Assignement Task :

Syllabus outcomes assessed

• A student develops and evaluates questions and hypotheses for scientific investigation.
• A student designs and evaluates investigations in order to obtain primary and secondary data and information.
• A student conducts investigations to collect valid and reliable primary and secondary data and information.
• A student selects and processes appropriate qualitative and quantitative data and information using a range of appropriate media.
• A student analyses and evaluates primary and secondary data and information.
• A student communicates scientific understanding using suitable language and terminology for a specific audience or purpose.
   

Context
You have been learning about the trends and patterns in relation to the properties of pure substances. Scientists use this understanding to predict the properties of other pure substances and this allows them to determine how these substances can be separated from each other.

In this depth study assessment task, you will research two substances in more detail by looking at their distinct measurable properties (which includes melting and boiling points, strength and density).

“Depth studies provide opportunities for students to pursue their interests in chemistry, acquire a depth of understanding, and take responsibility for their own learning. Depth studies promote differentiation and engagement, and support all forms of assessment, including assessment for, as and of learning. Depth studies allow for the demonstration of a range of Working Scientifically skills.”    

Nature of the task
This assessment task is divided into two parts:  
PART 1: PRACTICAL INVESTIGATION

You are to conduct a teacher-set practical experiment to investigate the properties of substances. You will be assessed on how you answer the discussion questions provided (these will be submitted with your report).

PART 2: REPORT

This report consists of five sections:

For both of the two substances you have chosen, you will need to hand in the following information:

 A table which identifies information about their physical properties, including melting point, boiling point, type of bonding and at least two other properties (250 words maximum)
 A statement describing the form in which the substance is naturally found and extracted, or how it is produced (250 words maximum for each substance)
 A statement explaining how the physical properties are a result of the structure/bonding (half a page maximum for each substance), plus an appropriate diagram for each substance.
 A statement describing two uses of each substance, linking how its physical properties contribute to its uses (250 words maximum for each substance)

Section III: Research question

 You will develop your own research question about one of your substances, which discusses a development that has happened related to the substance and why this development has happened. For example, has an alternative substance been developed for some reason? Is the substance being considered for an alternate use? You will evaluate the effectiveness of this development (500 words maximum)

Section IV: References

 You are expected to reference all sources according to the Harvard format and hand this in on a separate sheet of paper. You must have a minimum of 4 separate references. 

Section V: Practical investigation handout

 After completing the experiment in class time, you will submit your answers to the discussion questions provided.
