The body as a machine

Standard

The human body is a machine consisting of many different, interconnected machines. Each machine (heart, lungs, intestines, etc.) runs at its own individual speed, but all function in a specific, predetermined relationship to each other. In this sense, the body is analogous to the most complicated man-made machines, such as automobiles, tape recorders, or space capsules, which consist of many separately functioning components that are mechanically linked together, each of which, in itself, is a complete machine. In fact, the body is the most complex of all such compound machines. But unlike man-made machines, the various machines that make up the body are not in a rigid, inflexible, unchanging interrelation to each other.

Autumn leaves

Standard

2013-11-13 10.35.291

Autumn is here and our playground is full of leaves.

This beautiful scenery (our playground) and some activities I’ve seen in pinterest gave me the idea to do this craft.

It’s an easy one and children loved it.

First it all we used white cardboard paper and we placed some pieces of crepe paper (in different colors) in the pattern we wished. We let our imagination run wild with this technique.We made random patterns and  it was lots of fun.

Then we sprayed liberally with water. The more water we sprayed on the crepe paper the more intense the color transferred.

We pressed down to make sure the water penetrates and we left them for 10 minutes. After that we removed the layers and we let them dry and We waited until the next day to paint the trees.

Using the black/brown watercolor and a paint brush, we painted a tree trunk on our horizon line. Then we dipped our paintbrushes into the black/brown watercolor and we made some little puddles at the top of our tree trunk.  With our straws we blew the watercolor up and across our paper to make branches.  We continued making puddles on our trunks or on branches and blew the watercolor in various directions.

When it was completely dried  (it didn’t  take long) we collected  some dry autumn leaves from our playground. The leaves were very dry so they crunched up nicely. We crunched our leaves and we glued them where we wanted the leaves to be. And… it was done! Aren’t they pretty?

A happy farewell!!!

Standard

I don’t really know how to begin.

Three days left and our fun and exciting school year will come to an end and summer officially will begin. As a teacher, I’ll certainly miss all of my students. You have grown so much and developed so many wonderful friendships along the way. Hope you remember these two great years we spent together.

It was a pleasure to be your teacher during these two years. I’m really proud of you all. I’ll miss you next year, even my little chatterbox 🙂

You can download these photo and print it if you like. Two options: with and without frame you chose.

We have been busy learning about the moon. Here are the things we have been busy doing. We read nonfiction books about the moon and learned about its phases. We  made the phases of the moon and labeled them.

We used a class take home journal to record the phases of the moon.

We made several fun moon crafts and activities with the moon and the sweet phases of the moon.

Learning from history

Standard

We’ve just started one of my favourite units in Science:

“Learning from history”

This unit is divided in two periods: Prehistory and History:

preTitle Prehistory is the period that began when humans appeared on Earth and ended with the invention of writing.
The prehistoric people were nomads because they lived in small groups and moved constantly in search for food. They ate wild fruits and animals they hunted and fished.
They lived in caves and built tools, weapons and ornaments with bones and stones. His greatest discovery was fire.

History is divided in four stages:
Antiquity (Ancient History). Earliest civilizations with writing.
The Middle Ages. Began about 1500 years ago.
The Modern Age. It started about five hundred years ago.
The Contemporary Age. It started about two hundred years ago and extends to the present.

The next one is in Spanish but is an amazing time machine that will help you to travel back to the different periods

Roman civilization belongs to the Old Age and emerged in present Italy.
The Roman population consisted of free men and slaves. Slaves were owned by other people that made them work very hard.
The capital of the Roman Empire was Rome and it was ruled by an emperor. The language of the Romans was Latin.

HOW DID ROMANS LIVE?
Many Romans lived in cities surrounded with a wall. To carry water from one city to another they built aqueducts, (in Segovia is one of the best preserved).
In the Roman cities were different types of building such as circuses, theaters, amphitheatres, temples, markets, public baths,  justice buildings, etc..http://
The cities of the empire were connected to each other by causeways.

The Contemporary Age

This age is the one in which we live. In the early nineteenth century, the invention of the steam engine. This invention was applied to the industry and it was able to make many products in a short time. We also used in transportation the steam engine to make  trains, cars and planes.

Great advances have been achieved  since then like:
Medical advances such as radiography, antibiotics, anesthesia or vaccines.
Technological advances such as the automobile, the airplane, the rocket, computer, television and appliances.
Advances in lifestyle with schools that serve all children, homes for the elderly people , hospitals …
