Investigating T. Rex's Bite
In Investigating T. Rex’s Bite, scientists explore the strength of the dinosaur’s bite using a pressure sensor and a crocodile. This video is excerpted from BBC's Horizon: T. Rex, Warrior or Wimp?, a documentary featuring interviews with T. rex experts from around the world and exploring the science behind the legend of the dinosaur we love to hate.
Lesson Express
Q: What are some similarities between T. rex and a crocodile?
A: The teeth, bite strength, predatory behavior, and limb structure are similar.
Q: What animals, still alive today, are similar to extinct animals that you could study to compare and contrast with T. rex?
A: Some animals that are still alive today that are similar to extinct animals are crocodiles, alligators, and sharks.
Q: What is the importance of a pressure sensor and what are some other ways it could be used beyond checking for the strength of a crocodile bite?
A: A pressure sensor can measure the amount of force or pressure that’s applied to something. In the clip, the sensor helped the scientists measure the amount of force of the crocodile bite. Other uses of pressure sensors include medical devices, weather, and cars.
