Why Do We Get Dizzy? - Another Question from My Daughters

We're going to Storyland today for the sixth or seventh time this summer (it's one of our favorite family activities). My daughters love to go on a ride called the Turtle Twirl. I don't love it because it makes me quite dizzy and feel a bit of nausea. I've seen many other parents gingerly walk away from the ride. The last time we went to Storyland one of my daughters asked, "why do people get dizzy?" 

If you have children who are also wondering what makes people feel dizzy, SciShow Kids and PBS Kids for Parents have some good explanations to watch. The SciShow Kids explanation is suitable for a K-3 audience. The PBS Kids for Parents video is better suited to an audience of fourth grade through high school.

On a related note, TED-Ed offers a lesson on the mystery of motion sickness. The mystery for me is why do I experience it now (in my forties) but I didn't experience it when I was younger?
