I like to end my Best of the Web presentations with fun sites. Lately, I’ve been ending my Best of the Web presentations with Who Pooped? Who Pooped? is an interactive site in which students learn about various animals by guessing which
animal created which pile of poop. Believe it or not, there is actually
some good information about the animals that follows each round of
guessing who created which poop. Cows are one of the that animals you can learn about on Who Pooped?

This week Larry Ferlazzo shared a neat video about the digestive tract of cows. In the video below a Rube Goldberg machine is used to show how a cow’s digestive tract works.
