HERE COMES THE SUN (GEORGE HARRISON, THE BEATLES)

Here comes the sun, doo-doo-doo-doo

Here comes the sun, and I say

It's alright

Little darlin', it's been a long, cold, lonely winter

Little darlin', it feels like years since it's been here

Here comes the sun, doo-doo-doo-doo

Here comes the sun, and I say

It's alright

Little darlin', the smile's returning to their faces

Little darlin', it seems like years since it's been here

Here comes the sun

Here comes the sun, and I say

It's alright

Sun, sun, sun, here it comes

Little darlin', I feel that ice is slowly melting

Little darlin', it seems like years since it's been clear

Here comes the sun, doo-doo-doo-doo

Here comes the sun, and I say

It's alright

Here comes the sun, doo-doo-doo-doo

Here comes the sun

It's alright

THE INVENTION OF THE TELEGRAPH BY SAMUEL MORSE

The telegraph is a device for communicating over a distance. It uses electricity to send coded messages through wires. In the middle of the 1800s the telegraph was the fastest way to communicate over long distances.

An American artist and inventor named Samuel F.B. Morse created Morse Code in the 1830s. Before his invention, an important message could take weeks to reach its destination.

Morse Code and the telegraph allowed people to receive information sent from far away in just minutes. Newspapers, railroads, and businesses used the code and the telegraph to send news quickly from one city to another.

Morse Code uses dots, dashes, and spaces to represent letters, punctuation, and numbers. The symbols are arranged to spell out a message. A telegraph converts the symbols into electrical signals and sends them across a wire to their destination. The signals are then converted back into the message by the telegraph that receives them.

Here you have a video that explains the invention of the Morse Code.

ANCIENTE HISTORY ON THE IBERIAN PENINSULA

We are almost ending the school year and in Social Science we are learning History. To be precise we are learning about the things than happened here on the Iberian Peninsula.

We all know that we were Celtiberians but apart from that we have met the different people that came to the peninsula like the Greeks, the Phoenicians and the Carthaginians.

In the following video you can remember the differences between all the people living here thousands of years ago.

As the Celts were very good metal workers and warriors, many other people came to look for metals but some came also to trade and they decided to stay and form some colonies. The next video explains very well who those people were and where they came from.

The last of these people to come were the Romans but they came to stay and we began to be part of the Roman Empire. The following video explains very nicely how this happened. The Roman Conquest of Hispania

And finally, to understand this huge empire, the Roman Empire, I invite you to watch the following video about them.

I hope all these videos help you understand and learn our Social Science last lesson!!!

FORCES: PUSH AND PULL; CONTACT AND NON-CONTACT; MAGNETISM; GRAVITY, WEIGHT AND UPTHRUST

This term we have begun learning about FORCES.

There are two basic forces that make things move or stand still: PUSH and PULL.

Here you have a very simple video that explains them easily.

We have also learnt that there are two types of forces: CONTACT and NON-CONTACT forces. In the following video you can learn more about forces, work and energy with the help of Dr Binocs.

We have also studied two non-contact forces: GRAVITY and MAGNETISM.

Magnets are objects that attract or repel other objects that contain iron or steel. Here you have another video by Dr Binocs explaining magnetism

Gravity is a pull force noticeable with very large objects such as planets. Watch the following video to learn more.

The first person to talk about this force was Isaac Newton, a scientist and mathematician that explained many laws in Nature. Here you have a video about him.

Gravity is related to mass and weight.

We already know that mass is the amount of matter in an object and we measure it in kilograms (kg) or grams (g). But weight is a force that depends on the mass an object has and also on gravity. Here is the formula:

Weight = mass x gravity

We measure weight in newtons (N).

I hope this simple video will help you to understand these concepts.

Finally, we are going to talk about a contact force applied by water and air: UPTHRUST. This force pushes objects in air and water up. So it is opposite to gravity.

The upthrust depends on the mass and the volume the object has that is why some objects float and some others sink.

An ancient Greek scientist called Archimedes discovered this upthrust force more than 2,000 years ago while having a bath. Here you have a video that explains this easily.
