Natural Sciences and Technology Grade 6 Term 3: Energy and Change Systems to Solve Problems
Topic 3 Systems to solve problems Natural Sciences and Technology - Grade 6
Vocabulary Design Design is the creation of a plan to construct [buildings, clothes, cupboards, electrical circuits, toys, etc.] It includes a sketch or plans to show the look and function or workings of the objects that will be designed before it is made. Natural Sciences and Technology - Grade 6
Design: An example of a toy [rough sketch] Natural Sciences and Technology - Grade 6
Vocabulary Specifications Information about the project and it is specially made to meet a unique need. Information about the requirements for a product and how the product is to be put together. For example: - made from recycled material - light weight - include mechanisms that allow movement - safe to use - no sharp edges - not expensive Natural Sciences and Technology - Grade 6
Vocabulary Evaluate Look at the advantages and disadvantages of the design. Determine whether all the criteria were met [weight, edges, user friendly, recycled material, etc.] How the parts were joined. Can the toy move? Natural Sciences and Technology - Grade 6
Vocabulary Constraints Something that limits or restricts a product: Not enough money for the design. Material is too heavy. Cannot find the proper recycling material. Edges are not smooth. Toy does not move properly. Natural Sciences and Technology - Grade 6
Vocabulary Draw To produce a picture or a diagram by making marks and lines on paper with a pencil or pen. Natural Sciences and Technology - Grade 6
