One idea might be to get your grandson a beekeeping starter kit that's specifically designed for urban beekeeping. Another idea could be to buy him a book about beekeeping or urban gardens featuring information on bees, their importance to the ecosystem, and how to keep them healthy in an urban environment. Lastly, you could consider enrolling him in an urban beekeeping class that can teach him the ins and outs of beekeeping and connect him with other enthusiasts.
Or you can get him a star map with an important date you share.
