Science Trek
Science Trek is a place where parents, kids, and educators can watch short, educational videos on a variety of science topics. Every Monday Science Trek releases a new video that introduces children to math, science, technology, engineering, and math (STEM) career potentials in a fun, informative way.[MUSIC] Joan Cartan-Hansen, Host: The Earth's crust is made up of lots of sections called plates.
And during the time dinosaur roamed the earth, the surface of our planet looked very different.
When dinosaurs first appeared in the Triassic period, all the world's land were joined together in a super continent called Pangaea.
In the Jurassic period, the land mass had split into two continents: Gondwana and Laurasia.
And in the Cretaceous period, the land masses we know today were starting to appear.
With everything we've learned about dinosaurs, there are still some things we don't know.
We don't really know what dinosaurs sounded like.
We don't know what colors dinosaurs were except for the Sinosauropteryx.
It was orange with white rings down its tail.
And we don't know how many dinosaurs there really were.
But that's okay.
It gives us a chance to learn more.
Check out the science trek website for more information about this and all our science topics for kids.
