One show that my son watches every morning is The Cat in the Hat Knows A Lot About That. I have been amazed at what he has learned from it. We were running errands to day and out of the back seat I hear, “Bats use echo location.” I was shocked. He may not understand what echo location is but it’s something that he’ll remember.
On a side note, the Cat is voiced by Martin Short. I thought he was dead!
