SENSES AND BRAIN ARE CONNECTED

All your senses are connected to the brain with nerves.
After receiving the information the BRAIN decides the best response.
The NERVOUS SYSTEM connects your senses with your brain.

TOUCH SMELL AND TASTE

TOUCH, SMELL AND TASTE

We use the sense of touch to identity characteristics of objects.

Objects can be:

·         Rough.

·         Smooth.

·         Hot.

·         Cold

We can distinguish between agreeable and painful sensations.

The skin is the sense organ of touch.

The body is covered with skin.

In your skin there are touch receptors that send information to the brain.

Sensitive parts of your body (lips, fingertips…) have more touch receptors.

The sense organ of the SMELL is the nose.

SMELLS enter  the nose through the NOSTRILS.

SMELLS  reach the OLFACTORY EPITHELIUM  in the NASAL CAVITY

SMELL RECEPTORS are located in the OLFACTORY EPITHELIUM.

SMELL RECEPTORS send signals to the OLFACTORY BULB

↓↓↓↓↓↓

OLFACTORY BULB is in the brain

copy the diagram from page 22and write the names of the

 different parts, then glue it in your notebook

3ºB15-11-18

The sense of TASTE is located in the tongue.

The TONGUE is covered with small bumps called TASTE BUDS.

Thre are specific TASTE BUDS located in different areas of the tongue to distinguish 

different flavours.

SENSITIVITY

1. COPY THIS MINDMAP IN YOUR NOTEBOOK.
2. TRY TO EXPLAIN THE PROCESS OF SENSITIVITY TO YOUR SOMEONE: FAMILY OR FRIEND.

READ PAGE 13 BEFORE THURSDAY

In the following video you can see the process of nutrition. Remember the four stages and the four systems involved in this process (pages 12 and 13.).

Notebook work related to pages 12 and 13.

Explain the process of nutrition: ………………………………………….

COPY THE BROWN BOX

The stages of nutrition:

1. 1.       DIGESTION: absortion of nutrients from food    
2. 2.       RESPIRATION: we breath in air to obtain oxygen.
3. 3.       CIRCULATION: nutrients and oxygen travel throughout human body
4. 4.       EXCRETION: expel waste material.

COPY THE BROWN BOX

Systems involved in nutrition:

Using the book explain each one of the systems.

1. 1.       THE DIGESTIVE SYSTEM:
2. 2.       THE CIRCULATORY SYSTEM:
3. 3.       THE RESPIRATORY SYSTEM:
4. 4.       THE EXCRETORY SYSTEM:

Bienvenida.

Estimados alumnos y familias, en este blog iré colgando información interesante relacionada con los temas de science que estamos trabajando.
También incluiré entradas con los trabajos que realizamos en el cuaderno de clase, para que  podais ir aprendiendo a  hacer esquemas y resúmenes de los temas.

Intento que la clase de Science cuente con la participación de los alumnos, y que no vayan solamente a escuchar. Para eso es necesario leer los resúmenes y conocer el vocabulario antes de la explicación.


Espero que esta iniciativa nos ayude  a todos a mejorar y que el trabajo que tenemos por delante este curso salga lo mejor posible.


¡¡¡Animo!!!
