Canadian astronaut Chris Hadfield, currently on a mission aboard the International Space Station, uses Twitter extensively to maintain a connection with Earth.

“Canadian astronaut Chris Hadfield, in orbit since December 21 aboard the International Space Station, does not lose contact with Earth, far from it. Mr Hadfield regularly informs the 122,000 followers of his Twitter account about life aboard the station, such as what he ate for lunch. He also posts numerous images of the blue planet. "

Today's activities will allow you to wow your students by showing them some of these pictures. At the same time, you will have the opportunity to familiarize yourself with Twitter. If you want to go further, you can invite your students to analyze the elements of Chris Hadfield's photos or to learn about the astronaut and his mission.


At the end of the activities, the student will be able to:
- use their knowledge to identify elements of aerial photographs;
- use their skills to analyze these elements;
- learn about a new use of Twitter (and, who knows, create an account there?);
- use the Internet to obtain information on the journey of astronaut Chris Hadfield;
- make a concept map to structure your ideas.
