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!




WATCHING ANAGLYPH IMAGES WITH 3D Glasses

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!

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!
