What the work shows

Sarah has an elementary understanding of abstract scientific principles related to the field of electricity and uses meaningful scientific terms appropriate to a context. She is able to use her understanding of electricity to explain how everyday objects use it. However, her ability to "think in scientific ways" is less advanced.

Progress Indicators

Thinking in Scientific Ways

Suggesting explanations
Sarah can suggest cause-effect links for observations or events but has difficulty explaining them. She uses simple diagrams to explain her ideas (L2).

Developing and Communicating Scientific Understanding

Using scientific ideas in constructing explanations
Sarah constructs a plausible explanation of how electricity moves through a wire using some scientific ideas. She uses her knowledge that atoms have electrons but becomes a bit confused when attempting to link the abstract notion of electrons to the flow of electricity.

In her explanation of how a toaster uses electricity to toast bread, Sarah constructs a plausible explanation of the concept of resistance in electricity, using some scientific ideas. She is beginning to link her ideas to provide a better explanation.

Using scientific vocabulary
Sarah is beginning to use a range of scientific terms appropriately, with increasing reference to abstract ideas. For example, in answer to the question "What is electricity?" she used the terms "atoms", "electrons", and "electrons flow" (L5).
