How about getting him a beekeeping starter kit? This would allow him to start a beekeeping project, and he can continue expanding it as he learns more. Alternatively, you could get him some beekeeping tools, such as a beekeeping suit or a smoker, to help him maintain and work with his bees. Or, if he's interested in learning more about the science behind beekeeping, you could get him a book on the subject, such as "The Practical Beekeeper" by Michael Bush. Another idea might be to see if there are any local beekeeping classes or workshops he could attend--this would allow him to learn more about bees and beekeeping from experienced professionals, and could be a great way for him to expand his skills and knowledge.
Or you can get him a star map with an important date you share.
