Which science project? I did so many of them growing up. Let see, um... Crystal set, Mua-ha-ha chemistry experiments, optical experiments. A microscope used to look at crystals, onion skin, pond scum, insect wings, blood cells, etc. A telescope to look at stars and do optical experiments with the primary mirror. Sending a house mouse I trapped up in an Estes rocket up to 800 ft, it survived and I let it go in the field. Photographic darkroom made from scratch with my first enlarger made from the telescope primary with the projection on a photo paper easel attached to the wall. A lot of mischief done.
