Other Work Samples for:

Riley has demonstrated a sound knowledge and understanding of buoyancy. Riley has made predictions about which materials would float and then selected and used appropriate materials to construct a structure for testing. The results were adequately recorded but inconsistent with the prediction of items that were buoyant. Riley provided an adequate explanation as to why the object did not float. A drawing rather than a labelled diagram was provided. This work sample demonstrates characteristics of work typically produced by a student performing at grade C standard.

Grade C

The student has a sound knowledge and understanding of the main areas of content and has achieved an adequate level of competence in the processes and skills.

Foundation Statement strands

The following strands are covered in this activity:

  • Investigating Scientifically
    Students conduct guided investigations by following a series of steps that include questioning, making and testing predictions, collecting and recording data, observing patterns and suggesting possible explanations. They select and safely use a range of equipment, computer-based technology and other resources to investigate and explore.
  • Designing and Making
    Students follow a guided design process to create products, including information products, services and built environments. They draw and model design ideas using accepted methods and practices. They select and safely use a range of equipment, computer-based technology and other resources when designing and making.
  • The Made Environment
    Students identify the difference between natural and built environments and model built environments designed to suit the needs of users. They communicate messages using a variety of media and technologies. Students describe and apply production processes using a range of materials and techniques to grow, make or process products.
