American Museum of Natural History. Also, visit the Oculus maybe? If you're talking about today, warm enough for outdoor stuff, like High Line. If you like planes, go take the AirTrain and go plane spotting near JFK. If you have kids.....lots of stuff for kids. Botanical Garden train show might be another thing to catch as well.
9/11 museum is pretty interesting too. Free tickets avail for tuesday afternoons. MOMA free on Fridays after 4.
