Princes, for a while...!

«Take a little care of me! I'm an unlucky little rose»

Even the little, grumpy rose finally understands and respects the Little prince's need to travel and know the world... "To learn a lot", as he himself says...
…And somehow like that, the two of them parted before the trip… The fourth grade kids (2010-2011) wished him to have nice explorations and kept from him "the light in the heart" and from the little rose its scent and its song…

The adaptation and the texts belong to Ms Katerina Lysiova-as do the infinite interventions in the video for the last-minute directions (or, maybe, to "steal" some of our kids' fame?)!

We are recycling our food! We are composting!

So far we had been recycling paper, plastic, aluminium and batteries in our school.

However, we can reduce our rubbish even more!!

With the help of compost...

What is composting?

It is a way of turning our food left-overs into a nice fertiliser!

We "installed" a grid in a corner of our garden.

We can put dry and fresh greens, vegetables, fruit and egg shells there. In some months we will get a nice fertiliser for our garden!

ATTENTION! 

We mustn't put oil, meat, milk, yoghurt or eggs in the compost grid!

...something good for us and the environment...

Tree planting by the kids of the fourth and fifth grades (2010-2011)...
An apricot tree and an almond tree are now growing in our school's garden...
Because learning is not only dates and equations...!

"We're going to plant treeeeees!"

We dug...

...and dug...

...and dug some more...

...boys...

...and girls...

It was hard work...

...but in the end we made it...!

We settled the tree into its new home...

A little extra soil....

...A small present to Mother Nature...!

Hey! One more!

Kepler 22-B: Earth's bigger brother

What belonged to the sphere of science fiction until recently is now a scientific reality. NASA confirmed that Kepler 22-B, an "exoplanet" which is located 600 years of light away from the Earth, might be hosting life.

This is how NASA's artist imagined Kepler 22-B. In fact, noone knows wether the planet has clouds or sea, if it is a rocky or gas planet. It is 2 and a half times bigger than the Earth, located in the "temperate zone" of the solar system, that is in a point where the existence of water in a liquid state is allowed on its surface. It revolves around its star in a distance 15% shorter than that which separates the Earth from the Sun. However, because its sun transmits 25% less light than ours, the conditions are much alike the ones on the Earth. The average temperature on Kepler 22-B is estimated at around 22°C.

Kepler 22-Β is the first planet for which there is confirmation that it could be hosting forms of life. But it's not the only one. NASA is examining data on another 47 possibly inhabitable planets.

Experimenting with heat...

In our last Science class we researched the transfer of heat through waves.
Through an experimental activity, we understood how hot water goes upwards, hile cold water goes downwards.

Mr Steve Spangler performs a similar activity in the following video.
In a rather...impressive way...!

Watch the video here:

and... try it out at home.
The only things needed are a little coloured water, two same bottles and a playing card.

You can find more fascinating experiments on Mr Spangler's channel on youtube:

Volcanoes...strictly for school use!

They are kids and they come up with ideas! All the time! The idea that had settled itself in their minds at that period was to make volcanoes!
They weren't interested in seeing images and videos, the point was that they saw the red lava flowing in front of their eyes!
The day when a student brought from home his mum's...cooking tray to build in it his own volcano, I realised that it couldn't wait any longer...
Venture "Volcano" so begins...

What we needed:

A bottle of orange juice (which was our "volcano") and clay to build its slopes as life-like as possible!

...science time had come...

We put some cooking soda, some water and a little washing-up liquid in a small funnel and into the volcano...but nothing happened!

Something is needed to make the soda foam to create our lava!

What would that be?

Vinegar (with a few drops of red ink to make our lava red)!

...and the result was something like this:

 

This was one of the two volcanoes that was made by the 5th
grade students (school year 2009-2010)
