Definition of a lens

Lenses

A lens is a custom view of the content in the repository. You can think of it as a fancy kind of list that will let you see content through the eyes of organizations and people you trust.

What is in a lens?

Lens makers point to materials (modules and collections), creating a guide that includes their own comments and descriptive tags about the content.

Who can create a lens?

Any individual member, a community, or a respected organization.

What are tags? tag icon

Tags are descriptors added by lens makers to help label content, attaching a vocabulary that is meaningful in the context of the lens.

MOLEKULES

Klasaktiwiteit

Bou Molekule

  • Verdeel die balletjies in drie groepe volgens kleure.
  • Elke kleur (patroon) stel ‘n groep atome voor.

Beantwoord die volgende vrae deur na bostaande te verwys:

1. Hier (A) het jy ‘n molekuul gebou wat beter bekend is as

Hier (B) het jy ‘n molekuul gebou wat beter bekend is as

2. Wat dink jy word deur die stokkies voorgestel?

3. Molekule is dus samestellings van

4. Hoe lyk suurstofgas?

5. En osoon?

Assessering van modelbou-aktiwiteit

Kon jy die modelletjies bou?

[LU 2.2; 2.3]

Opdrag

Volhoubare Bronne

  • Vind uit wat osoon is en waarom dit so belangrik is vir lewe op aarde.
  • Doen verslag hieroor aan die klas as deel van 'n bewusmakingsveldtog oor hulpbronne in gevaar.
  • Hou 'n uitstalling in die klas of skool.

Assessering van bewusmakingsveldtog

Het jy deelgeneem aan die veldtog om ander bewus te maak van die osoonlaag en al die kwessies wat daarmee verband hou?

[LU 3.2]

Assessering

LU 2

Wetenskaplike Kennis

Die leerder ken, interpreteer en pas wetenskaplike, tegnologiese en omgewingskennis toe.

Dit is bewys as die leerder:

2.1 sinvolle inligting kan onthou;

2.2 inligting in kategorieë kan plaas;

2.3 inligting kan interpreteer;

2.4 kennis kan toepas.

LU 3

Wetenskap, die Gemeenskap en die Omgewing

Die leerder is in staat om begrip van die onderlinge verband tussen wetenskap en tegnologie, die samelewing en die omgewing te toon.

Dit is bewys as die leerder:

3.1 wetenskap as ‘n menslike aktiwiteit kan verstaan;

3.2 volhoubare gebruik van die aarde se hulpbronne verstaan.
