid accumulation of dust in objective lenses
Draw Tube
Type of Microscope that has more than 1 lenses (2 lenses; 1 eyepiece and objective lenses)
Modern Compound Microscope
This type of Microscope is developed by Robert Hooke in year 1665 and it has a oil lamps and condensing leses
Laboratory Compound Microscope
This type of microscope does not use lenses but uses electrons that magnifies up to 300 000x
Electron Microscope
Objective that gives larger image
Low Power Objective or LPO
What is the effect of shifting HPO to LPO on the microscope field?
It narrows the microscope field and a certin portion is further magnified
Magnifies a minute object and not seen by the naked eye
Microscope
Type of Microscope discovered in year 1672 by Anton van Leeuwenhoek. What is the magnification?
Simple Microscope magnifies 200x-300x
Microscope made by Zaccharias Jenssen and his son Hans Jenssen in year 1590. What is the magnification?
Simple Compound Microscope magnifies 100x - 200x
This is a objective that covers wider field
High Power Objective (HPO)
Importance of Microscope in the study of science?
Enable us to view and magnify organisms and stuctures which cannot seen by the naked eye
Step in scientific method where you ask questions like what, how, and why
Define problem
Type of objective lenses that has 4x magnification
Scanning or scanner
What is the position of letter “e” under the microscope and what is the direction of this when you move left, right, up, and down
The letter “e” is inverted under the microscope. The direction of the letter “e” when you move it to the left, it will go to right. Move to right, will go to left. Up will go down and down will go up
