What Makes a Magnet

Magnets come in two types. Electromagnets are created by applying electricity to a conductive material like iron. Natural magnets can be anything from the Earth itself, including individually magnetized rocks like lodestone. Scientists don't understand how the electrical current that magnetizes the Earth and some of its rocks is produced.

Magnetic Fields

If you hold a magnet under a piece of paper and sprinkle iron filings on the paper, the filings seem to dance around and eventually settle in a rough oval around the magnet. They are aligning themselves with the magnetic field, or the path the magnet's electricity takes to get from one end of the magnet to the other. These fields of electricity are like closed circles rotating through the magnet. Magnetic fields are the reason magnets are either repelled from or attracted to each other.

Magnetic Poles

All magnets have a north and south pole. These poles are created by the fields of electricity moving through the magnets. Electricity enters the magnet at the south pole and exits it at the north pole. This is why like poles repel each other. Electricity exiting one north pole can only bump up against another north pole; it can't enter it. And it's the same story at the south pole: Electricity can only enter at the south poles, so two south poles are forced apart. However, if you line the south pole of a magnet up to the north pole of another magnet, the energy exiting the north pole of the first magnet can travel into the south pole of the second magnet, in effect creating a new magnet.

PARTES DE LA PLANTA DE UNA LENTEJA. LENTIL PLANT PARTS

LENTEJAS (lentils)

¿CÓMO CRECEN NUESTRAS LENTEJAS?
How do our lentils grow?

   

Plantamos semillas de lenteja y les pusimos agua, durante una semana han quedado así, han brotado unas raíces con unos tallos verdes
We plant lentil seeds and we add water. Seven days later, our lentils are like this. They have roots and long stems. 

We can see their parts in this last picture.

Pasadas dos semanas nuestras lentejas están suuuuuper altas. TOO WEEKS AGO...

The best work
