MAGNETISM



WHO DISCOVERED THE MAGNET?
>>>>>>>>>>>>>>>>SHEPHERD MAGNES STORY


magnetism for kids

magnetic field

>>>how the magnets work

MAGNETIC FIELD EARTH


What is a magnetic field?

How compass works?


ELECTROMAGNETISMO


how liquids impact a magnet.EXPERIMENT
Materials: 3 glasses, a magnet, 12 paper metal clips, some water, some olive oil and some syrup
How does the experiment work?
when using water and olive oil, the paper clips moved through the liquid to the magnet very quickly. This is because the liquids provided very little resistance. 
However, the paper metal clip in the syrup moved very slowly toward the magnet.This is because the syrup has a very think consistency.

IT CAN ATTRACT OBJECTS MADE OF IRON OR MIXTURES OF IRON.

IT IS THE ATTRACTION CREATED BY A MAGNET.

REVIEW. ELECTRICITY

CIRCUIT SYMBOLS

SYMBOL
PURPOSE
EXAMPLE

It provides electrical energy



LAMP/ BULB
It transforms electrical energy into light



WIRE
It allows current to travel / flow





SWITCH(OPEN)
It allows the circuit to be turned off so that the electricity cannot pass


SWITCH(CLOSED)
                                                                                  
It allows circuit to be closed so that the electricity can pass

MOTOR
It transforms electrical energy into movement energy (mechanical energy)

series or parallel circuits




SERIES CIRCUIT: there is only one pathway for electricity.If it is open, the flow of the current stops.
PARALLEL CIRCUIT: there are two or more pathways for electricity current to flow. If one pathway is open, the other one still works.

10.                     WHAT ARE MACHINES: CLASSIFICATION
11.                     TYPES OF SIMPLE MACHINES. EXAMPLES. EXPLAIN ONE SIMPLE MACHINE
12.                     COMPONENTS  OF COMPOUND MACHINES
13.                     PARTS OF A BICYCLE

14.                     CLASSIFICATION OF MACHINES BY THE ENERGY SOURCE AND THEIR FUNCTION

























ELECTRIC CIRCUIT. MATERIALS

We start the unit: Electricity.

You are going to experiment with the electricity in class.

Finally, you have to make an electrical circuit.

You need to buy:

2 electrical wires--- 2 cables eléctricos(1.5 o menos), de distinto color y de un metro cada uno 

 a battery 4,5V (una pila de petaca: 4,5voltios)
a light bulb 5V (una bombilla 5voltios)

an adhesive tape (cinta aislante)

a switch (un interruptor)

a lamp socket (portalámparas)


Este portalámparas es más práctico y fácil de manejar




Para realizar el proyecto final, vas a  necesitar apoyarte en 
 madera de contrachapado o tablero DM 
o
También algo firme como un cartón.

LEARNING ABOUT INVENTORS. The theory of electricity




This week we are going to start a new project. All about inventors. We are going to investigate about inventors, their inventions and how different inventions help us.
