Constellations

Constellations are formed of bright stars which appear close to each other on the sky, but are really far apart in space. The shapes you see all depend on your point of view. Many societies saw patterns among the stars with gods and goddesses or stories from  several cultures.

Most of the constellations with which we are familiar come from ancient Greece. But other civilizations created their own patterns in the sky based on stories and people that were important to them.

The constellations are totally imaginary things that poets, farmers and astronomers have made up over the past 6,000 years (and probably even more!). The real purpose for the constellations is to help us tell which stars are which, nothing more. On a really dark night, you can see about 1000 to 1500 stars. Trying to tell which is which is hard. The constellations help by breaking up the sky into more managable bits. They are used as mnemonics, or memory aids. For example, if you spot three bright stars in a row in the winter evening, you might realize, "Oh! That's part of Orion!" Suddenly, the rest of the constellation falls into place and you can declare: "There's Betelgeuse in Orion's left shoulder and Rigel is his foot." And once you recognize Orion, you can remember that Orion's Hunting Dogs are always nearby. Then you might recognize the two bright stars in the upper and lower left of the photograph as Procyon in Canis Minor and Sirius in Canis Major, respectively. 

I like the greek mytology , the mystique animales , history , monsters, heroes, culture and the goddesses  and all this things we can see  in the constellations .

Vertebrates and invertebrates

There are many different types of animals in the world. Many animals are quite similar to each other. Others are quite different. Animals can be classified based on their similarities. Continue on, and learn more about your fellow Earth inhabitants.

My homework about my two topics.

1.Mammals

Mammals are vertebrates. The y live on theirs mothers milk when young.

Most mammals are born from their mother's womb. Young mammals stay with their mother until they lea en to take care ok themselves. 

Analogys

An analogy is a comparison of two pairs of words that have the same relationship. Analogies are typically express  with colons.

Animals oviparous and viviparous

                                                                                                                      The animals that are oviparous they are animals that lay eggs, with little or no other embryonic development within the mother. This is the reproductive method of most fish, amphibians, reptiles, all birds, the monotremes, and most insects, some molluscs and arachnids.                                                     vivipaous vivipary has two different meanings. In animals, it means development of the embryo inside the body of the mother, eventually leading to live birth, as opposed to laying eggs.                          DGM

VERTEBRATES AND INVERTEBRATES

Invertebrates are animal species that do not possess or develop a vertebral column, derived from the notochord. Familiar examples of invertebrates include insects, worms,clams, crabs, octopuses, snails, and starfish.

Vertebrates are animalsthat are members of the subphyla.Vertebrates include the overwhelming majority of the phylumChordata, with currently about 64,000species described.Vertebrates include the jawless fish and the jawed vertebrates, which includes thecartilaginous fish (sharks and rays) and the bony fish.

The time

If I have the power to stop the clock I would go back to the first day in the school because I want to be more time with Gaby. 

August 

All of my friends present to the new students. In the first days we played games to know about new students and we borght the new books.

September 

We did our first exam, I learnt new things, and we celebrated Independence day we dance and sing 

October 

We did our second exam,all the new students were my best friends,and the students of 7th grade did the scare house. The scare house was very nice.

Bloque III Ciencias naturales

Conoce sobre: el estado de la materia.

1. ¿ En qué estado físico está el agua?

Líquido💧.

2. ¿ Qué es el estado físico?

Es el estado de la materia.😧

Lo que me faltó:

 Un estado físico es cada una de las situaciones o formas físicamente distinguibles mediante la medición de alguna propiedad que puede adoptar un sistema físico en su evolución temporal.

3. ¿ En  qué estado físico esta la piedra?

Sólido.🌑

4. ¿ En qué estado físico esta el aire?

Gaseoso.💨

5. ¿Qué es un liquído?

 Es un estado físico.😧

Lo que me faltó:

Sustancia cuyas partículas presentan mayor movilidad que los sólidos y menor que los gases, y no presentan una forma propia determinada, pero sí un volumen fijo que se distribuye en el recipiente que lo contiene adaptándose a su forma.

6. ¿ Cómo el liquido se puede convertir en sólido?

Enfriando el liquido.❄️

7. ¿ Cómo el liquido1. ¿ En qué estado físico está el agua?

Líquido💧.

8. ¿ El líquido tiene forma definida?

No, se adapta a una forma indefinida. se puede convertir en gaseoso?
