How about a telescope or a star chart so you both can stargaze together? Or a chemistry set with all the tools for her to conduct experiments at home? You could also consider getting her a science-themed book, such as "The Elements: A Visual Exploration of Every Known Atom in the Universe" by Theodore Gray, or tickets to a science museum or planetarium. Another idea could be a personalized DNA artwork, where you have her DNA sequence turned into a piece of art. This would be a unique and personal gift that would also be related to science.
