El Ártico se derrite

This year we also learnt things about the Arctic

Pepa Pig ;)

Dissection of a Pig´s Heart, Lungs, and Kidney

The students went to the laboratory to observe various pig organs. They reviewed the pathway of air through the trachea and into the lungs, the route blood takes through the heart and the heart´s different muscles, and the structures of a kidney, all first hand. They also were able to hold and cut into their own organs to better understand the anatomy of a pig, the animal which is most similar to humans anatomically.

Bye bye Molly with 3º ESO

Today was the last day with Molly :(

Separation of Plant Pigments Using Chromatography

Is a method to identify plant pigments by separation and isolation of the pigments using thin layer paper chromatography.


If you wan to see again the protocol used just click on the following direction:

at the end we obtained our chromatography

Water cycle

We was studing the water cycle!

To carry out this experimet we just needed a bag, water, a pen and some dye!

If you put the bag in a window, with the temperature of the sun, we can study the evaporation and the condensation of the water.

If you put the bag into the freezer you can study the transformation from liquid to solid (Freezing), and if you put the bag out to the freezer againg, you´ll study the  melting!

Cornstarch experiment

Cornstarch Experiment: Suspension Phase

               

                In this experiment our students mixed cornstarch with water and observed the unique properties of the resulting mixture. They saw that the mix was fluid and acted like a liquid when it was left alone or poured slowly, but displayed properties of solids when force was applied to it. They learned that this was because cornstarch and water combine to form a suspension, which is a state that changes viscocity with differing levels of force, instead of different temperatures. It´s a non-Newtonian liquid.
