SCIENCE UNIT: MATTER, MATERIALS AND FORCES

SCIENCE UNIT

UNIT 7: MATTER AND MATERIALS

During the next weeks we are going to study about matter and materials. We are going to learn about the importance of recycling and also about how matter can change. Mixing and separeting materials is very interesting, and we are going to check on this, too. 

LOOK AT THESE VIDEOS AND PRACTICE THE CONTENTS THAT WE STUDY IN CLASS.

WHAT IS MATTER? 

REMEMBER THAT MATTER IS EVERYTHING WE CAN SEE, OR TOUCH, OR SMELL, OR TASTE. ACTUALLY, EVERYTHING ON THE PLANET IS MADE UP OF MATTER,  AND YOU ARE ALSO  MADE UP OF MATTER!!

PHYSICAL AND CHEMICAL CHANGES OF MATTER

PHYSICAL CHANGES: CHANGES OF MATTER

We know that mixtures have two or more materials and that sometimes we can see the different materials but others we cannot see the different materials. but, can we separate the components of a mixture? Yes!
Look at these videos to learn how.

sieving: when we want to separate solids of different sizes.

FILTERING: to separate solids from a liquid.

EVAPORATING: to separate a solid that is dissolved in a liquid.

NATURAL AND MANUFACTURED MATERIALS

WELCOME TO 3rd GRADE!

WELCOME TO 3rd GRADE!
Do you like science? I love science! This year we are going to learn a lot of interesting things about science at school. Are you ready? Let´s go!

¡BIENVENIDOS A 3º!
¿Te gustan las ciencias? ¡A mi me encantan! Este curso vamos a aprender en el cole muchas cosas interesantes sobre las ciencias. ¿Estás preparado? ¡Vamos!

                                                           THE PLANT KINGDOM

We studied people share the planet with animals, but we share our world with plants too. They are living things because they are born, grow, reproduce and die. A plant has different parts and we can find three types of plants: trees, bushes and grasses. We use plants in different ways; we eat them, we get oxygen to live, we get fabrics...
Plants are very good friends of us!

                                                ¡AQUÍ ENCAJAMOS TODOS!

Hoy es día 2 de abril y vamos a celebrar el día del autismo. 
A veces nos vamos a encontrar con niños o niñas un poco diferentes a los demás. Son chicos y chicas a los que les cuesta comunicarse, les molestan los ruidos o tienen una conducta diferente porque viven en su propia realidad y les resulta muy difícil abrirse al mundo. Muchos/as saben un montón sobre algunos temas y, si por ellos o ellas fuera, siempre estudiarían o aprenderían sobre ello.
En el colegio tenemos un aula especial para estos chicos y chicas. Se llama el Aula Arco Iris. Allí aprenden a abrirse al mundo, pero nos necesitan a nosotros/as para entender que no están solos/as.
Hagamos lo posible para ser sus amigos o amigas porque también los demás podemos aprender con  ellos y ellas...¡una barbaridad! Quizás así entendamos mejor que en nuestro mundo no sobra nadie porque...¡AQUÍ ENCAJAMOS TODOS!... Exactamente igual que las piezas de un puzzle.

                                                                       THE ANIMAL KINGDOM

People share the planet with animals. Depending on their special characteristics, there are different types of animals: mammals, birds, reptiles, amphibians, fish, arthropods and molluscs.
They must be our friends and we must look after them.

 

                                                            MACHINES AND ENERGY

Machines are very important for us.They are everywhere and they help us making our lives easier.

Depending on how many parts they have, they can be simple or complex.

Machines can work with a force (pull push, turn, switch...) or with energy from batteries or electricity.

They are good for people but we need to be careful because they can be dangerous, too.

Some machines use the wind, the heat from the sun and the water to provide energy for people (renewable energies). They are also good for the environment)

                                                                    MATTER ,FORCES AND ENERGY

We see materials everywhere. There  are different types of materials. They can be smooth, rough, soft, hard, transparent, opaque, flexible, rigid, rtc.
We can separate materials to see their components. Some materials can change, others cannot change.
We can bend, stretch or squeeze materials using a force. With a force we can push or pull materials.
