IYPT Australia
Extended Experimental Investigation 2017
Problem Selection:
All students must see their teacher to nominate their chosen problem and name their partner (if appropriate) by:
Friday 6 October
Mandatory Draft:
Students should prepare a draft copy of their assessable extended experimental investigation report (a single copy for pairs). The draft report should be submitted electronically, with a declaration of independent work by 8.20am on
Friday 27 October
In the subsequent lesson, students without drafts will not be able to continue their research as they wish. Instead they will sit and prepare a handwritten draft (unless there is a spare computer available) and submit it at the end of that lesson. Unless exceptional circumstances arise, this document will be marked if the final presentation is not submitted on time on the due date.
Experimental work completion:
The experimental side of the EEI must be completed, laboratories tidied and all equipment returned by 3.10pm on
Friday 3 November
Length:
A length of 800 to 1000 words applies to the discussion/evaluation/conclusions
ecommendations sections of the report. The body of the final report should be a maximum of 10 pages, not including photographs and appendices
Submission Date and Time:
The report must be submitted by 8.20am to the box outside the Science Staffroom on
Friday 17 November
(Submit earlier in the week if not able to hand in on day)
For students who are working in a pair, a copy should be submitted for each member of the pair (ie 2 copies in total).
Independent and Original Work:
On submission, you must sign a declaration stating that the report is independent and original work. For those working in pairs this means it should be independent of other groups working on the problem. Students sometimes submit work that shows evidence of collusion with other students or plagiarism. In such cases, teachers will assess only that part of the submission that is identified as the student’s own work. It is School policy that all students knowingly involved in the submission of plagiarised work will be penalised.
Request for Extension:
An extension may be granted in special circumstances on application to the Head of Physics, Mr Allinson, via their teacher. Students should submit their application at least 2 days prior to the due date unless an extraordinary circumstance within 48 hours of the due date necessitates the request for extension. Students may apply for one extension only for any set task.
Presentation:
Format: All assignments are to be typed with a suitable font (e.g. Times New Roman or Arial); a font size of 11 or 12; a line spacing of 1.5 or 2; and suitable margins.
Cover page: The cover page is to be attached to the front of the assignment and should include: ID number for that subject, class, topic, teacher, due date, date handed in.
Binding: All pages are to be securely attached to each other using a staple.
Referencing: The school has adopted the APA system of referencing as its standard. Where appropriate, a bibliography should be attached to the back of the assignment.
Folders: The report should be submitted with your journal and video tape/photographic evidence in a single A4 plastic sheet protector. Do not use folders.
EEI Task 2017
You are required to select an open-ended research task and then conduct an extended experimental investigation into then problem.
You need to develop a theory that explains the phenomena that occur in your chosen problem. It should “tell the story” and clearly show “Senior Physics” concepts such as force, motion and energy transfer. It should not be a reproduction of higher order physics that you do not understand!
Your theory must be in a testable form and you must conduct experiments that collect quality data that you can use to test the truth of your theory.
Conducting extended experimental investigations is “doing science” and the open-ended nature of the problems you investigate is very important.
The EEI you undertake will challenge you to investigate a phenomenon and seek a physical explanation of what you observe. It will almost certainly not lead to a simple answer. You will have to plan the activities you wish to undertake to make significant progress.
The development of the understanding of the physics behind a phenomenon is an ongoing process and is not the result of a single person.
STEP ONE:
Decide to work independently or in a pai
STEP TWO:
Select a problem
STEP THREE:
View the phenomenon!
STEP FOUR:
Start researching
STEP FOUR:
Design your experiments and conduct a risk assessment
Select one of the following from the IYPT 2017:
esearch ONE of the following 7 problems:
1. Dancing Coin (IYPT Problem 3)
Take a strongly cooled bottle and put a coin on its neck. Over time you will hear a noise and see movements of the coin. Explain this phenomenon and investigate how the relevant parameters affect the dance.
 
2. Drinking Straw (IYPT Problem 5)
When a drinking straw is placed in a glass of ca
onated drink, it can rise up, sometimes toppling over the edge of the glass. Investigate and explain the motion of the straw and determine the conditions under which the straw will topple.
 
3. Conical Piles (IYPT Problem 7)
Non-adhesive granular materials can be poured such that they form a cone-like pile. Investigate the parameters that affect the formation of the cone and the angle it makes with the ground.
 
4. Cusps in a Cylinder (IYPT Problem 8)
A horizontal cylinder is partially filled with a viscous fluid. When the cylinder is rotated around its axis, unusual fluid behaviour can be observed, such as cusp-like shapes on the walls of the cylinder. Investigate the phenomenon.
 
5. Candle in Water (IYPT Problem 9)
Add some weight to a candle such that it barely floats in water. As the candle burns, it may continue to float. Investigate and explain this phenomenon.
 
6. Blowing Bu
les (IYPT Problem 15)
When blowing on a soap film in a ring, a bu
le may be formed. The liquid film may pop or continue to exist. Investigate how the number of bu
les produced from a single soap film and the characteristics of the bu
les depend on the relevant parameters.
 
7. Water Bottle (IYPT Problem 17)
The cu
ent craze of water bottle flipping involves launching a partially filled plastic bottle into the air so that it performs a somersault before landing on a horizontal surface in a stable, upright position. Investigate the phenomenon and determine the parameters that will result in a successful flip.
These problems are sourced from the 17 problems of IYPT2018  @ http:
iypt.org/images/f/f1/problems2018.pdf
You are required to keep a daily journal of your work and produce a written report of your findings.
The Written Report
You should remember that the Extended Experimental Investigation is the one area of your assessment profile where the criteria for Investigative Processes and Evaluating & Concluding are given the major focus. The body of the final report should be a maximum of 10 pages, not including photographs and appendices.
Structure of the written report:
· Cover page
The cover page is to be attached to the front of the assignment and should include: ID number for that subject, class, chosen problem, teacher, due date, date handed in.
· Abstract
The abstract is a paragraph written at the completion of your work. In about 200 words the abstract outlines what you did and what you found out. You may have seen abstracts when searching for documents during previous research tasks. The information contained helps the reader decide if the article is worth reading or worth purchasing.
· Theoretical
This section should be where you explain the physics of the phenomena you are investigating. It may explain how forces and/or energy transfers create motion or the observed effects. New concepts may be introduced that you have discovered from your research and sources should be have full citations. If possible, the theory should lead to mathematical models that allow you to make clear hypotheses for your experimental work.
These research problems are deliberately open-ended. Within your theory, you will need to explain why you chose to pursue the direction taken in your investigation. You may need to refer to your initial observations of the phenomena and state assumptions, definitions and simplifications in order to make the problem manageable.
· Experimental
You will have conducted experiments to collect data to support your theory. In this section you explain the designs of your experiments and then what you found out. Start with clear testable goals or hypotheses. Try to include calculations, graphs and analysis. You may wish to put the most important detail here and refer to others in an appendix.
· Integration of theory with experiment
A length of 800 to 1000 words applies to the discussion/evaluation and conclusions
ecommendations sections of the report. This section may link the analysis conducted in your experiments with your theoretical explanations. It will include comparisons between experimental and theoretical equations and considerations of uncertainty and e
or. What did you find out?
· Concluding Statement
You need to summarize your findings and, like any conclusion within a scientific experiment, you need to link back to your aims and hypotheses. What are your findings, “your solution” and since an investigation doesn’t really end, what are future directions for the research.
IMPORTANT: Evaluation & Concluding
This is a very important element of the EEI – Use your journal to review each experiment and draw conclusions AS THEY ARE CONDUCTED – this will make it easier to write your final report.
As part of the scientific process in conducting your EEI you will be:
· required to search for prior discoveries in your area.
· required to design and conduct experiments to collect valid data (precision and accuracy)
· encouraged to discuss your ideas and detail these discussions in your journals
· expected to share your findings with the scientific community.
· You are required to work in pairs or on your own (no groups of 3).
· A single written report of the investigation is produced - if in pairs, then both students should identify the sections produced by each individual.
· A daily journal must be kept by each student and stamped by your teacher after each lesson.
· Photographic and video evidence should be included to show your ownership of the work.
Conducting Experiments
Before conducting any experimental work a risk assessment of the activity must be conducted.
When conducting your experiments, it is important to realize that other groups will also be conducting experiments and you need to work with consideration. Sudden noise, light or activity may ruin other peoples’ results.
· The laboratories and Sequester Room must be left in a tidy fashion at all times. Other classes use these rooms.
· Any request to leave equipment assembled for later use must be addressed to your teacher and cannot

Running Header: Parameters that will affect the formation of a cone
Title: Parameters that will affect the formation of a cone
Presented By:

Date: 25/10/2017
Preface
In variety of applications, it will be required to formulate a cone from the non-granular materials. The typical formulations of cone like pile will also depend on the factors like adhesiveness and non-adhesiveness of the materials as well will also depend on the actual cone geometrical parameters as well. The following part of the discussion will focus on these elements of the formulation that will affect the cone formulation. Typical factors considered for study are the adhesiveness of the particles, particle sizes, angle of repose etc. The findings and the discussion presented in the report will be used for the setting the particle sizes and the funnel sizes in the related experimentations.
Discussion:
Particle Shapes:
Angle of repose or the angle of the heap will depend on the particle size of the elements that makes up the heap. It can also define as the steepest angle or the angle of the dip at the sideways at which the actual particles start sliding down. This angle can be anywhere from 0 to 90 degrees. The angle of repose will depend on the particle shape and the interparticle friction as well. If the particle has more number of corners, the angle of repose will be decreased. At the same time if the particle do have elongated sides the impact of the particle shape on the angle of repose will be suppressed and this in turn will depend on the inter particle friction. As the coefficient of friction increases the angle of repose also will increase to some extent, there after the angle of repose will saturate and subsequently the angle of repose will start decrease. At the point of saturation, the rotation and the coefficient of friction will compete as the causes of motion of the particles(El shou
agy,2005).Fig-2 indicates the impact of the number of corners on the angle of repose, however the impact of the elongation interms of the suppression of the effect on angle of repose can also be seen in the figure.
Gravity effect on the angle of repose:
The angles of repose of the granular material will depend on the gravity impact as well. In the case of low gravity substances the static angle of repose will increase and the dynamic angle of repose will decrease. However the findings are reported for the particle sizes ranging from 0.2 mm to 2.4 mm and the particles are both smooth spherical as well are angular particles as well. Further there is usage of air and water as interstitial fluid. Further at the level of planetary surfaces it is expected that lower dynamic angles of...
