Instruments
used to measure linear length in cm
metric ruler
the first step in the scientific process
make an observation
the group that you leave alone
control
what is the structure you look through on a microscope
eye piece
something that you know happened
observation
Used to collect a larger material and allow the liquid to drip through, to separate mixtures
Filter paper
the second step in the scientific process
form a hypothesis
the group that you change the independent variable in
experimental group
what are the lenses at the bottom of the light microscope called
objective lenses
something that you did not see, but its occurrence seems like a logical outcome
inferance
compound microscope
the third step in the scientific process
perform an experiment
Independent variable
It is graphed on the x-axis
the larger button on the side of the microscope then the smaller button on the side of the microscope
coarse adjustment
fine adjustment
10X40=400
used to fairly precisely measure volumes of liquids
graduated cylinder
the fourth step of the scientific process
analyze the results
the variable that you measure after you change your independent variable and where it is graphed
the dependent variable
it is graphed on the y-axis
where the slide is placed
stage
cell, tissue, organ, organ system, organism
the correct order, from smallest to largest of the nested levels of organization of humans and other groups of higher level organisms
used to measure the mass of an object
balance
what you do after you analyze your results
report out or review you data if it is inconclusive and modify your experiment
a thing that is never changed
constant
where the light come from
light source or illuminator
population, community, ecosystem, biome, biosphere
The correct order, from smallest to largest of the nested levels or organization of organisms in relation to ECOLOGY-
