Gloves

Ok, this is not a question that's specific to schools - but what kind of gloves should you wear?

Nitrile gloves - the best option

Marigolds - good middle ground

I bought a pair of leather gloves when I first bought my suit a year or so ago, but intend not to use them. Why? They are too chunky and clumsy and impossible to wash. As I have passed the bee-sting test, I am not afraid of getting stung and therefore do not need that thick protective skin. On the contrary, you need all fingers sensitive if you want to pick up the queen, or similar. So, either go for marigold washing-up gloves (if you like a bit more protection) or nitrile throwaway gloves (with a longer cuff, though). In terms of hygiene these are much the best, if not necessarily for the environment. Change the gloves each time and you won't be carrying around pheromones of past stings or past happenings in the hive that might upset the bees. You will also not be carrying around any germs.

Classic leather beekeeping gloves

However, for the children, we will get leather gloves as here protection is more important and they will not be doing sensitive manipulations with the bees. Currently, we are checking what the cheapest way is of obtaining leather gloves (and checking suppliers of fencing gear, too). 
Over these the pupils will wear nitrile gloves, too, for reasons of hygiene.
