Content

Activity: to indicate the routes taken by early discoverers who navigated by the stars [lo 2.3]

Early discoverers steered their boats using the sun by day and the stars by night and used very simple instruments to determine their direction.

Do research on the early voyages of discovery and draw a map of the world. Add captions to identify the continents and the main oceans. Give the map with a heading and indicate north. (Decide on a suitable size yourself.)

Choose two of the following voyagers and show the routes that they had taken on their voyages of discovery. If the discoverer undertook more than one voyage, this should be shown clearly.

  • Bartholomew Diaz
  • Vasco da Gama
  • Christopher Columbus
  • Ferdinand Magellan
  • David Livingstone
  • Marco Polo
  • Robert Scott
  • Francis Drake

Try to create the impression that your map is an ancient map, one that might have been used by the particular discoverer.

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
s.
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
Tarell
what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
