If you serious about science - do not waste your money on this "Museum" as its completely not worth it. This is just an attraction for the kids with childish exhibits.
I would also not recommend to take audio guide as there a tiny amount of information provided.
In summary, my family paid for about $80 for frustration, and inside they tried pull more money from us.
Trams were closed at 3 PM (we missed it), although museum is closing at 5 PM.
Avoid this place and save your time/money if you visit Houston.
