This page will collect the contributions from the teachers who have used this unit, in total or in part, in the classroom. 

Initially it just contains a few "teaching suggestions" which we could call "theoretical", although they are based on our teaching experience. 

The work with "The Earth and the Universe" in the classroom will no doubt be the source of more important contributions. The teaching unit is organized as follows: 

Initially it is intended that the students

• Understand in a qualitative manner the notion of relative movement, to a sufficient degree to be able to explain the apparent movement of heavenly bodies as a consequence of the rotation and  translation of the earth. 
• Explain in terms of these same movements the succession of days and nights, as well as the seasons of the year. 
• Know the components of the Solar System and some of its most interesting properties.
• Understand the analogous nature among the Sun and other stars, as well as acquiring a notion about its origin, the causes of its energy emission and its probable destiny.
• Explain the night sky as a way of seeing our galaxy, the Milky Way. 
• Understand the enormous quantity of galaxies which exist in a Universe perceived according to its evolutionary character. 

All types of contributions, like the time it took to work on the unit, incidences, proposals for improvement, criticism, positive points, etc. are welcome at:
