what is a band 6 student - hsc physics
DESCRIPTION
Presentation given to students to help them succeed in HSC PhysicsTRANSCRIPT
BoS Background
0 Current Standards set in 2002
0 Band descriptors are set to describe the MIDDLE of the band
How do I get 90?
0 Not about perfectly meeting the Band 6 descriptors
0 It about ‘Tipping the scales’, so that you are more like Band 6 than band 5
HSC ‘Judging’
0 Not only are examinations marked, they are also ‘judged’ against criteria to determine which ‘band’ a student and their responses falls into
0 Judges build an image of what a borderline student looks like
0 You must show the judges that you belong in Band 6 rather than Band 5
Knowledge and Communication Descriptors
Band 5 0 demonstrates a thorough
knowledge and understanding of the concepts of the physics course content including context, prescribed focus areas and domain
0 effectively communicates a detailed understanding of physics concepts using appropriate physics terminology and some illustrative examples and applies the concepts to unfamiliar situations
Band 6 0 demonstrates an extensive
knowledge and understanding of the concepts of the physics course content including context, prescribed focus areas and domain
0 displays an outstanding ability to describe and explain physics concepts, including abstract ideas, clearly and accurately, and to apply the concepts to unfamiliar situations
0 communicates succinctly, logically and sequentially using a variety of scientific formats
What do these terms mean?
0 Unfamiliar (Q1)
The engine of a remote controlled plane of mass 25kg provides a constant force of 400N.
This plane is put into a vertical ascent for 5 seconds until the engines cut out. If the initial vertical velocity is 15ms-1 and the ascent begins 20m off the ground, determine the maximum height reached by the plane.
What do these terms mean?
0 Unfamiliar (Q2)
Whilst playing tennis, Jono serves a carrot with a velocity of 45ms-1 at an angle of 6.5degrees below the horizontal.
The height of the carrot as it leaves his stick is 2.45m above the ground. The net is 12.2m away and is of height 0.92m.
Determine whether the carrot clears the net.

2009 HSC
Theories and experiments not only help increase our understanding but also generate new questions.
Use the standard model of matter to support this statement.
Band 6 students need wider reading than just a text book
What do these terms mean?
0 Succinctly, Logically and Sequentially
0 Get to the point little extraneous information
0 Your answer should ‘flow’ A causes B which causes C etc..
0 If you use a diagram to illustrate your answer, you MUST draw your diagram before you start explaining it!
Language, Communication and Style
0 Clear, precise and accurate usage of Physics terms
0 Uses pictures, equations, graphs, tables
0 Relate their answer to the question, not just factual recall
0 Answer STRUCTURE
Language, Communication and Style
0 You must provide an answer which has a strong foundation
0 Identify
0 Describe
0 Explain
0 Analyse
0 Assess
0 Link
If you are asked to assess, you must work up to it

Importantly
0 You do not have to be 100% correct to gain 6/6 or 8/8 in a high mark-value question
0 You need to ensure that you tackle the verb correctly and relate your knowledge to the underlying question

0 Does not cover the entire syllabus 0 PFAs
0 Skills
0 Values and Attitudes
0 Struggle to see links 0 Unfamiliar situations
0 Multiple outcomes
0 Twist question to knowledge rather than twist knowledge to question
SKILLS
0 A student obtaining a Band 6 can still be dropping 20+ marks (2010: 75 90)
0 Focussing on recall of information will not gain these marks
0 Must focus explicitly on skills which are being ‘taught’
Band Descriptors - Skills
Band 5 0 analyses information given in
written, tabular, graphical and diagrammatic forms and relates this to other relevant information
0 displays competence in manipulating equations to solve problems involving a number of steps
Band 6 0 applies a high level of critical
thinking skills in developing appropriate solutions to problems involving a long sequence of related tasks
0 analyses, evaluates and extrapolates data effectively, identifies complex relationships, quantifies explanations and descriptions, and synthesizes information to draw conclusions
Ub3r Band 6 Question (Q4)
An English essay is thrown at an angle of 60° above the horizontal.
It takes 4 seconds to pass a point which is 80m above its launch height and returns to this launch height after a further 9 seconds.
Determine the acceleration due to gravity acting on the essay and maximum height which the essay reaches. (Ignore air resistance and violence to essay)
