Subject description This subject provides an introduction to motion, waves and optics, thermal effects, properties of solid and fluid matter, electrical and nuclear concepts, with a view to developing an appreciation and understanding of how to describe and model the physical aspects of nature. The material is presented with particular focus on applications in the medical, biological and environmental sciences. The subject integrates, as key components, hands-on laboratory work and the analysis of experimental data.

Subject learning objectives (SLOs) Upon successful completion of this subject students should be able to: 1. recognise principles and laws of physics most relevant to current and future studies in a range of disciplines including biomedical, medical and environmental sciences 2. apply physics concepts to a range of bio/medical/environmental science-type problems. 3. demonstrate effective scientific communication skills (including report writing, poster presentation, semi-formal oral communication), in a laboratory context 4. maintain a faithful record of work carried out in the laboratory. 5. design and modify experiments requiring the application of basic physical principles to a variety of context-rich situations. 6. apply methods of analysis of experimental data 7. develop quantitative and qualitative approaches to problem analysis requiring equation manipulation, the use of appropriate units, an appreciation of the influence of experimental error and consideration of correct orders of magnitude 8. access information from a variety of sources including the Internet and the library. 9. demonstrate the capacity to work independently against deadlines.

(3.0) An understanding of the different forms of communication - writing, reading, speaking, listening - including visual and graphical, within science and beyond and the ability to apply these appropriately and effectively for different audiences. (6.0)

Contribution to the development of graduate attributes This subject contributes to the development of the following: Graduate Attribute 1 - Disciplinary knowledge and its appropriate application. Graduate Attribute 2 - An inquiry-oriented approach Graduate Attribute 3 - Professional skills and their appropriate application Graduate Attribute 4 - Ability and motivation for continued intellectual development Graduate Attribute 6 - Communication skills

Teaching and learning strategies Lectures: 2 hours per week for the whole session Practicals: 2.5 hours per week Workshops: 2 hours per fortnight on average Online assignments Other student support resources are available, including UTSOnline Discussion Board and U:PASS. Students will adopt collaborative learning strategies in the inquiry-oriented laboratory sessions. Learning will be facilitated through active participation in a variety of hands-on and inquiry-based activities. Lectures and workshops are seamlessly incorporated into this subject. Online resources such as Youtube and simulations will be used to supplement pre-prepared materials which students will read before attending a lecture, workshop or laboratory session. All assessment items within the lab and workshop programs (for example, log books, poster, report, skills test and workshop exercises) are supported by feedback to students. This feedback is given continuously throughout the session. WebAssign is used and this gives students immediate feedback on each attempted question. The only assessment for which feedback is not given is the final exam.

Task:

This assessment task has four components: Skills Test - 8% that provides a means of determining whether students can perform the processes and skills required in laboratory work. The test requires the completion of practical exercises as well as answering questions related to experimental science (such as data analysis, graphing and calculation of uncertainties). Laboratory Report - 10% that requires students to integrate the scientific approach to experimentation in a formal manner by using a format consistent with discipline norms to describe experimental procedure, collation of results, analysis and conclusion. Poster and Presentation - 5% that requires students to reflect on their experiences and focus on the main themes. It is a good way for groups to describe and explain their work. A verbal presentation accompanying the poster gives students practice in presenting and justifying ideas using appropriate general or technical language. Prelab and Log book - 7% that requires students to complete designated pre-lab exercises before commencement of each lab session. Students are also required keep an accurate record of experimental activities in their log book.

Due:

Practicum period; see Further information

Criteria:

Assessment in the laboratory programme consists of the following elements: 1. Skills test, a practical examination conducted during a practical class. It requires the completion of some practical exercises, as well as answering questions related to the laboratory work (such as graphing and error calculations). Access to the log book during the test is permitted (but not the laboratory manual). 2. Laboratory report, based on the 2-week solar cell experiment. This is an authentic assessment task mirroring the practice of science and scientists. Each student is required to submit an individual report (i.e. not a group report). 3. Poster and presentation, based on the Ultrasound 2 experiment. Students are required to reflect on their experiences and focus on the main themes of the experiment. A verbal presentation accompanying the poster gives students practice in presenting and justifying ideas using appropriate general or technical language. 4. Prelab and logbook, requiring students to complete designated prelab exercises and keep an accurate record of activities in each practical session. Maintaining a logbook is a requirement of many practicicing scientists. Guidelines and rubrics for laboratory reports, posters and other aspects of laboratory assessment are provided in the laboratory manual and the Resource book.

Further Prelab and Logbook: in each practical class information: Skills Test: in your practical class during the week beginning 28 August 2017 Lab Report: in your practical class during the week beginning 25 September 2017 Poster and Presentation: in your practical class during the week beginning 9 October 2017
