FORCES: push and pull; contact and non-contact; gravity and magnetism; weight; upthrust

 This term we have begun learning about forces. There are two basic forces that make things move or stand still.

These are 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). However, weight is a force that depends on the mass an object has and we measure it in newtons (N). It may be a little bit complicated so I hope this simple video will help you to see the difference.

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. 

ROCKS

 In Social Science we continue learning about rocks.

Before talking about rocks I'd like you to review something you learnt in 2nd grade: THE LAYERS OF THE EARTH.

Some of these layers are closely related to rocks: the crust and the mantle. 

Here you have a video by Dr Binocs  that has become a friend of ours in the class.

We all know that there are different types of rocks. 

In the next video, you will understand the CLASSIFICATION OF ROCKS.

 Hope you enjoy it!!!

MATTER AND ITS PROPERTIES

 In Natural Science we are learning about MATTER.

We already know that matter is everything around us, that is, everything around us is made of matter.

Matter has some properties that define it: volume, mass and density.

We can measure volume (㎤), mass (g) and density (g/㎤).

 Matter can be in any of the three states we know: solid, liquid or gas.

Watch these videos and find out more!!!

In this last video you can sing and have fun with the Measuring Matter Song

MINERALS

 In Social Science we are learning many things about minerals and rocks. 

I have chosen several videos I know you are going to enjoy.

In the following two videos you are going to learn and understand the definition of mineral.

In the next video, you can visit the Canadian Museum of Nature and appreciate some really marvellous minerals.

Diamonds are the hardest minerals on Earth. So here you have a special video that shows you their characteristics and properties.

In this last video you can learn about the different uses of rocks and minerals.

FOTOS PARA EL RECUERDO DEL CARNAVAL 2021

 Aquí os dejamos algunas de las fotos de los profes y los alumnos de 4º para que tengáis de recuerdo.

Pasamos un día estupendo y fue muy divertido ir todos disfrazados y poder disfrutar de nuevo de los dragones y cabezudos y de la sardina que llevaban como siempre los alumnos y alumnas de 6º. 

Carnaval 2021

HEALTH AND MEDICINE

In Natural Science we are becoming familiar with  medicine discoveries to help people not to get ill or to cure them once they are ill.

Though there are many scientists and many discoveries, we are going to see some general ideas through some easy videos.

 I hope you like them and you learn a little bit more apart from the contents in your book.

We all know that vaccines are necessary and help us prevent very serious illnesses caused by virus. The first vaccine was discovered in 1796 by Edward Jenner. Here you have two videos in connection with the origin of vaccines and how they work.

We are also learning a little bit about antibiotics that help us cure infections caused by bacteria.

The first antibiotic to be discovered was penicillin. Penicillin was discovered not so long ago, in 1928, by Alexander Fleming.

In the first video you are going to find out a little bit about Alexander Fleming and his discovery. In the second video you will learn something about how antibiotics work.

STORY TIME: WHY DO DOGS SNIFF BOTTOMS?

Good afternoon everybody!!! 

I hope you are alright on Thursday 14th of January, a sunny cold day.

A few days ago I read this story with Rachel and I found it very funny and as I know most of you love dogs I think it's good sharing it.

You'll let me know if you like it or not.

Have a wonderful day and BE HAPPY!!!!
