Pulleys are other simple maachines form by a wheel and rope,you see a lot of things about pulleys

UNIT 5 - TOGETHER.

An interesting video about pulleys,you can see that works and uses.Pulleys

UNIT 5 - INCLINATED PLANE

I see these videos and i like a lot and i would like that you see.This is about planes inclinated.You hope it

UNIT 5 - WHEELS

Can you see more videos about simple machines.They are funny videos that you can spend a good time while you are learning.

UNIT 5 - LEVERS

The simple machines are present in our lifes.They are very important por us that you know how they work.Can you see a video about levers.

UNIT 5 - Can you identify these mechanisms?

In this video, you can see some mechanisms constructed with Lego that we have studied in class. Can you identify them?

UNIT 5 - PULLEY (EXERCISES)

It is form with a wheel that it has a central orifice that permit rotate fixed or freely on its axis,has got a channel in its periphery for can drag or be drag for one rope,chain,belt... There are different types of pulleys FIXED PULLEY:formula(F=R) MOVABLE PULLEY:formula(F=R/2) HERE WE HAVE SOME EXERCISE FOR PRACTISE THE PULLEYS.(interesting,and good for revise) http://www.educa2.madrid.org/web/educamadrid/principal/files/a1c18b06-dde8-4e44-98a0-49f0e0f2c425/M%c3%81QUINAS%20Y%20MECANISMOS/M%c3%a1quinas%20y%20mecanismos.pdf

UNIT 5 - RESOURCES

Some resources for review this unit:

- Here you have an interesing game to know the use of the simple machines (inclined plane, level, wheels, pulley) This is a game of the museum of the Science of Chicago. Try to obtend the objects with simple machines!

- In this web, you can see a section of mechanisms and you can find a lot of webs, presentations, notes and animations for review this unit.

UNIT 5 - HOUSE OF MACHINES

This is a good example of connected mechanisms in which you can see a house of machines in which there are mechanims made with wood. 

UNIT 5 - MACHINES

Machines are something that helps you use energy and more effectively.One of the simple machine is the inclined plane which allows you to trade increased distance for decreased effort or force:by doubling the distance you move a thing,you can half the force you need to exert.

UNIT 5 - "THE GREAT SEARCH"

Here we have a short video in which you can see the evolution of the technology with the use of the energy souces and simple machines. Hope you like it:)

UNIT 5 - Mechanisms

Man builds objects for meet his needs and improve his quality of life. If you look around you, you can see that the majority of this objects have or produce some kind of movement with a purpose, like: clear the clothes, indicate the time, move people...

Here we have the example of a coffee grinder. It has a  simple operation and it´s based on a lever on the top that turns gears of the machine and the grains of coffe become pulverized. The result is collected in a drawer and it´s ready for be taken in a cup of coffee.
