BBC Earth offers this interesting look at their 25 choices for the biggest turning points in Earth's history. Scroll through to learn about events beginning with the birth of Earth 4.5 billion years ago to the evolution of the human race 200,000 years ago. Each event includes approximate dates and a short description of the occurrence. Some events include animation. See these by clicking "Play Video." At the time of this review the animations were problematic using Safari. The site was created in the UK, so some of the pronunciations and spellings may differ from those in American English.
This site includes advertising.

In the Classroom

Ask students to consider the question of the 25 biggest turning points in Earth's history before viewing this site together then compare responses. Have students brainstorm or collect ideas on a collaborative bulletin board like Scrumblr, reviewed here, (quick start- no membership required!). Use this site as inspiration for students to create their own 25 (or whatever) choices for the biggest turning points in their life, your state, their country, a country they are studying, or any subject they are studying.
