• You will be put in groups of two and will
be assigned a station
• You will have 3 ½ minutes at each station
and I will tell you when you can move to
the next station
• You must draw what you see in the
microscope on your worksheet
• DO NOT PUSH THOSE THAT ARE LOOKING
INTO THE MICROSCOPE
• DO NOT ADJUST THE MICROSCOPE,
BECAUSE YOU WILL LOSE THE IMAGE
All living things:
•are made up of cells (organization)
•respond to the environment
•have the ability to reproduce
•move
•grow and develop
•perform metabolic processes

•The cell is the smallest unit of a living thing
•If an organism is unicellular, all functions of
life happen within that one cell
•If an organism is multicellular, different cells
have different jobs and they all work together
•all living things are made of one
or more cells
•the cell is the smallest unit of life
•all new cells come from
preexisting cells
1660’s – Robert Hooke discovered the cell
• He looked at cork under the microscope (30x)
• He noticed little compartments, which he named after
•the little rooms that monks lived in…”Cells”
1670’s – Anton von Leeuwenhoek described
microorganisms in pond water
• He looked at pond water under the microscope (300x)
• He noticed that the water was full of moving living things
M.J. Schleiden
Theodor Schwann
They discovered that the cell was the basic unit
of life and that all living things are composed of
cells
20 years later
Rudolf Virchow
concluded that
all living cells
arise from
preexisting cells

You will be grouped in four groups of five
You must come up with a 2 minute rap/song
to help you remember what the cell theory is.
You must include the three components of
the cell theory in your rap/song.
