EXPERIMENT 11

Hunting for pollen in a

honey sample

YOU WILL NEED

› 2 slides, 2 cover slips, pipette

› 1 water glass, 1 teaspoon, 1 flat saucer,

natural honey (ordinary quality from the

supermarket), 1 permanent marker (for

marking the slides), 1 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.
