It's not as modern as OMSI in Portland (Oregon Museum of Science and 
Industry), but you have to remember that the Exploratorium is 
self-supporting, and relies on a lot of volunteers and interns.  Even as 
an adult I learned a lot from going through it, especially in regard to 
the light wavelengths given off by burning of various gasses on the sun 
as viewed through a spectrograph.

Unless they changed it in the last few years, I don't remember much 
remarkable about the Griffith Observatory except the pendulum.  The rest 
was so-so to me.  Well, it has been a few years...

The Morrison Planetarium is one of the best in the world.  Its star 
projector is a model upon which most current projectors are based.  
Instead of using round holes in creating the stars on the projecting 
lenses, they use little grains of sand or something giving jagged edges.  
The eye perceives these as points of light rather than does, as is common 
with other planetarium projectors.  It is truly an awesome show.
