Unit Structure
Unit Structure
Strand 1: communicating data
Developing international conventions for recording and communicating data enables global collaboration..
Inquiry questions:
What examples do we have to support the need for global agreements on units? (F)
How does scientific communication differ from other forms of communication? (F)
Why do we need global agreements on units? (D)
Does the SI system improve global engagement? (D)
Strand 2: validity
Precise measurements, with clear uncertainties, establish the validity of concluding statements.
People act on scientific conclusions that cite the validity of experimental data.
Inquiry questions:
How can collaborators understand the precision of our measurements? (F)
How do we summarise the precision of multiple data points? (F)
How can we calculate the experimental uncertainties of a proportionality? (F)
How can we know as critical thinkers if a statement is valid? (C)
Why do we need to communicate the limits of the validity of our data? (C)
What are the benefits of international conventions in communication? (D)
Approaches to Learning :
Approaches to Learning :
Research - Collect, record, and verify data (with a focus on gathering data with instrumental uncertainties)
Research - Process data and report results (with a focus on reporting processed data in graphical form)
Applications and skills:
Applications and skills:
Present numbers and quantities in standard form to a required number of significant figures.
Demonstrate how to convert between unit prefixes.
Demonstrate an understanding for the instrumental precision (uncertainty) of different equipment.
Design data tables that clearly distinguish between raw and processed data.
Calculate experimental uncertainties.
Design appropriate graphs to to answer the original question.
Analyse graphical results, including identification of random and systematic errors.
Assessments:
Assessments:
Summative assessment - test will be conducted after unit 2 as a combined units 1 and 2 test.
Formative online quiz (15 min) assessing significant figures, units, and conversions (AS 1-2).
Formative task - graphing instrumental uncertainties (AS 3-4, 6).
Formative task - graphing experimental uncertainties (AS 3-6).
Summative task - Hooke’s Law (AS 1-7).
Summative assessment - the skills from this unit will also be assessed in practical work throughout the year, contributing to grades in every unit.
