Go to the archaeological museum at Sanxingdui. They have dug up some really interesting things there, different than any Chinese things I have seen before. You can do this and the panda centre easily in 1 day (do the pandas in the morning as that's when they feed them). There is a second panda centre at a panda reserve but it's quite a way from Chengdu so I don't know if you can go there in a day trip.
