Scientists carry out experiments on bees to analyse their pollinating and stinging habits.
M/S of a female beekeeper squatting next to a beehive, she gets up and moves over to another hive. C/U of the beekeeper opening a jar of yellow powder and brushing it onto the hive. The beekeeper is a scientist at the Rothampsted Experimental Station researching the movements of bees. Extreme C/U of bees brushing against the powder as they leave the hive. Different coloured powders are used to assess the habits of different hives.
Top shot of a vole and some cotton wool balls in a glass container. A scientist, Dr. John Free reaches in and takes a cotton wool ball. M/S of Dr. Free attaching the ball to string at the end of a long pole - a ball without the vole's scent is also attached. Dr. F. walks to the hive. C/U of the pole poking the hive to provoke the bees to attack. M/S of Dr. F. examining the balls. C/U of Dr. F. counting the number of stings in the balls - there are more in the ball with the vole scent suggesting animal smells make bees sting. Dr. F. leans the pole against a garden urn and picks up a board with black and white balls attached to it. He walks to the hive and lifts off the lid. C/U of the lifted lid exposing a squirming mass of bees. Panning shot of the board being lifted and held over the bees. By shaking the board Dr. F. can discover which balls the bees are more likely to sting - the black or the white. Dr. F. shows the board to the camera. C/U showing more bees stinging the black balls. Panning shot of the white board being swapped for a yellow board. The beekeeper repeats the experiment with the yellow board - this time the bees sting the white balls. The narrator explains if the board had been white more bees would have stung the yellow balls as they are affected by contrast and colour.
L/S of a field of yellow flowers, several students are collecting bees from the petals. M/S of a female student's legs wading through the flowers. Extreme C/U of the hands of the student scooping a bee from a flower into a tiny glass container of anaesthetic.
Once they have been "drugged" to sleep, a scientist analyses the type of pollen the bee has collected. M/S of a female scientist sitting outside at a desk. Extreme C/U of the scientist's hands removing the bee's pollen sack with tweezers and placing it in a numbered container. The scientist marks the bee so it can be identified. Extreme C/U of her hands painting the bee's abdomen white. C/U of the scientist dropping the bee into a wooden box for later release.
