FORCES IN MATTER

Forces can act from a distance o through contact. When they act from a distance they are cold non-contact forces. When they come into contact with the object they are called contact forces.

NON-CONTACT FORCES

Magnetism is a force that can attract or repel mangetic objetcs. Let's watch the following video.

Gravity is a non-contact force that pulls objects towards  each other.

CONTACT FORCES

We have got  two different contact forces: Applied force and Buoyant force.

When an object is put in a liquid there is an upward force acting on it called buoyancy. This is what makes objects float.

Watch the following videos about this force:

CHANGES IN MATTER

Matter can change in many ways. These changes are classified into two types:

Physical changes and Chemical changes.

PHYSICAL CHANGES

In a physical change no new substance is formed and properties of the substance stay the same.

CHEMICAL CHANGES

In a chemical change a new substance or substances form.

PHYSICAL PROPERTIES OF MATTER

Matter is everything that exists. All living things and non-living things are made of matter.

Let's learn more things about Matter watching the following videos:

Sources of Energy (Non-renewable and renewable energy)

There are two types sources of energy :renewable and non-renewable resources. 

Non-renewable energy sources come from the ground and the seabed. We can't replace these natural materials and they will eventuallu run out.

Renewable energy: we can also find the Sun, wind and water as sources of energy. These are renewable sources of energy because they do not run out. They are much better for the environment because they do not cause pollution. 

Energy | The Dr. Binocs Show | Educational Videos For Kids

There are many different types of energy. We are going to look at the six most important types.  

1. SOLAR OR THERMAL ENERGY.

2. MECHANICAL ENERGY

3. SOUND ENERGY

4. ELECTRICAL ENERGY

5. LIGHT ENERGY

6. CHEMICAL ENERGY

Now, learn everything about energy in detail with Dr. Binocs.

Forces Lab (Game)

Play this game!: In this lab you can do some actions that affects objects: squeeze, strech bend, slide, and twist. 

Separating Materials in a Mixture: Sieving, Filtering and Evaporating

We can SEPARATE the different materials in a mixture. 
We can separate some materials in a mixture by SIEVING, FILTERING or EVAPORATING. 
- SIEVING: good for separating solids of different sizes. 

- FILTERING: good for separating solids and liquids. 

- EVAPORATING: good for separating a solid that is dissolved in a liquid. 

States of Matter song

This is a song for kids about the 3 states of matter: solid, liquid, and gas. 

Magnets and Springs (Game)

Play with magnets to see how they can move objects. 

Gases around us (Game)

Solids and Liquids (Game)

When we heat or freeze liquids or solids some physical changes are produced. Play this game and learn. 

Reversible and Irreversible Changes (Game)

A mixture is something that contains two or more different materials. In some mixtures we can see the different materials; in other it is impossible to see the different materials. 

Play this game and learn about it. 

Playtime with parachutes: How do they work?

A parachute is a simple machine. They are used for fun and safety. 

So, how do parachutes work to slow down people in the sky, or make a fun bubble to play in?. 

Let's see!.

UNIT 4 YEAR 3: 'The Animal Kingdom'

Estimados padres y madres de alumnos/as de 3º: 


Como sabéis, estamos trabajando con los niños/as la UNIDAD 4 de Natural Science (Ciencias Naturales) sobre el Reino Animal.  Destacamos estos estándares en esta unidad: 

- Consulta y utiliza documentos escritos, imágenes y gráficos.
- Utiliza el vocabulario correspondiente a cada uno de los bloques de contenido.
- Participa en trabajos de equipo realizando la tarea asignada. 
- Utiliza estrategias para realizar trabajos en equipo, mostrando habilidades para la resolución pacífica de conflictos. 
- Diferencia entre animales vertebrados e invertebrados atendiendo a sus características.
- Hace un uso adecuado de las tecnologías de la información y la comunicación como recurso de ocio.
- Selecciona y organiza información concreta y relevante, obteniendo conclusiones y comunicando su experiencia oralmente y por escrito.
- Manifiesta una cierta precisión y  rigor en la observación y en la elaboración de los trabajos correspondientes.

En casa podéis practicar con vuestros hijos/as lo que están aprendiendo en clase visitando el BLOG DEL SELE “CBM Pintor Pedro Cano”: http://cbmceippintorpedrocano.blogspot.com.es/ , accediendo a los apartados de "Let's search" y pinchando en “Natural Science 3 Unit 4” donde encontraréis videos,juegos,canciones, etc vistos en clase, algunos del curso pasado porque se refuerzan y/o repasa lo aprendido y deben seguir haciéndolo para que el aprendizaje sea más efectivo.   

Os animo desde casa a interiorizar estos contenidos en español, preguntando de forma natural características de animales vertebrados e invertebrados, a través del uso de enciclopedias o libros que tengáis en casa, etc. 

Un cordial saludo. 

Insects (Video)

Let's take a closer look at the biggest group of arthropods: insects. All insects have three main sections: a head, a thorax and an abdomen.  

'The Animal Machine' (Game)

Click on everything that belongs to each category. Have a good time with the 'Animals Machine'. 

Invertebrate groups (Videos)

There are many different types of invertebrates and we classify them into groups. 

ARTHROPODS

This group includes four subgroups: insects, arachnids, myriapods and crustaceans.

MOLLUSCS

There are three main subgroups: gastropds, bivalves and cephalopods

OTHER INVERTEBRATE GROUPS

There are other groups of invertebrates that include a variety of different animals: 

CNIDARIANS: such as jellyfish

ANNELIDS: such as earthworms

ECHINODERMS: such as starfish

FISH | Animals for children. Kids videos

Fish are the biggest group of vertebrates. Fish live in fresh water or in the sea. Most fish are oviparous, but sharks, for example, are viviparous.

These are the main physical characteristics: 

Reptiles | Educational Video for Kids

Reptiles are vertebrate animals. Turtles, tortoises, lizards, snakes, crocodiles, and alligators are reptiles. Reptiles spend most of their time on land, but some spend part of their time in water. Reptiles live in all types of habitats, except in extremely cold climates. 

These are the main characteristics:
