Vamos a la segunda clase de Astronomía para este primer curso de primaría. Así que vamos a hacer una actividad sencilla: vamos a construir un sol de papel y cartón. Para ello necesitaremos:
- un plato de plástico
- cartulina amarilla y naranja
- papel amarillo (papel mache, papel fieltro, goma eva....)
- temperas o pintura amarilla
- rotuladores o temperas de colores para decorar
- tijeras y pegamento
Aquí os dejo un vídeo de como hacerlo.... ¡ es muy sencillo!.

Good evening, students. I am very pleased to report that the class has done well on the assignments from last week. Many of you have attempted the extra credit, which makes me very happy. For those of you who have not done the extra credit yet and still wish to complete it, please do so - although it is optional, the extra credit is very easy, and it will also help both you and me make this Astronomy class a better experience for us all.
Today we are going to learn about our Star:The Sun
Astronomy 102. The Sun
The Sun, a hot ball of hydrogen and helium, is the source of all the energy and magic in the solar system, aside from the miniscule amount we get from the other stars. As we have learned in previous lessons, the amount of magic we receive from a celestial body depends on the amount of light it sends us, as well as its size, and the Sun’s average diameter is 1,391,980 kilometers, about ten times as great as the largest planet! It also sends us the most light - about 400 thousand times as much as the full Moon and 12.5 billion times more than the next brightest star, Sirius. Its surface temperature is about 10,000 degrees Fahrenheit. It actually has a name – Sol, the Latin word for sun – which is where the word “solar” comes from. While the Sun is undoubtedly important, more details will be provided about this blazing behemoth in your Fifth Year, so now we turn to the planets.
