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:

Stephen Hawking 1942 - 2018

Stephen Hawking, considered one of the world's most brilliant minds, died today at the age of 76.

He was a great scientist, who studied the laws of the universe, especially black holes. He revealed that black holes have a temperature and produce radiation (the Hawking Radiation).

He wrote many popular books to explain complex scientific ideas, for example: A Brief History of Time is a bestseller.

His friends and colleagues from the University of Cambridge paid tribute to Professor Stephen Hawking with the following video:

Scientist of the month: ADA LOVELACE

Hi everyone!

For 6th graders, a new month means a new scientist to discover :)

ADA LOVELACE

Ada Lovelace (originally Augusta Ada Byron) was born on the 10th December 1815 in London. She was a writer and a mathematician. 

She is considered the world's first computer programmer (although computers weren't invented until one hundred years later!!!). 

 In the Science class we have discovered some facts about her interesting life. 

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

Science news: Super-colony of Penguins Discovered in Antarctica

Scientists of the world are very happy because a mega-colony of  Adelie Penguins were discovered on the Antarctica's Danger Islands.

Scientist found more than 1,5 million of these birds and they used a drone to record the following video:

The objective now is to study these penguins and protect them from human activity. 

Magnetism activities (6th Grade)

Hello everyone!

In 6th grade, we are experimenting with magnets. We had some entertaining lessons, in which we could explore the interesting world of magnetism.

We saw, drew and used magnets of different shapes:

We recognized the two different magnetic poles every magnet has, North and South, and we realized that if we put two magnets together, they can ATTRACT or REPEL. Opposite poles attract; the same poles repel.

ATTRACT:

REPEL:

We could also see the magnetic field lines after spreading out some iron fillings onto a paper, which was laid on a bar magnet.

We couldn't avoid playing with the iron fillings for a while... ;)

Magnetism videos (6th Grade)

Hello children!

You can watch the following Magnetism Videos at home, in order to revise what we learned in class:

Energy Videos (6th Grade)

Good afternoon 6th Grade!

We have just started a new unit: ENERGY.

I remember you that in the "6th Grade" section, you can find many videos about this topic, like the following ones:

Hearing and sounds (6th Grade)

Hello children!

In 6th Grade, we are revising the senses. We did a couple of experiments that you can do at home. They're easy, clear and fun.

MATERIALS:

EXPERIMENT 1:                                   EXPERIMENT 2:

              - A wire clothes hanger                                    - A can

                          - 2 strings                                          - A balloon

                    - Some salt / sugar               - Something to make strong noise 

                                                                 (we used a cover pan and a spoon)

EXPERIMENT 1:

- Make noise with the hanger (for example hitting it to a table) and listen.

- Make the same noise again but this time listen through the strings:

 You will hear a strong GONG!

That's because the sound waves can travel through air, liquids and solids. When we listen to the hanger through the strings, we receive this information through a solid. And solids can transmit sounds better than gases:

1- Solids

2- Liquids

3- Air

EXPERIMENT 2:


We built an EAR DRUM with a can and a balloon to understand how it vibrates with sounds:

Bones (6th Grade)

Hello!

Today we want to show you an experiment we did some days ago, when we were learning the Musculoskeletal System.

First, pupils were asked to bring bones in class. Attention! These bones had to be cooked, cleaned and frozen, for our safety work.

We could also see some cartilage.

Ariadna brought an enormous pig bone!

Once we had all the bones (most of them, chicken bones), we classified them into 3 groups:

LONG - SHORT - FLAT

After that, we broke a bone to see what it has inside: THE BONE MARROW; responsible for making blood cells.

Then, we put some bone in a jar full of white vinegar, and we waited for 2 weeks.

What happened to the bones when we opened the jars after 2 weeks?
