Basically you have 2 options. First one is to partition your OSX drive and to install each system on one of the partitions. It's the most convenient way probably and it does work for people but Pro Tools does not like it a lot to run from a partitioned drive in general. Second option is to run the second OSX from another internal or an external drive.
To get a well working Pro Tools system I would strongly recommend to use the internal OS drive in your Macbook for your music recording system (OSX Snow Leopard for example, whichever) only and an external drive for your daily use OSX El Capitan.
You didn't leave us the specs of your Macbook so we don't know what's the fastest port you have got for an external drive but you might use this one to connect the external OSX to your computer.
If you could get a SSD in an external USB 3 enclosure (given your Macbook already offers USB 3 ports) this would be ideal for such an application.
Check Amazon for a 250GB Samsung 850 Evo and an USB 3 enclosure for example which should not cost a lot nowadays.
If your computer still has got no USB 3, Thunderbolt (preferred) or FW800 may do the job. USB 2 might be too slow probably which might become annoying for daily usage.
What may help a lot to ease the whole procedure may be to use this little app to duplicate/clone your existing El Capitan installation to the dedicated external drive (you can use it to clone the system to any drive or partition of course).

It's called Carbon Copy Cloner and you can use it for free for 30 days. Download it, install it on your current system and clone the existing system to the external drive.
After that you could make a clean install of OSX Snow Leopard on your internal drive (important-wipe your drive before installing Snow Leopard, there should be no remainings of the El Capitan system!) and build up a fresh Pro Tools recording system on it.
Please, be aware of that Pro Tools 12 will not run on OSX Snow Leopard. You will have to use OSX Mountain Lion 10.8.5 (up to version PT12.4) or OSX Mavericks 10.9.x for PT12 at least.
If you should decide to use an older version of Pro Tools though, Snow Leopard will be a good and stable OSX for the use with an 002 indeed.
If you however should consider to make a fresh install of your OSX El Capitan as well, you can do it on your internal drive again and then clone it to the external like described above or you can install it on the external drive directly. If you would prefer to do it the second way, you will find a lot tutorials how to do that on the web. For example.

Finally let me say that Pro Tools always wants a stable and reliable OSX to work as supposed to and therefor it's the recommended way to install it on the internal drive of your Macbook and run the daily use OSX El Capitan from the external. You can try it the other way round as well but this will be no stable music recording system at the end of the day. For daily usage El Capitan via an external drive should work though.
So I hope this will help you further in a way.
The very best of success to you!
