What is growing on that disk?

Today in our Science class we have studied the fouling of our Virtue disks using even stereo microscopes. Andrea and Judit, 1st ESO students have come to help us to identify organisms and we could draw the results on ipads.
Andrea has had the virtue rack placed for five months in Roses.
We saw living “mantis shrimps”, algaes and many other organisms.
It was really interesting!
Have a look at the pics!





Look this is a grown up mantis shrimp, ours are very tiny!

DOES AN ORANGE FLOAT OR SINK?

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!


TOOTHPICKS!

Today we’ve been playing with toothpicks to test the surface tension of coloured water. We’ve found out that dipping a soapy toothpick into the water could break the surface tension and our toothpick stars! Have a look at our pictures!



IT’S STORYTIME: DIARY OF A WOMBAT

What exactly do wombats all day?
Wombats are cuddly-looking slow moving Australian animals. Their favourite activities are eating, sleeping and digging holes.
In our Science class we’ve been listening to the story: DIARY OF A WOMBAT
We’ve had so much fun!

SOIL ANALYSIS FOR PROJECT POLAR BEAR

Today the teams Eco Scientists 1&2 have determined different characteristics of our vegetable gardens in K4 and Grade 4 such as temperature, soil moisture, acidity or pH –level.

Also, they have started to record the size of the plants and their leaves to determine the expected growth and they’ve had a look at our Californian worms and how the vermicomposting is going.




TODAY IS MONDAY

Today we’ve listened to the song ‘Today is Monday’ and we’ve watched the cartoon, too. The catchy tune of this children song gets new life in the picture book and story by Eric Carle. We have had a lot of fun!
