Today's science standards encourage inquiry based activities and the best inquiry based activities result when an scientist and teacher collaborate. This activity was created by Dr. Alex Hastings, one of the scientists who helped discover Titanoboa, a large snake that existed 60 million years ago in South America. In this activity students will use the measurement of a Titanoboa vertebrae to estimate the size of the snake and the temperature that must have existed back then to allow the snake to get to such a large size.
