Magnets - Caoimhe 6th class


Today we measured the distance a paepr clip needed to be from a magnet before it is attracted to the magnet. We used varying magnets and numbers of paper clips to test this. Below is a grpah of my results also.
1 paper clip is approxemitaly 3cm south
2 paper clips is approximately 4cm south
3 paper clips is approximately 3cm south
4cm paper clip is approximately 3.5cm south

1paper clips is approximately 3cm north
2paper clips is approximately 5cm north
3paper clips is approximately 6cm morth
4paper clips is approximately 6.5cm north





4 th, 5 th and 6 th class are doing an experiment at the moment on how magnets work.
In the survey above, I am showing the measurement of the magnet and how many centimetres away would attract a paper clip

The generator - Caoimhe
When you use water to turn a wheel it can generate electricity.
The faster the water the quicker the genorator will turn amd the more electricity will be created. When this is attached to a
light the bulb will illuminate once electricity flows. The quicker the generator turns the brighter the bulb will light. Generators
can be powered by renewable resources such as water which is used in Ardnacrusha; wind in Lisheen, waves on the western coast of
Ireland is also being looked at. Fossil feuls are also used in bord na mona power stations in Edenderry to generate elecricity.
