Physics - Scientif ic Explanations
I can collect, organise and present information I can make appropriate improvements to work based on feedback 1

I can describe familiar events. What ? How ?
I can make a simple scientif ic observation.
I can make a correct scientif ic statement but I do not explain it of give a reason to support it.

I can explain familiar events
Why ? . Because ? .
I can make simple connections between ideas e.g. this is happening because of that
I can give a sensible reason for my answer but do not always fully explain or sometimes make mistakes.
I use a scientif ic model to help me explain
I can explain things that we cannot normally see e.g. how particles cause things to happen
I can make multiple connections between ideas e.g. this is causing that to happen because of . . .
I can use more than one piece of evidence to support my answer including data, graphs and charts.
I can apply abstract scientif ic models in new situations
I can explain complex ideas that require a high level of scientif ic understanding and make accurate generalisations.
I can fully explain how all the parts of my answer give a whole picture/ theory.
I can skilfully use numerical data and compare supporting and contradictory evidence to produce a reasoned explanation.
I can apply an abstract scientif ic model in a new context and identify the good points and bad points of the models that I use.
My explanations demonstrate an exceptional level of scientif ic understanding which I can apply in a range of unfamiliar contexts.
I can make connections between explanations and ideas in other relevant areas of science which were not previously being looked at.
I can skilfully use complex models requiring a high level of scientif ic understanding and explain the strengths and limitations each.
I can use a simple diagram to help me describe.
I answer in paragraphs with scientif ic words mostly used correctly.
I can use a labelled diagram to help me explain
I answer in logical paragraphs with correct use of the expected scientif ic vocabulary.
I il lustrate my explanations with annotated diagrams
I write logically structured answers with correct use of complex scientif ic terminology.
I refer to diagrams in my text using them to support my explanations.
I write extended logically structured answers with skilful use of scientif ic language.
I use diagrams & text imaginatively to explain.
Explaining Supporting Communicating
I use simple scientif ic ideas to help me describe
I answer in full sentences and attempt to use scientif ic words.
I can crit ically evaluate the quality and reliability of evidence used to support an explanation and draw a conclusion based on the strongest evidence.
