Rules regarding hygiene

ACTIVITY 1:

To be able to name and apply the rules regarding hygiene.

  • Bacteria cause food decay, which can result in food infection or food poisoning. It is essential for food to be protected against harmful bacteria. In order to do so, a few basic rules must be applied in the kitchen and also with regard to personal hygiene.
  • The drawings that follow illustrate aspects of hygiene in the kitchen, as well as personal hygiene.
  • Write down a rule of hygiene deduced from each picture.

Assessment

Learning Outcomes(LOs)
LO 1
TECHNOLOGICAL PROCESSES AND SKILLS The learner will be able to apply technological processes and skills ethically and responsibly using appropriate information and communication technology.
This is demonstrated when the learner:
investigates:1.1 investigates the background context, the nature of the need, the environmental situation, and the people concerned when given a problem, need or opportunity set in a nationally relevant context;
1.3 develops and performs practical tests in the technological areas (Structures, Processing, and Systems and Control);
1.4 uses appropriate technologies and methods to:
  • collect relevant data from different sources and resources;
  • extract relevant data;
  • make meaningful summaries;use information to justify and support decisions and ideas;
designs:1.5 writes or communicates a short and clear statement or a design brief in response to a given identified situation for the development of a product or system;
1.6 lists product and design specifications and constraints for a solution to an identified or given problem, need or opportunity based on most of the design key words listed below:
    • people: age target market;
  • purpose: function;
  • appearance: colour, shape;
  • environment: where will product be used;
  • safety: for users;
  • cost: cost of materials;
1.7 generates several alternative solutions and writes notes, ideas that show some links to the design brief and specifications;
makes:1.9 develops a plan for making that outlines all of the following:
  • resources needed;
  • sketches showing the necessary dimensions or quantities;
  • all steps necessary to making the product (makes);
1.10 chooses and uses appropriate tools and materials to make products by measuring, marking, cutting or separating, shaping or forming, joining or combining, and finishing different materials accurately using appropriate techniques;
1.12 uses safe working practices and shows awareness of efficient ways of using materials and tools;
evaluates:1.13 tests and evaluates the products or systems with objectivity, based on objective criteria linked to the design brief, specifications and constraints, and suggests sensible improvements or modifications;
communicates:1.15 presents ideas using two-dimensional or three dimensional sketches, circuit diagrams or systems diagrams that include all of the following features:
  • use of SA drawing conventions (e.g. dimension lines, labelling, line types, symbols);
  • notes to clarify and communicate design features and reasoning; enhancement of significant sketches like final solution drawings.

Memorandum

ACTIVITY 1

  • Allow learners to write down their own rules, present them to the class and then respond to the reactions from the class.
