Scotland is mostly famous for the Loch Ness Monster, Bagpipes, Kilts and Whiskey. We went in 2017, and were stunned by it's nature and beautiful highlands and even mountains. We went hiking, saw cliffs and waterfalls, castles and ruins and of course tried the local whiskey.
The first thing to mention about National Museum of Scotland is, that it is free. I was at the museum in 2017 and the section that spoke to me the most, was the Science and Technology Gallery. Here was planes, motors, electronics, race car simulators, robots and a bunch of things you could interact with. Also the Natural World gallery is worth my recommendation. The many skeletons and life-like figures are fantastic Of course Scottish history and archaeology is on of the topics in the museum. There is also a vast number of other exotic cultures represented in the World Cultures Gallery.
