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.

Getting ready the Acuarium at school.

We had to leave ready our acuarium these days and feed automatically the fish.

That’s why some of our sessions have been by the acuarium

  • We cleaned the tank.
  • We supervised the temperature. 25° C.
  • We cleaned the filter. Cleaning all the different layers of filtering sponges and rocks.
  • We planted some plants.
  • We have programmed correctly the light hours.
  • And the most important thing is to leave the automatic dispenser of food ready to feed the fish twice a day.

Here you can see some of this process and care our  animals need.

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.

INTRODUCING NEW FISH IN OUR ACUARIUM

Yesterday the children of 4ºA could experience how to introduce and perform this process to get and add new tropical fish in our school tank.
The steps we did we did were the following
1) Turn off the lights in the aquarium; bright light may disturb the new fish.

2) Float the bags containing the new fish in the aquarium. If they have travelled for more than 20 minutes then open the bags to allow air in. The sides of the bags can be rolled down to create a ‘floating rim’, keeping the bag upright.

3) After about 15-20 minutes the temperature of the water in the bag should have equalised to that of the aquarium water.
4) Before introucing the fish it’s neccessary to add two or three glasses of water into the plastic bag to balance the water levels into the plastic bags. Now the fish can have the similar conditions. The fish can now be gently released from the bag by slowly tipping into the aquarium.

4) Leave the aquarium lights off for another few hours or for the rest of the day, in most cases the new fish will not need to be fed and may be unwilling to feed but it may be wise to feed the existing fish to divert their attentions away from the new fish.

We show you some of this process in the photos.
