How is it possible that they are moving?
Geologists think that this is due to wind and mud but wind can’t move stones which weight as much as human. Some people think that this happens because of  freezing water at night in winter, which creates ice sheets.
Widespread winds in Death Valley are able to move the stones.

This is a grammar and vocabulary review activity (it is related to the world of art)
This is the way it works:
The teacher asks some questions so that students use known grammar in their answers (some will be more difficult than others).
Every time a student answers a question correctly they can click once on a slide to uncover part of a piece of art (or twice if the question is difficult). This will continue until a student guesses they type of art represented (portrait, sketch, etc.)
At the end of the activity the teacher and the students will do an assessment of the results.

Student:
- is familiar with the concept of polyhedron;
- recognizes and names spatial solids;
- shows practical use of spatial geometry in everyday life;
- finds elements of geometry in different fields, e.g. in chemistry, architecture, nature;
- uses simple calculation to establish the volume area and surface area of geometric models.

- Activity 1: Listening to the video and follow up which consists on asking and answering to some questions about the video they had watched.
- Activity 2: Study of the Eiffel Tower, France´s most famous architectural building .

Students work in pairs or in groups, depending on the number of students and computers in class.
