THE EARTH

Activity for Sergio and his friends at 3º primaria.
THE SOLAR SYSTEM has a star, the SUN, planets (MERCURY, VENUS, THE EARTH, MARS, JUPITER, SATURN, URANUS & NEPTUNE) and SATELLITES ( THE MOON)
THE EARTH is our planet and it has LAYERS: the ATMOSPHERE (air), the HYDROSPHERE (water), the BIOSPHERE (living organisms) & the GEOSPHERE ( a big ball of rock with layers too: the CRUST, the MANTLE and the CORE)

The Sun, the Earth and the Moon move. That's why the Moon has different shapes: the PHASES OF THE MOON: WAXING CRESCENT, FULL MOON, WANING CRESCENT and NEW MOON. You can make the Moon Phases with Oreo cookies:

As the Earth moves, that's why there are four SEASONS: SPRING, SUMMER, AUTUMN & WINTER:

What's your favourite season? Sergio's is Winter!! because he loves Christmas :  )

This is a song you have listen to in class, it's taken from youtube:
