Here you can see different ecosystems and the difference between populations and community in an ecosystem.

This is the best way to show you how an ecosystem works with the different trophic levels.

Insects and arthropods. Living things

We are studying the invertebrates and there is a big group called ARTHROPODS, these are all the insects you can see and last year in an excursion we could see some of them.  Some of those are from our stick bugs.

On this picture you can see the skin of a Mantis after it changes the external exoeskeleton. This is called the molting process.

Cuidando nuestro acuario. 4EP Natural Sc

Hoy los alumnos de 4º hemos estado cuidando y poniendo a punto el acuario para posteriormente introducir algún pez en nuestro pequeño ecosistema. :

  • El tanque: donde pondremos todos los elementos naturales. Todas las plantas son naturales y no hay nada de plástico.
  • El termostato que calienta el agua para que la temperatura siempre este a 25 grados que vemos con un termómetro.
  • El compresor: que produce aire para que el agua esté siempre con óxigeno y aireada.
  • El filtro. En nuestro caso este acuario tiene un filtro ecológico y externo. Este filtro tiene un material orgánico y varias esponjas que permiten un filtrado óptimo.
  • Un comedero automático qu echa y administra comida 2 veces al día.

Hemos limpiado el filtro y explicado todas las partes esenciales del acuario. También hemos empezado a ver cómo pueden convivir las especies dentro del acuario.

Iremos profundizando a lo largo del curso con la población y diferentes especies de peces.

ACUARIUM. Water Ecosystem Project. 4º, 5º EP

During these days the children have been creating an excellent water ecosystem for tropical fish. Of course we did the first steps and now we have to wait to have the big fish you will see in this video. The fish you see at the end of the video lived in the same acuarium last year. In the arts and crafts class we decorated the posters for the instructions and now we are ready to write more things…

Now it’s your turn if you want to look after them. Be careful with the Acid levels, the temperature (always between 24-25º C) and feed them correctly.
We will create some more ecosystems.
