Pine needles,
sliced thin
YOU WILL NEED
› 1 Slide, 1 cover slip, pipette, slicing tool,
tweezers, dissecting needle
› Water, pine needle
HERE’S HOW
1. Prepare a slide and take the slicing tool out of
the box. You will see a silver razor blade
inside the slicing tool.

CAUTION!
The razor blade is very sharp — so you will
have to stay sharp too! The dissecting needle
is also sharp. Be careful using both tools!
TIP!
You will always need a sharp
razor blade to cut your
specimens. The blade that
comes with the kit will
become dull over time. Be
absolutely sure to have an
adult help you change the
blade. Making thin slices is an
art unto itself and it requires
time and practice. It’s always
best to prepare several slices
at one time. That increases
your chances of getting a slice
of just the right thickness.
