The Five Senses

Do you hear that? What is that smell? Let me see that. What is that taste? Do you feel that? Although we may use these questions quite often, it may be hard to define what each sense is. You use your sight, hearing, tasting, touching and smelling senses everyday. They are so common that one doesn't even know they are doing it. 




What Are the Five Senses? 

Our senses allow us to experience the world around us.The senses allow us to see, hear, smell, taste and touch things. Each sense is associated with a specific sensory organ.
  • The eyes give us the sense of sight.
  • The ears give us the sense of hearing.
  • The nose gives us the sense of smell.
  • The tongue gives us the sense of taste.
  • The skin gives us the sense of touch.

The eyes and sight

Your eyes give you the sense of sight. This sense is normally the one that we use the most as it allows us to see. Your eyes capture light and converts it into images for the brain to process. Sight allows us to see the size, form, color, and location of things that are around us or in our environment.
To take care of our eyes we should read in good natural light and avoid spending too much time in front of a screen.

The ears and hearing

Your ears give you the sense of hearing. This sense allows us to hear or listen to sounds that are around us. You can hear music and listen to people talking because of your sense of hearing.
To take care of our ears we should listen to music at moderate levels and avoid inserting objects into the ear which may damage it.

The nose and the sense of smell

Your nose gives you the sense of smell. This sense allows us to smell and distinguish the different aromas (or smells) that things have. The smell of a rose is pleasant. The smell of garbage is stinky.
To take care of our nose we should keep it clean as this helps us breathe better and to perceive different smells better. Do not insert objects into the nose that may damage it.

The tongue and the sense of taste

Your tongue gives you the sense of taste. This sense allows us to perceive the flavor of the things we eat or drink and allows us to identify if it has a sweet, sour, salty, or bitter taste.
To take care of your tongue, it is important to have correct hygiene inside the mouth with includes brushing your teeth regularly.

The skin and touch

Your skin gives you the sense of touch. This sense allows us to feel how something is and know its texture (smooth or rough), it’s hardness (soft or hard) and its temperature (hot or cold) when we touch it.
The skin is a thin layer that covers and protects our body. Did you know that our skin is the largest organ of our body?
To protect our skin, it is important to use sunblock when we are outside and to wash ourselves every day.


Levels of Organization

Definitions of each of the levels of organization in the human body are a click away...




Living Things

Living organisms share characteristics such as the ability to move and reproduce. There are different types of living organisms including plants, animals, fungi, or bacteria.

Living Things Classification

Biological classification works a bit like the library does. Inside the library, books are divided up into certain areas: mistery, science fiction, adventure, drama, comedy... Within each of those sections, there will be more divisions like fiction, non-fiction…

Biological classification works the same way. At the top there are the kingdoms. The kingdoms divide up life into big groups like plants and animals. Under the kingdoms are more divisions until, finally, you get to the species, which is like getting to the book you are searching in the library. 


There are seven levels of classification: Kingdom, Phylum, Class, Order, Family, Genus, and Species. The two main kingdoms we think about are plants and animals.




Here is an example of how humans are classified:

Kingdom: Animalia 
Phylum: Chordata 
Class: Mammalia 
Order: Primates 
Family: Hominidae 
Genus: Homo 
Species: Homo sapiens

Cells

Animals and plants are made of cells. Cells form the basic "building blocks" for living things. 

Cells are very small. They are the basic building blocks of all animals and plants. This photograph shows cells seen through a microscope:

Eclipses and Tides

What is an eclipse?

An eclipse occurs when one object in space blocks an observer from seeing another object in space. From Earth there are two main types of eclipses: solar eclipses and lunar eclipses.

What is a Solar Eclipse?

A solar eclipse occurs when the Moon passes in front of the Sun causing a shadow to fall on certain portions of the Earth. The eclipse is not seen from every place on Earth, but only from the locations where the shadow falls. From these locations, it appears as if the Sun has gone dark.


  • There is a portion of the Moon's shadow where the Moon completely covers the sun (total eclipse). This is called Umbra.
  • The area of the shadow where only a portion of the Moon (partial eclipse) is in front of the Sun is called Penumbra.

Never look directly at a solar eclipse! Even though it appears darker, the rays of the Sun can still damage your eyes...


Lunar Eclipse:

A lunar eclipse occurs when the Moon passes through the Earth's shadow. Lunar eclipses have the same three phases or types as solar eclipses including the umbra (total), antumbra (annular), and penumbra (partial). 



Lunar eclipses can be seen by a much larger area of the Earth than solar eclipses. They also can be watched without special equipment to protect the eyes. Lunar eclipses are not totally dark. The Moon will reflect some sunlight that is refracted by the Earth's atmosphere. The light that is refracted is reddish, and the Moon looks like a red planet like Mars.


Now watch the vid where we can witness what is to be like in a place where a total solar eclipse occurs as it did in Madras, Oregon on August 21, 2017



Ocean’s tides are explained in this video: How the tides work? Why the oceans experience two high tides and two low tides each day?


Homophones & Homographs


Homophones are words that are pronounced the same, usually spelled differently, and have different meanings.

Here are some examples of homophones:

-Ark (boat), Arc (part of a circle)

-Bank (the side of a river), Bank (a place to keep money)
-Hare (rabbit), Hair (grows on the human head)
