Today, I took my kids to the Ontario Science Centre to see the IMAX film "Island of Lemurs: Madagascar" and check out The Science of Rock 'n' Roll experience. Both were pretty awesome.
"Island of Lemurs: Madagascar" is what you'd expect from a Morgan Freeman narrated IMAX movie about Lemurs, which is to say it's excellent. There's a lot about these cute little guys you likely don't know, and all of it is rather fascinating, and I'm a sucker for anything IMAX.
But the real attraction at the Science Centre these days is The Science of Rock 'n' Roll exhibit, and it's only here for a limited time. If you love music, you could easily spend an entire day reading about the history of rock, watching the many informative videos (narrated by Alan Cross, no less) and mixing, recording your own music.
The kids loved the hands-on interactive components, as did I. The hardest part is letting them have their turn.
Any time you can combine rock with science, you've got the perfect activity for the kids this summer. Throw in an IMAX film and you've got yourself a day to remember.
