One great gift idea for a science-loving grandson could be a science experiment kit! There are many different kits available, with different levels of difficulty, so you could choose one that would be appropriate for his age and skill level. Another idea might be a subscription to a science magazine or online resource, like Scientific American or NatGeo Kids, so that he can explore and learn about the latest scientific discoveries and advancements. Additionally, you might consider getting him a book about a famous scientist or a particular scientific topic that he's interested in, so that he can read and learn more about it outside of his regular studies.
Or you can get him a star map with the date when he was born.
