Lemon batteries (6th Grade)

Good morning!

Yesterday, we made a watch work with a very special battery: A LEMON!!!

There are many variations of this experiment. You need a piece of COPPER (for example, a 0,05€ coin), a piece of ZINC (for example, a screw or nail), WIRES, an object that needs electricity to work (for example, a LED) and LEMONS (but also grapes, potatoes,...).

Electricity (6th Grade)

Hello everyone!

In 6th grade we have studied ELECTRICITY. Let us show you some of the contents learned:

We know that all objects have electrical charges. Some are positive, PROTONS, and some are negative, ELECTRONS.

Sometimes, the negative charges pass from one object to another. For example:

- By rubbing a pen to a piece of cloth, we pass negative charges from the cloth to the pen.

Now the pen is (negatively) electrically charged. So, it can attract small pieces of paper.

- Or by rubbing a balloon to a piece of cloth, we pass negative charges to the balloon. So, it is attracted to other objects:

This is STATIC ELECTRICITY.

We also know ho to build an electrical circuits. which carries electrical current:

Finally, we can say if some materials are conductors or insulators after adding them into the circuit:

Temporary magnets (6th Grade)

Hello 6th grade!

Here there is a selection of your temporary magnets (Remember: metallic objects that get magnetic properties when they are in direct contact with a magnet).

Beautiful sculptures!!! :)

Scientist of the month: Galileo Galilei

Good afternoon 6th Grade!

Let's meet the April's Scientist of the Month...

GALILEO GALILEI

Galileo Galilei was born on 15th February 1564 in Pisa, Italy. He is considered the Father of Modern Science, for all the discoveries, theories and experiments he made.

He studied Natural Forces and he was the first person to publish his astronomic observations through a telescope. He discovered:

- The Milky Way is made of many stars.
- The moon has got mountains and craters.
- He saw four moons of Jupiter (called the Galilean Moons)
- Sunspots (dark areas of the Sun)
- Planet Venus has light and dark phases.

So, he concluded that THE SUN IS AT THE CENTRE of the Solar System and NOT the Earth.

Unfortunately, the Church didn't like his opinions and arrested him.

Please, don't forget to watch this video about Galileo Galilei:
