What the work shows

Elliot's two pieces of work are part of an extensive unit exploring circuits and how they work. The supported investigation followed the same pattern throughout: predict what you think will happen, try out your ideas, describe what you think is happening, and explain what you think is happening and the reasons why it is happening. Elliot's work shows a shift in understanding from his initial clear but invented view to a more accurate explanation of how a torch works.

Investigating in Science

Exploring a situation
Initially, Elliot mistakenly thought that a motor inside the torch made it work. His "before" view shows that he makes observations and looks for patterns or relationships between a switch and the glowing bulb.

Using systematic approaches and scientific conventions
Elliot's "before" view also shows that he had carried out simple trials based on his own ideas.

Processing and interpreting
Elliot is moving towards level 2 in this aspect. With prompting, he reaches a conclusion in a simple investigation into how a torch works (L1).

Reporting
Elliott uses a diagram to report on his investigation in an organised way, referring to his observation that a bulb needs a circuit in order to give light.

Developing and Communicating Scientific Understanding

Using scientific ideas in constructing explanations
Elliot is able to offer explanations for his experiences using some scientific explanations. He's beginning to use drawings as simple aids in his explanations. In his "after" view diagram, he explains his observations of how a torch works and shows some understanding of the scientific ideas related to his experiences. He links the ideas to an event but does not explain the link.

Elliot uses the evidence gained through his investigation to change his views. His "after" view does not now refer to a motor being necessary to make the batteries and bulb start.

He demonstrates increasing precision in his drawing of the light beam.
