ZOOPLANKTON PROJECT: Hatching Brine Shrimp Eggs

At the beginning of November we prepared a sea salt solution and we put two table spoons of brine shrimp cysts into it. Brine shrimps are also called artemias or sea monkeys.
The eggs hatched around 3 days later. Constant aeration was also needed. We will keep you updated about our babies!



We put a paper clip on the edge of another paper clip and lowered it gently into a bowl of water. It didn’t sink because surface tension held it afloat. That’s why so many insects are able to walk on water.

How cool!

Message in a bottle & Sea change Project

A message in a bottle has arrived today! The bottle will be among us during one week!

We are participating in a nationwide event called MENSAJE EN UNA BOTELLA to raise eco awareness. (www.mensajeenunabotella.info)

In Science K4 and K5 we are making our own jellyfish out of plastic bottles during next week.

But what exactly is this project about?

You can find more info here: mensajeenunabotella.info

During September, October, and November 2017 different bottles of recycled material will travel around Spain with an interesting story inside and a big challenge related to ocean issues. This big challenge can be reached by carrying out smaller challenges that will be available on the event website. The different bottles’ routes will start in different points of Spain, specifically in aquariums that will receive these bottles with a parchment inside. The first participants will pick up the bottles at these points, starting each of the routes across Spain.

The aim is to raise awareness that our actions (both in coastal areas and inland areas) affect the marine environment.

In July we went to the beach to meet two divers from the L’Aquarium of Barcelona and together we recorded this short video, please have a look!


Does an orange float or sink in water? We began by filling a large bowl of water and placing an orange in the water. The K4 kids discovered that the orange floats. Then we peeled the orange, removing the rind. Next we placed the unpeeled orange in the water and guess what? It started to sink!
The rind of an orange is full of tiny air pockets making it float on the surface!

ZOOPLANKTON PROJECT:Hatching Brine Shrimp Eggs

This week we’ve prepared a salt solution and we’ve put two table spoons of brine shrimp cysts into it.
Brine shrimps are also called artemias or sea monkeys.

The eggs should hatch in 48-72 hours. Constant aeration is also needed.
We will keep you updated about our babies!


In Science we are learning that plankton can be plant-like organisms, called phytoplankton, or animal-like, called zooplankton.

Our zooplankton is quite large and we are able to observe it without magnifying glasses.

Have a look at the pictures! We are observing artemias here!


In our Science class we have been watching anaglyph images!
We have used special red/cyan 3D glasses in order to observe different planets of our solarsystem, images of the moon and many others.
We even have watched some 3D videoclips and have taken a ride on a virtual reality roller coaster. Have a look, we have had so much fun!
