Latest Magnetic Celestia

Press enter and type "Magnetic Earth" enter and then 'g' to go.
This will take you to a magnetic field earth. The field lines go through space. There are various types of trapped particles that spiral in the field lines forming the radiation belts of the earth.

Also check out "Magnetic Dwarf" for giant space magnets.

Press enter and type " Earth's Interior" then enter, then 'g' . this will take you to an earth where the interior is shown. Scientist are still struggling to explain the earth's magnetic field and how it could be generated from this structure.

Also "ISS" will take you to the international space station. It is still in the Earth's gravity, but as as everything is falling, there is no gravitational force between things that are falling.

Advanced Electrostatics.

This simulation show that only electrons move to and from objects and that charges induce or "polarize" objects. Make notes of this in your work book. Note charges are not coloured. Electrons are only "visible" as the silver in metals. The positively charge nucleus are a fixed latice.

This simulation shows the two types of charge, Note in your book how these charges behave.

Communication and Forces

'In World War II in Great Britain, all church bells were silenced, to ring only to inform of an invasion by enemy troops. The episode "The Battle of Godfrey's Cottage" of the BBC sitcom "Dad's Army" included a scene where the church bells rang by mistake, leading the Home Guard to believe that an invasion was taking place.

From student LF.

Bells was Europe's communication and control mechanism. Around the middle ages every village had a church with bell tower. Bells rang to communicate time and when it was time for prayer. We use bells in this school. There were also bell tunes for specific events.

The North American Indian are famous for using smoke signals.

This lesson we saw the fascinating interaction of electric charge and the bodies own internal communication system of nerves as the hand jumps.
