Teaching Earth History
Teaching how the Earth formed is one of the easiest parts of teaching Earth science because the kids are genuinely curious about how the Earth formed. There are also some great documentaries available on YouTube that will “show” the kids how Earth formed.
Another good thing about teaching Earth history is that the sequence is already created for you. Just start with the birth of the Earth and continue on until today.
Here are some interesting facts to share with your students while you are learning about Earth history. Sharing one of these crazy facts is a great way to start your class period because they will blow your students’ minds!
The oldest thing found on Earth is a 4.4 billion year old crystal called a zircon. It was found in Jack Hills of Western Australia.
When the dinosaurs lived on Earth, a year was only 370 days.
A day today isn’t 24 hours. It is 23 hours, 56 minutes, and 4.2 seconds. Our days are getting longer, and they have been getting longer for a long time. When the Earth first formed, a day was only 3 hours long.
If all of Earth history was represented by one year, humans would appear on December 31st at 11:00 p.m.
More time passed between when the Stegosaurus lived and the Tyrannosaurus rex lived than when the Tyrannosaurus rex lived and now. The Stegosaurus lived 150 million years ago, and Tyrannosaurus rex lived 65 million years ago.
The first pyramids were built while wooly mammoths were still alive. Most wooly mammoths died out around 10,000 years ago, but some wooly mammoths lived until 1650 BC. In 1650 BC, the Giza Pyramids were already 1000 years old.
Cleopatra lived closer to the building of the first Pizza Hut than the building of the Great Pyramid. The Great Pyramid was built in 2560 BC, Cleopatra lived in 30 BC, and the first Pizza Hut was built in 1958.
