Module 18

Water

Aktiwiteit:

Om die belangrikheid van water te bespreek

[lu 1.3]

Luister mooi na die storie oor water wat jou onderwyser vir jou gaan lees, en bespreek dan die inligting in die waterdruppel hier onder.

Water is lewe

Water speel ‘n baie belangrike rol in die ekosisteem, want dit hou diere en plante aan die lewe. Geen lewende wese kan sonder water oorleef nie.

Plante: Ons weet dat sekere soort plante slegs in water groei. Dink maar net aan die pragtige waterlelies met hul groot, plat blare wat op die water dryf.

Diere: Diere drink ook water om te lewe. Dit is noodsaaklik vir diere wat in, op en naby water lewe.

Bespreek die volgende in jou groep:

Wat sal gebeur as ons skool vir ‘n uur lank sonder water is?

Wat sal gebeur as ons dorp/stad vir ‘n uur lank sonder water is?

Wat sal gebeur as ons land vir ‘n uur lank sonder water is?

Hoekom is water so belangrik?

Opdrag:

Voltooi die blokkies met die beste antwoorde wat jou groep gegee het.

Assessering

LU 1

Dit is duidelik wanneer die leerder:

1.1   ondersoek beplan;

1.2   ondersoek uitvoer en data versamel;

1.3       data evalueer en bevindings kommunikeer.
