Los Alamos makes a great side trip from Santa Fe. I actually enjoyed it more here than there. This would be a great experience for a learning trip.
Bandelier National Monument--See ancient pueblos, burial and religious sites of the Anasazi tribe. Learn about their culture too.
White Rock--Eye-popping scenic overlook. Take pictures or meditate.
Bradbury Space Center--History of the nuclear testing at Los Alamos and the Manhatten Project. Other science stuff too.
Los Alamos Historical Museum--Visit and understand the history and culture of Los Alamos through the ages.
The Art Center at Fuller Lodge showcases the talents of local and regional artists. You can buy their work as well as view it.
Quick Tips:
If you're planning to do the day-trip from Santa Fe, be sure to stop at the tourist center before you make your stops. The people who work there are extra-friendly and will show you which sites you might be interested in seeing. No back-tracking, you just take the loop through town and head home.
You might want to plan to visit Bandelier before or after the afternoon because it gets so hot. We wanted to travel further along the trail, but we didn't bring enough water and we weren't used to the altitude.

Best Way To Get Around:
Car--It gives you freedom to see what you want, when you want. And you'll be covering a lot of miles too.
