A second internal or external hard drive can boot into a separate operating system on the same Macs.
Partitioning requires an erase of the hard drive. Together with partitioning, the Core2Duo (not CoreDuo, not CoreSolo), Xeon, Core i3, i5, i7 Macs which are Snow Leopard compatible can run both Snow Leopard and Lion, provided they have at least 2 GB of RAM. Older Macs indicated below can use the 10.6.3 retail installer, if not the 10.6 retail installer, if they are older than August 28, 2009. Machine ID is in Apple menu -> About This Mac -> More info (on 10.7 and later the About Window has System Information instead of More info to access the System Profiler) under the hardware section. You can find out which gray installer disc came with Macs that can install Snow Leopard newer than Maby reading.
