How old the kids, and what kind of limited budget are you talking?
If they are real young.....
I think something along the lines of incorporating the understanding of food production, the need for bees, and the ability to have the kids walk away with something in their hands would all be points to make.
How about a starter kit of some sunflower seeds, watermelon, or other plant seeds, along with a small potted pot, soil, etc. The kids can put together the pots, the soil, and plant a few seeds of their choosing. A 50 lb bag of sunflower seeds at Walmart cost around 25 dollars. The small pots can be bought for 10 or 20 cents a piece in bulk, and a few bags of potting soil is all that needed.
The kids can walk away with a pot, watch the plants grow, can transplant them outside when the time is right, etc.
Better than some "crafty" type thing that will soon be thrown in the garbage.
The lessons they could learn, along with the enjoyment of producing something, will be long remembered. And you can teach a lesson about bees while they are doing the crafts.
