the three lenses with various magnifications on a microscope
New cards
8
natural magnification of the microscope
10x, so when you use an objective lens it takes the magnification of the objective lens and makes it x10
New cards
9
magnification of red objective lens
4x
New cards
10
magnification of yellow objective lens
10x
New cards
11
magnification of blue objective lens
40x
New cards
12
specimen stage
the area where the specimen sits
New cards
13
stage controls
two knobs that allow you to adjust the positioning of the stage (forward, backward, right, left)
New cards
14
stage clips
clip the specimen into place
New cards
15
control group
cultivated under normal conditions; sees if the experiment is functioning properly
New cards
16
experimental group
cultivated under the same conditions as the control group while changing one variable
New cards
17
independent variable
the variable that is changed in the experimental group
New cards
18
dependent variable
the variable affected (and measured) in the experiment
New cards
19
controlled variable
a variable that does not change from the control to the experimental groups
New cards
20
correlation
a relationship between two variables that may change together over time BUT won’t be connected by cause and effect
New cards
21
causation
the change in one variable will cause the value of another variable to
change (cause and effect)
New cards
22
quantitative data
involves numbers (more likely to be objective truths, as long as the
tools are being used correctly)
New cards
23
qualitative data
involves descriptions/adjectives (more likely to be subjective…could involve bias) - it’s not this data isn’t needed or valued, it’s just not typically the main dependent variable being measured
a coherent group of propositions formulated to explain a group of facts or phenomena in the natural world and repeatedly confirmed through experimentation and/or observation
New cards
26
law
statement, based on repeated experiments or observations, that accurately describes or predicts a range of natural phenomena
New cards
27
hypothesis
a supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation
