Hunting for pollen in
a honey sample
You will need
2 Slides
– 2 Cover slips
– Pipette
Water glass, teaspoon, flat saucer, natural
honey (ordinary quality from the
supermarket), permanent marker (for
marking the slides), piece of blotting paper
(or paper towel), water
Here’s how
1. Get everything ready — slides, cover slips, and
all the other items. Label the slides with the
type of honey (wildflower, etc.) or the brand
name.
2. Dissolve about half a teaspoon of honey in
some water in a water glass. Then set the
spoon on the saucer.
3. Now use the pipette to suction up a little of the
solution (one sample from the bottom of the
glass, and one from higher up) and drip the
two samples onto the two slides.
4. Place a cover slip on each slide, carefully blot
up any extra liquid, and study the samples
under different levels of magnification using
the microscope’s different color filters.
5. After completing your observations, pour the
remaining honey-water mixture down the
kitchen sink drain and rinse it down with
water. Clean the pipette, slides, cover slips,
water glass, and spoon right away with some
dishwashing liquid, and place everything on a
kitchen towel to dry.
