Are my kids just more inquisitive?

I've started to notice that my kids ask a ton of questions.  Like, more than classes I've had in the past.  Today we were watching March of the Penguins as a way to relax after a morning of stressful ISAT.  And my kids, especially Omar, Emon, DQ, Ty'najah, and Donnell, kept raising their hands as we watched.  Here are some of the questions they asked me:

• How do you know the difference between male and female penguins?
• Are the noises the penguins are making saying that they're cold?
• Can that type of wind blow a human away?
• What will the male penguins do if there's an avalanche?
• Is that saltwater or freshwater?
• Why doesn't the dad let the baby penguin go?
• Is this still happening [in Antarctica]?
• What about global warming [as to why the penguins are walking on large icebergs]?
• How do the parents know which baby is theirs?

I feel like these questions are really strong, some of the same questions I had as I was watching.  I wonder what the value of these questions is.  I mean, of course one value of questions is the investigation/research/learning that it stimulates.  Students may watch the video to find answers to their questions, they may seek out the answer in another source, or they may just act like penguins when we go out for recess (like Omar and Emon did, waddling around the jungle gym like penguins marching in Antarctica:-)  Whatever the case, I think the inquisitive spirit is part of what makes some one a smart person and good learner.
