Grade 4
Investigates: background context to situation Existing products – identify main design aspects science process skills (if appropriate)	Systems & Control: Produce motion using simple mechanisms Input - Output	Impacts: technological products (express opinions on how these products makes lives easier)
Designs: Design brief possible solutions (linked to design brief & specifications and/or constraints.) choice of solution with reasons	Processing: Properties of materials (Physical & Chemical) and the influence these properties have on the effectiveness of products.	Biases : technological products (Express opinions on how certain groups are disadvantaged by these products)
Makes : Planning Materials list Tools list Neatness and safety	Structures: Strengthening parts of and/or complete structures.	Indigenous Technology: Local Indigenous cultures (Describe use of scientific principles & technological products for specific purposes)
Evaluates : - with assistance Product according to brief Suggests improvements/modifications to product if necessary
Communicates: 2D (1st ) *enhanced sketches / drawings (colour/ shading/ rendering) systems diagrams (input, process, output) notes, labels, dimensions SA drawing conventions (for above)
