What is a lens?

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.

BIODIVERSITEIT: AANPASSINGS EN OORLEWING

Module 24

FOSSIELE

Fossiele is die oorblyfsels van dooie plante, diere, bakterieë en ander lewensvorme wat miljoene jare gelede geleef en toe versteen het.

Fossiele is dus versteende oorblyfsels van organismes, bv. tande, bene, bas of skulpe. Dit kan ook spore of afval van organismes wees.

1. Wanneer ’n dier/organismes doodgaan vergaan die sagte dele eerste. Die res word in die sand of modder bedek.

2. Oor miljoene jare vind chemiese veranderinge sowel as drukking plaas wat dit laat versteen.

3. Water wat deursyfer kan ook veranderinge teweeg bring. Die vorms word goed behou.

4. Beweging van die aardplate bring die fossiele na die oppervlak.

Aktiwiteit: OM NAVORSING OOR FOSSIELE TE DOEN

  • Wat is ’n paleontoloog?

OPDRAG: Teken ’n vloeidiagram om die fossielvormingsproses eenvoudig voor te stel.

Assessering van vloeidiagram:

Kon jy ’n sinvolle vloeidiagram van die fossielvormingsproses teken?

[LU 2.2]

Aanpassings – Fossiele

AKTIWITEIT:

  • Bestudeer die volgende prente van fossiele en probeer afleidings maak t.o.v. hul voeding en bewegings:

Figure 1
Figure 1 (graphics1.jpg)

Skedel van ’n Suid-Afrikaanse dinosourus (Mossospondvlus)

Figure 2
Figure 2 (graphics2.jpg)

Brachiopoda skulpe in ’n 500 – 300 miljoen jaar oue strandneersaksel

Figure 3
Figure 3 (graphics3.jpg)

Skedel van ’n Suid-Afrikaanse dinosourus (Mossospondvlus)

Figure 4
Figure 4 (graphics4.jpg)

’n Vlieg wat in die 90 miljoen jaar oue neerslae van die Orapa diamantkrater gevind is (Botswana)

Assessering van afleiding:

Kon jy die korrekte afleidings t.o.v. die fossielsketse maak?
