DO’s








Use water droppers and iodine to
make a proper wet-mount slide
Look at cheek cells and Elodea
plant cells under the microscope
Be patient – seeing this stuff can be
difficult! Look carefully and
persevere.
Use forceps and scissors to
manipulate specimens on the slides
Work quietly and productively w/
your assigned partner
Clean up by rinsing slides as the
sink by your lab table
Put Elodea leaves in the trash when
cleaning up
Put notebooks away, put bags
under your chairs. Take only the
lab packet and a pen/pencil back
to your lab station.
DON’Ts







Don’t squirt water or iodine
anywhere other than on the slide
Don’t put anything else on
microscope slides (pen ink has
ruined some slides!)
Don’t stick/cut anything else with
forceps or scissors
Don’t move to other tables or talk
across the room
Don’t move across the room to
clean up or get materials. If you
need something, raise your hand!
Don’t rinse leaves down the drain!
Take anything other than the lab
packet and a pen/pencil to your
lab table.
