Web search on how a touch screen works.
Select reliable, authoritative sources. Need whole class discussion on what makes a source authoritative.
Plagiarism - referencing of sources, must include sources of diagrams in thia (see mycricket link above)

What makes a site appropriate? Discuss what to look for in a site, deciding whether the site is pitching inforamtion at the correct level.
e.g. Not suitable if there are 5 words on page that you don't understand.

Should there be a specific type of screen or allow any screen to be reserached? Technology is more relevant if the resistive screen is used - easier to understand? Capacitor too advanced for this level? Yes for Nat4, maybe not for Nat5.
