辅导案例-PHYS1110
Report As part of PHYS1110 you need to produce a report about the physics behind an everyday phenomenon of interest to you. As part of this report you will need to construct an investigation that demonstrates the physics behind the phenomenon. In order to help you produce the best possible report there are four parts to this task. Before 9 PM on 27/10/19 you need to make a post on your group discussion forum about the topic you plan on doing for your final report. The post needs to include your Aim, a brief method and identify the dependent and
independent variable(s) in your experiment as well as any variables you intend to keep constant. Your tutor will give you feedback to help you improve your plan. This post will contribute 1% of your mark for the subject. You will need to submit this report to your peers for marking on 03/11/191 at 09:00 PM. Your peers will provide you with feedback that you can use to improve your report before submitting the final version. You will be required to give feedback to five of your peers (9% of your final mark for this subject will come from the quality of the feedback you give your peers and the completeness of the report you submit). Your feedback is due at 9 PM on 10/11/19. You will then submit the final version of your report through Turnitin by 24/11/19 (at 09:00 PM), to be marked by your tutor. This mark will form 20% of your final mark for the subject. Some phenomena that you may be interested in investigating are listed below. It is best if you choose something you find interesting, you are encouraged to choose something which is not on this list. Remember that you will need to be able to come up with equations and a practical investigation in order to investigate some aspects of your chosen phenomenon:
• The melting of the north pole (what is the latent heat of water?)
• Oscillating masses on springs or rubber bands (what is the spring constant?)
• Different objects rolling down slopes (what effect does rotational motion have?) This should not be a repeat of the friction experiment.
• How do boats sail into the wind?
• How does your favourite musical instrument work?
• Are you able to predict the range of a projectile? There is some free software available, Tracker, https://physlets.org/tracker/ which allows you to analyse the motion of an object from video footage. A video 1 Note: due to the way the peer review tool works it is not possible to get an extension on this deadline. Please be very careful not to miss it as if your report is not uploaded at this time you will not be able to take part in the peer review exercise and so will not get 9% of the marks for this course.
of how to use this software is available here: https://www.youtube.com/watch?v=La3H7JywgX0 . This can be very helpful for any experiment involving motion such as with projectiles or measuring masses oscillating on rubber bands. There are a few topic you may not choose:
• Any of the topics covered in the investigations ie:
o The specific heat of water
o Measuring coefficients of static friction (kinetic friction is fine)
o Measuring the speed of sound with resonance in tubes (other methods are fine)
o Measuring the refractive index of water
• The three topics covered in the sample reports:
o Measuring acceleration due to gravity with a pendulum
o Measuring the pressure when brewing by using the height a liquid rises up a tube
o Modelling Fohn winds with thermometers in the bathroom Some things to keep in mind when you are choosing your topic:
• You should come up with something very specific. Some of the topics above are very general, such as the greenhouse effect. If you are interested in this you need to research it a little and decide on one aspect to investigate in relation to this issue. A possibility for this topic is to look at how the melting of ice caps would effect the heating effect of reflected light. The sea is dark in colour while ice looks white. Does water heat at different rates on a dark background to on a white background?
• Choose a topic for which you can actually perform the investigation. You need to personally have access to the required equipment to complete your investigation. You can only borrow the equipment used in the other investigations from the physics office (scales, measuring jug, kettle etc.) so do not design an experiment that needs specialised equipment.
• Read over the rubric before you pick your topic to ensure that you can address all the points on the rubric by studying that topic.
• You may choose something not on the list but you must first check with your tutor on your group discussion forum to ensure that it is a suitable topic. It is a good idea to start communicating with your tutor early about the topic you want to do.
• Make sure that your investigation covers the physical principles behind your chosen topic rather than chemistry, biology or another science. The final report will be marked by your tutor using the rubric below. You must
include a selfie of yourself with the equipment or your report will not be
marked. Your face must be clearly visible. If you have plagiarized any of the information the minimum penalty you will receive is zero marks for the report. Plagiarism will be investigated and an appropriate record made of the details. You can read about plagiarism here: https://student.unsw.edu.au/plagiarism. The report should be about your own, independent (ie. not done with another student, the method needs to be your own as well as the collected data and everything else in the report) investigation written in your own words. If you
have performed the earlier investigations with a partner you must ensure that you and your partner select different topics for the final report.

Rubric: If your report does not contain a selfie clearly showing your face and the equipment you used you will receive zero marks for the final report.

Less than three references used and/or not appropriately cited in text and given in incorrect format
2 Note: Turnitin does not count the number of words the same way as Microsoft word does. Turnitin counts everything (references, appendices, tables etc.). You can upload your report to Turnitin early and replace it if you want to see the Turnitin word count (click on the information button in the bottom left to see the number of words). This mark is to reward concise reports, it is much harder to cover all the other points with less words. 3 Information about how to cite sources can be found here: https://student.unsw.edu.au/referencing any referencing style is fine.
