ÁREA/ MATERIA Natural Science

NÚCLEO TEMÁTICO Bloque I: La vida en acción

GUÍON TEMÁTICO

Animales y plantas recibimos gran cantidad de información

del medio exterior en forma de olores, sonidos, imágenes o cambios de temperatura, y también del interior del organismo, como el hambre, la sed, el cansancio o el dolor.

Cada animal responde de forma distinta a los cambios que percibe y ha realizado unas adaptaciones concretas para sobrevivir.

“Stimulus”

1.- Copy on your notebook:

Stimuli Definition: “It is any factor that is able to cause a reaction on a living being”

Use your text book to complete the following information:

According to its origin:

Internal

External

According to its proprieties:

Physical

Types of STIMULUS


http://www.bbc.co.uk/science/humanbody/body/interactives/senseschallenge/senses.swf

2.- Classify the following stimulus among internal and external, and physical or

chemical:

Tiredness

Bad smell

Stress

Speed

Sleep

To wet oneself

To feel ear pressure

Temperature

Light and darkness

Flavours

Body contact

Balance

3.- Discuss your results with your partner.

4.- Share the results with the whole class. Let´s write them on the board, creating a table

as it follows. Discuss and correct the results with the rest of the class. Copy the final

table on your notebook.

Stimulus Internal External

Physical

Chemical


“Stimulus receptors”

1.- Copy on your note book:

Receptor Definition: “They are cells specialized in picking up stimulus, whether they

are internal or external, and send them to the brain through the nervous system”.

Depending on the stimulus, we can distinguish several types of receptors:

Mechanoreceptor: It responds to mechanical pressure.

Chemoreceptor: It detects certain chemical stimuli.

Photoreceptor: It detects light and darkness

Termorreceptores: It responds to temperature changes

Electrorreceptores: It detects Detectan la Electricidad

“sense organs”

1.- Describe what you see. Then pay attention to your teacher explanations:

1.- Sight

Types of Receptors


2.- Hearing


3.- Smell


4.- Taste

5.- Touch


3.- Look into the internet to explain the following ideas. Use the scroll to write down

your research.

Lateral line in fishes:

Compound eyes in flies:


4.- Watch the video “Human senses” from the BBC.

www.youtube.com/watch?v=UKxTq38Hd0c

5.- Make groups of four and choose a leader. Then, answer the following questions

about the video and write the answers in your notebook.

SIGHT

Why do some people need glasses? How do glasses improve vision?

What causes nearsightedness? How is it different from farsightedness?

How does corrective laser eye surgery work? How does it improve vision? What

risks are involved?

How do optical illusions work? How do they "fool" your brain?

How do red-and-blue "3D glasses" work?

HEARING

How do sounds reach the brain?

Why do some sounds have a low pitch, while others have a high pitch?

Why are animals such as dogs able to hear sounds that humans cannot?

When someone is "hard of hearing," what are some possible causes?

SMELL

Why do certain smells instantly evoke specific memories or feelings?

How are the senses of smell and taste related?

If you hold your nose while eating, how are tastes affected? Why?

TASTE

How do taste buds work? How does the tongue recognize different tastes, such as

the bitterness of a lemon or the sweetness of sugar?

Which taste cannot be detected by the tip of your tongue: bitter, sour, salty, or

sweet? Why?

TOUCH

How does your hand tell the difference between hot and cold surfaces?

How do blind people use braille to read?

6.- Describe what you can..

7.- Discuss your results with your partner.

8.- Read the information about the different senses and complete the text with the words

from the box

HEARING

Not all sounds are normally audible to all animals. Each species has a range of normal

hearing for both loudness (amplitude) and pitch (frequency). Many animals use

_________ to communicate with each other, and ________in these species is

particularly important for survival and reproduction. In species that use sound as a

primary means of_______________, hearing is typically most acute for the range of

pitches produced in calls and speech.

Frequencies capable of being heard by humans are called audio or sonic. The range is

typically considered to be between 20 Hz and 20,000 Hz. Frequencies higher than audio

are referred to as____________, while frequencies below audio are referred to

as___________. Some bats use ultrasound for echolocation while in flight. Dogs are

able to hear ultrasound, which is the principle of 'silent' dog whistles. Snakes sense


infrasound through their bellies, and whales, giraffes, dolphins and elephants use it for

communication.

SIGHT

The visual system in humans and animals allows individuals to ____________

information from the environment. The act of seeing starts when the lens of the eye

focuses an image of its _____________ onto a light-sensitive membrane in the back of

the eye, called the retina. The retina is actually part of the brain that is isolated to serve

as a transducer for the _____________ of patterns of light into neuronal signals. The

lens of the eye focuses light on the photoreceptive cells of the retina, which detect the

photons of light and _____________ by producing neural impulses. These signals are

__________ in a hierarchical fashion by different parts of the brain, from the retina

upstream to central ganglia in the brain.

respond Assimilate surroundings conversion processed

TASTE

Taste is one of the traditional five senses. It refers to the ability to _________ the

flavour of substances such as food, certain minerals, poisons, etc.

Humans ____________ tastes through sensory organs called taste buds, or gustatory

calyculi, concentrated on the top of the tongue. Taste is sensed through taste cell, which

are known as taste buds. There are about 100,000 taste buds that are _________ on the

back and front of the tongue. Others are located on the roof, sides and back of the

mouth, and in the throat. The sensation of taste can be categorized into five basic tastes:

sweet, bitter, sour, salty, and umami. “Umami” is originally the Japanese word for

“meaty” or “savory”. Not surprisingly, it is characteristic of many oriental dishes.

The basic tastes ____________ only partially to the sensation and flavour of food in the

mouth. Other factors _____________ smell, detected by the olfactory epithelium of the

nose; texture, detected through a variety of mechanoreceptors, muscle nerves, etc.;

temperature, detected by thermoreceptors.

Detect contribute include receive located

TOUCH

The sensory receptors cover the skin and epithelia, skeletal muscles, bones and joints,

internal organs, and the cardiovascular system. While touch is ____________ one of the

five traditional senses, the impression of touch is __________ from several modalities.

In medicine, the colloquial term touch is usually ___________ with somatic senses to

better reflect the variety of mechanisms involved.

Sound hearing communication ultrasonic infrasonic


The system reacts to diverse stimuli using different receptors: thermoreceptors,

nociceptors, mechanoreceptors and chemoreceptors.

formed Considered replaced

SMELL

Olfaction is the sense of smell. This __________ is mediated by specialized sensory

cells of the nasal cavity of vertebrates, and, by analogy, sensory cells of the antennae

of_______________ . Many _______________, including most mammals and reptiles,

have two distinct olfactory systems—the main olfactory system, and the accessory

olfactory system (used mainly to detect pheromones). Olfaction, along with ________,

is a form of chemoreception. The chemicals themselves that activate the olfactory

system, in general at very low__________________, are called odorants.

Concentrations taste sense vertebrates invertebrates
