Module 53

Die gebruik van materie in ons huise

Aktiwiteit:

Om saam te kan gesels oor die gebruik van materie in ons huise, veral plastiek

[lu 1.1.1]

Plastiek

Dink gou aan enige gebruik vir ‘n plastieksak. Moenie net aan gewone alledaagse dinge dink nie, wees kreatief en dink oulike idees uit. Hoeveel gebruike kon julle groep in 2 minute uitdink? Gee terugvoering aan die klas.

Probeer die volgende (1):

Neem ‘n joghurtbakkie, ‘n rekkie en sommige van die volgende materiale: kombuispapier, karton, wol, katoen, tinfoelie, plastiek, ‘n servet. Neem elkeen van die materiale, plaas dit op die joghurtbakkie en bind die rekkie om. Drup ‘n teelepel water op elke stuk materiaal en kyk wat gebeur. Syfer die water deur?

Wat was die beste materiaal om die water uit te hou?

Probeer die volgende (2):

Kom ons maak ‘n valskermpie. Gebruik die volgende materiale om ‘n valskerm te maak en gooi dit elke keer van dieselfde hoogte af: koerantpapier, plastiek, katoensakdoek, karton, sneesdoekie, skryfpapier. Kyk watter materiale werk die beste.

Skryf die lede van julle gesin se name onder mekaar neer. Skryf die plastiekitems wat hulle daagliks gebruik, langs elkeen se naam neer. Wie gebruik die meeste plastiekitems in julle huis?

Ongelukkig neem dit baie lank vir plastiek om te ontbind. Die regering het vanaf 2003 standpunt hieroor ingeneem en alle gratis plastieksakke by winkels verbied. Kliënte moet nou hulle eie inkopiesakke saamneem wanneer hulle inkopies doen, of moet nuwes koop.

Hou ‘n redenaarskompetisie om hierdie aspek te bespreek.

Ontwerp ‘n nuwe soort winkeldrasak om die probleme wat bespreek is, op te los.

Plak alle soorte plastiek wat jy in jou huis kan kry op 'n vel papier

Tot onlangs was die plastieksakke ‘n groot probleem in ons pragtige land, want dit het ons land ontsier deurdat dit oral rondgelê het. Dink net waar hierdie sakke oral beland het en waarvoor dit alles gebruik en misbruik is.

Jy tel ‘n plastieksak in die straat op. Dit is vuil, geskeur en vol gemors. Die plastieksak se naam is Plassie. Teken nou ‘n strokiesprent oor die lewe wat Plassie tot nou toe gelei het: ‘n lewe vol gevaar, met baie wedervaringe, maar tog het hy oral ‘n goeie doel gedien.

Assessering

LEERUITKOMS 1: WETENSKAPLIKE ONDERSOEK

Die l eerder is in staat om met selfvertroue op weetgierigheid oor natuurlike verskynsels te reageer, en om binne die konteks van wetenskap, tegnologie en die omgewing verbande te ondersoek en probleme op te los.

explain how nature and nurture affect the development and later the productivity of an individual.
Amesalu Reply
nature is an hereditary factor while nurture is an environmental factor which constitute an individual personality. so if an individual's parent has a deviant behavior and was also brought up in an deviant environment, observation of the behavior and the inborn trait we make the individual deviant.

I am taking this course because I am hoping that I could somehow learn more about my chosen field of interest and due to the fact that being a PsyD really ignites my passion as an individual the more I hope to learn about developing and literally explore the complexity of my critical thinking skills
