Homework 26th January

Arrange the pieces of the senses so as to make a mind map like this one:

 

Summary: The senses

Summary: The sense of sight

 You use sight to distinguish the shape, colour and size of the objects and how far they are (distance).

The eyes are the organs of sight and they are protected by the eyelids, the eyelashes and the eyebrows.

The light passes through the cornea and through the pupil in the iris .The light comes to the lens and then to the retina that sends the information through the optic nerve to the brain.

Summary: The sense of hearing

The ears are the organs of hearing. They have three parts: outer ear (pinna), middle ear (ear canal) and inner ear.

The inner ear has three parts: eardrum, small bones and cochlea.

The sounds make the eardrum vibrate and those vibrations pass to the small bones and to the cochlea. The cochlea turns these vibrations into information that is sent through the auditory nerve to the brain.

Summary: The sense of touch

First you have to get an object to touch it. We can feel if it is smooth or rough; hot or cold; painful or agreeable with the skin. The skin is the organ of the sense of touch and there are the touch receptors that send the information through the nerves to the brain.

Summary: The sense of smell

The smell goes inside the nose through the nostrils, then reaches the olfactory epithelium inside the nasal cavity. Smell receptors in the epithelium send the information to the olfactory bulb in the brain.

Summary: The sense of taste

We use the sense of taste to distinguish flavours: sweet, salty, sour, bitter and umami. The tongue is the organ of the sense of taste and is covered with the taste buds that send the information through the nerves to the brain.

Sergio´s homework

Hello 3rd graders!

I remind you that today you have Natural Sciences homework. You must draw a big eye (at the back of the paper of yesterday´s questions) and label the main parts of the eye (like the picture in page 20 of the book).

Besides, tomorrow in 3A and on Friday in 3B we will make a summary of page 20 (the sense of sight and the eye). You can read the text and try to explain orally to your parents how does the sight work so as to advance a little bit more on this (3B already did this in class today but they can do it again at home anyway).

Finally, these are the answers to the questions in page 19 that we corrected this morning:

Who uses sign language and why?

Deaf people uses sign language, because they can´t hear.

Which sense is used to interpret sign language?

Sight is used to interpret sign language

What do the gestures and signs represent?

They represent words and sentences

How many sign languages are there?

There are a lot of sign languages

What is the policeman doing in the picture?

He is making the car and the motorbike stop

Best regards,

Cristina
