KEY CONCEPTS, KEY FOCUS and IMPLICATIONS for TEACHING & LEARNING of Technology through the RNCS
Grade 7
Investigates: background context Existing products - examine- (relevant to problem and based on key design aspects) Practical tests / testing Data handling (plan, collect, extract, copyright laws, summarise & present)	Systems & Control: Changing direction of movement and/or the value of force (using the components of mechanical systems, hydraulic and pneumatic included) Input - Process - Output Drawing system diagrams. Series and parallel electrical circuits ( with more than one output device) Input - Process - Output Drawing system diagrams	Impacts: technological products (Express reasons for positive and/or negative effects on quality of life)
Designs : Design brief Lists specifications and constraints based on specified design aspects. possible solutions- alternative- (linked to design brief & specifications and/or constraints.) choice of solution with reasons chosen solution developed further -(graphics or modeling)	Processing: Conditioning a material to change or improve specific properties (strength, fire resistance, waterproofing, taste, volume, texture, etc.)	Biases : technological products (Express opinion on advantage or disadvantage on certain sectors of society)
Makes : Planning Materials list Tools list Construction techniques Safety, material and tool use	Structures: Use of materials in structures based on their properties. Stability in terms of size, shape & form Strengthening parts of and/or complete structures	Indigenous Technology: indigenous cultures in South Africa (Explain the use of specific materials with reasons for the differences)
Evaluates: identifying Strengths and weaknesses of: Product , System and of plan of action Use criteria for evaluation suggestions for improvement / modification
Communicates: 2D (1st / 3rd angle) or 3D (isometric, perspective, oblique) enhanced sketches / drawings (colour/ shading/ rendering) circuit diagrams (circuit symbols) systems diagrams (input, process, output) notes, labels, dimensions, list of quantities. SA drawing conventions (for above) Appropriate use of Technology to present information.
