A primary aim of this site is to provide a resource for use in the IT-equiped classroom.

The site covers all relevant Leaving Cert. Physics material as well as extra background information.

Ideal for introducing or revising the topic.

Suggestion:
Check the Syllabus and view the Contents Grid to select areas you wish to use this site for.

 

This website was designed as a resource for those who wish to learn about the electron.

A primary concern in the way the site has been structured is to meet the needs of teachers who wish to use it in the classroom.

Teachers might first review the site, select what areas will meet their students needs and devise a scheme of work and an appropriate time scale. (e.g. Use three 40 minutes sessions for the topic).

Naturally students may wish to use this website on their own, and pursue the subject of the electron in their own way at a pace that suits them.

Some students may find it serves their needs best as a revision aid.

Hopefully the general reader will find it accessible and informative.

The Leaving Certificate Syllabus for Physics, has the same entry for Higher Level as for Lower Level. Therefore the same material may be covered for both.
To check the Syllabus click here or read the excerpt below.

The sitemap and the Contents Grid are both worth checking to guide students to use this website in the way you wish them to.Find what you are looking for in the grid and then link directly to the page it is on.

The Electron

1. The Electron as the indivisible quantity of charge.

Reference to mass and location atom.

Units of energy: eV, keV, MeV,

STS:-      Electron named by Stoney;
             Quantity of charge measured by Millikan

2. Thermionic emission

Principle of thermionic emission and its application to the production of a beam of electrons.

Cathode ray tube consisting of heated filament, cathode, anode, screen. Deflection of cathode rays in electric and magnetic fields.

Activities Use of Cathode Ray tube to demonstrate the production of a beam of electrons---deflection in electric and magnetic fields.

STS:-      Applications: CRO; Television: Use of CRO to display signals:              ECG and EEG
