Los átomos, también conocidos como las partículas indivis... Uy! No, espera!

¿¿Pero no decíamos que los átomos eran las partículas más pequeñas?? No, no, no. ¡Os mentí! Debo confesarlo, pero ahora ya os cuento la verdad.

Aquí tenéis la presentación. Ayúdate de ella para resolver el test que está debajo.

Dentro de la materia. Los átomos. from irenebyg

TEST.

Earthworm dissection.

Because it is widely known, Lumbricus terrestris goes under a variety of common names. In Britain, it is primarily called the common earthworm or lob worm (though that name is also applied to a marine polychaete). In North America, the term nightcrawler (or vitalis) is also used. In Canada, it is also called the dew worm, or "Grandaddy Earthworm". Although this is not the most abundant earthworm, even in its native range, it is a very conspicuous and familiar earthworm species in garden and agricultural soils of the temperate zone, and is frequently seen on the surface, unlike most other earthworms. It is also used as the example earthworm for millions of biology students around the world, even in areas where the species does not exist.

Worms are critical for soil turnover and fertility. They eat dead plant material, and their burrows help aerate the soil and let water through easily. Worm casts (faeces) are rich in recycled plant nutrients that help maintain soil fertility.

This practise consists on two parts:

A) First, there is a theorical study of annelids, specifically earthworms (Lumbricus terrestris).

Complete your worksheet, using this page Earthworm virtual dissection to do the exercises.

In this link you have the Virtual earthworm dissection worksheet.

WITHOUT COMPLETING THIS WORKSHEET, THE STUDENT IS NOT DOING THE DISSECTION

B) The second part of this practice, consists on observing the external features of annelids, and the earthworm internal characteristics. The practice guide is available in both links.

Check this video of how to dissect an earthworm.

Cómo crear un álbum de fotos en Google+

Ya que algunos tenéis problemas para crear el álbum de invertebrados, os dejo un "tutorial" sobre cómo crear uno en Google+.



Os recuerdo que también es útil para subir al Drive (que es un servicio de Google+, como "fotos") los ppt's, word's, pdf's, etc. Sobre todo esos que ocupan mucho y no pueden ser enviados por mail. Es mejor subirlos a la nube y pasarme el enlace (justo como hago yo por aquí con vuestros apuntes).

Un saludo! Espero que os ayude.

Atoms aka the ultimate particles of matt... oh wait :/

Weren't atoms the indivisible, ultimate particles of matter? Well guys, I have lied to you. I have to confess my crime. But now, let me tell you the truth.

Here you got the exposition about atoms. In a few days I might post a new test about it. Wait for it.



I also attach in here the video about atomic models you got in the PPT.



TEST


Have fun.

Heart dissection.

Before the practice, read the practice sheet and then complete this test about the heart dissection. I also link here two videos.
