The Challenge
Your team must create an educational demonstration video to illustrate a Physics concept from a topic in the Sec 3 or Sec 4 syllabus. You must make the concept easy to understand, engaging,
and visually clear for a lower secondary student.

Submission Requirements

  • Each group must submit a 90 s video.
  • Originality: The video must be entirely your own work. Do not reuse videos from the internet or experiments already shown by your teacher in class.
  • Group introduction: At the start of the video, all members must appear on screen to introduce themselves.
  • Demonstration: You must use a real-life apparatus and setup.
    • Note: Animations/drawings are allowed for explanation only, not for the primary
      demonstration.
  • Captions: All speech must be captioned in the video.
  • Balanced participation: Every member must speak in the video, and speaking time should be roughly equal, no single member should dominate the presentation.
  • At the end of video, references and sources should be acknowledged.
  • Project brief to be submitted by the group leader by 9 Mar 2026 (Term 1 Week 10, Monday) for teachers’ approval.

2. Assessment Rubrics (30 Marks)

 

3. Student FAQ

  • Can I use AI to help me?
    You may use AI to brainstorm ideas or simplify your script. However, the final script must be your own work, and you cannot use AI-generated voiceovers.
  • Do we all need to be on camera?
    Only for the introduction at the start. After that, you may choose who demonstrates and who narrates.
  • Can I use a drawing for the experiment?
    No. The demonstration must be a real, physical setup. You can use drawings only to help explain the “non-visible” physics concepts (like force arrows or light rays).
  • What is the time limit?
    90 seconds. You have a 10 second buffer. Going significantly over or under will result in mark deductions.
  • Can we borrow equipment from the lab?
    No. Please source for your own equipment.

 

4. Checklist

  • All members introduced themselves on camera at the start.
  • The video is approximately 90 seconds long.
  • Every word spoken has a clear caption on screen.
  • The physics phenomenon is demonstrated with real objects.
  • The language is simple enough for a lower secondary student.
  • We have all submitted the peer review form.

Advanced Physics Paper (Paper 3)

The advanced Physics EOY Written Paper will be held on the same day as Paper 1 and Paper 2, i.e. Friday, 17 October.

Duration: 50 mins

Time: 1345 – 1435

Format: 30 marks of structured questions.

Topics: (All Sec 3 & Sec 4 Advanced Physics Topics which came with notes)

    • Projectile Motion
    • Circular Motion
    • Gravitational Fields
    • Linear Momentum
    • Superposition of Waves
    • Electric Fields
    • Magnetic Fields
    • Advanced Nuclear Physics

The following list of equations and formulae will be included:

Practical Notes:


This diagram shows the correct use of a clamp to hold a split cork (or split rubber bung in this case). Note how the ruler can be placed against it to measure the length of the string.

 


As can be seen from this image, if the split cork is clamped higher up it is difficult or impossible to measure the length of the pendulum accurately.

 


This diagram shows the correct way to clamp the split cork. When the jaws of the clap compress they will hold the string firmly between the two halves.


Incorrect alignment of the cork. Here tightening the clamp will not result in the sting being held more firmly.

 

 

 

 


When measuring the length of the pendulum we must measure to the centre of the pendulum bob. In this case it would be recorded as 56.7 cm (half way between 55.7 cm and 57.7 cm)

The top picture shows the stand being used correctly. In the lower diagram the bob will not be able to extend beyond the edge of the table.


Correct position to read the length of the pendulum – placing the eye at the level of the bob to avoid parallax error.

The Task

Option 1: Experimental Practical

Design and conduct two (related) small experiments to investigate any suitable physics phenomena of your choice.

You will need to plan an experiment and let Mr Shone know what physics equipment you wish to borrow from the lab – a form will be sent out for this later.

 

Option 2: Research

Choose a topic of suitable difficulty  and suitable depth to investigate on your own.

The topic must not be something we have already looked at (or will be looking at) as part of the Physics / Advanced Physics syllabus.

Some Projects that girls undertook in previous years:

Experimental:

      • Oscillation of Connected Springs
      • Archimedes Principle
      • Circular Motion

Research Based Project:

      • Special Relativity
      • Photoelectric Effect

The Presentation

The presentation must be between 10 – 15 mins and everyone in the group must present.

The Slides are likely to include the following to be covered within the stipulated time:

For Practical Projects

      • Brief literature review (theory)
      • Experimental setup and brief procedures
      • Results
      • Analysis
      • Conclusion
      • Brief reflections and key takeaways

For Theory Projects

      • Detailed literature review (of the topic). You will not be expected to talk on every slide as there is unlikely enough time within the presentation period. Thus summary slides might be useful at points.
      • History of the discovery
      • Background information on the key scientists involved

All presentation will end with a short Q&A session.

 

Rubrics

1A: CONTENT (Experimental Project)                                        {15 marks}

Instagram Content (Physics Lesson for 14-2-25)

Hello!

Apologies, my cough and loss of voice are keeping me away from school again today. I am thus leaving you the following activity which I hope you will find enjoyable and relevant.

Background

At the start of the year Mr Shone started a Physics Instagram account (which I hope you are already following!):

https://www.instagram.com/nanyangphysics

He has posted a few items and will continue to create content, but he would very much like to get input and content from Physics Students  – that’s you!

Task

Create a post that can be uploaded to the NY Physics IG.

Content can be anything you like that you think would be suitable and appropriate for this IG account.

Some suggestions:

  • A worked example to a question that you had trouble with previously,
  • A trick that helps solve tricky physics problem,
  • An image (original) and explanation of some physics in the real world,
  • Explanation of a complex physics phenomena / concept in a way you found worked for you,
  • Use this as a chance to revise a topic you are less familiar with – put together the key concepts / points of a particular topic,
  • History, Life, Works of a famous physicist
  • Or anything else you think would be suitable…

Notes

  • Do try to use images / drawings where appropriate, rather than just text.
  • Don’t use any photos or images that are copyrighted (not your own).
  • I have included the outline templates that I have used – use these to keep the look of the site consistent if you like, but if you’re feeling creative, feel free to design it any way that appeals.
  • Try not to just repeat things that can be found directly in the notes or textbook.
  • Be creative, make your post stand out and appeal to viewers.
  • Target audience is yourself and other secondary school physics studying peers.
  • Don’t squeeze it all onto one “slide” you can upload up to 5 “slides” to create the post.
  • Mr Shone may alter your slides before posting for better clarity or to correct any minor physics misconceptions.
  • The posts will be posted in a random order (about 1 a day)
  • There will be a small prize for the post that gets the most likes!

Submission

Use the following Google form to submit your work:

https://forms.gle/anHg8jj5x2ap9tQm6

File(s) can be uploaded as Word, PowerPoint, etc. (which would allow me to edit them), or finalised image files such as JPG, PDF, etc.

Deadline:

Upload by Wednesday 19 February, 11:59pm.

Any questions drop me an email!

5 minutes before taking a Physics Exam…

You are just about to take a physics exam. Here are the things you should take note of:

  • Read the question!
  • More marks – you need to write more!
  • What words are used in the question? “State” does not expect the same answer as “Calculate”, etc.
  • Try to think which section of the syllabus this question is from. That will help you to recall equations and use appropriate physics words.
  • Remember to show as much working as possible.
  • Are the values given in the expected unit (SI units) or do you need to convert them first.
  • Don’t use abbreviations – write things in full (eg Normal Contact Force,  Clockwise, Kinetic Energy, etc) at least the first time you mention them in a question.
  • A general answer such as “the current will change” will nearly never be awarded a mark. We would be expecting “the current will get larger”.
  • Always write an equation down before substituting (otherwise you’ll never get calculation marks)
  • Give all answer to 2 sig. fig. or 3 sig. fig..
  • Use the value stored in your calculator try to avoid rounding off multiple times.
  • Check your units.
  • Final answers should be in decimal format (not fraction).

The following may also help:

  • It is often good to look through a paper and attempt a really easy question first. This gives confidence and helps you to relax.
  • There is nothing wrong with writing down equations at the start of the exam. Many students do this if they are worried they will forget equation such as v²=u²+ 2as.
  • Fleming’s Left Hand Rule, Right Hand Grip rule, etc are there to be used. Don’t be shy about doing them in the exam venue.
  • “Explain” in physics doesn’t just mean using words. Feel free to include diagrams, equations or graphs if they will help with your explanation.

Exam Date: Tuesday, 10 September 2024

Further details such as lab venue will be emailed to you shortly.

As you are not actually graded on doing the practical, it is the things that you write down that will gain/lose you marks. Please take the following very seriously:

PRECISION

every time you record a reading from an instrument the value must be recorded to the correct precision (i.e. the precision of the instrument.)

Instruments recorded to smallest division on scale:

        • RULER (measures to 1 mm)
        • PROTRACTOR (measures to 1º)

 Instruments recorded to half of smallest division on scale:

        • EVERYTHING ELSE

Digital Instruments where we ignore the last digit:

        • STOPWATCH (measures to 0.1 s)
        • DIGITAL CALLIPERS (measures to 0.1 mm)
        • DIGITAL MICROMETER SCREW GAUGE (measures to 0.01 mm)

Advanced Physics Team-based Investigation Project (TIP)

The TIP will be conducted in Groups of 2 or done individually. (No, I will not make a special allowance for you to be a group of 3!)

The project can be experimental or research based on a physics phenomena.

Both options will require submission of a report (PowerPoint Slides) and a presentation (T3, Week 9).

Complete the following form with details of your project:

The Task

Option 1: Experimental Practical

Design and conduct two (related) small experiments to investigate any suitable physics phenomena of your choice.

You will need to plan an experiment and let Mr Shone know what physics equipment you wish to borrow from the lab – a form will be sent out for this later.

 

Option 2: Research

Choose a topic of suitable difficulty  and suitable depth to investigate on your own.

The topic must not be something we have already looked at (or will be looking at) as part of the Physics / Advanced Physics syllabus.

Some Projects that girls undertook in previous years:

Experimental:

      • Oscillation of Connected Springs
      • Archimedes Principle
      • Circular Motion

Research Based Project:

      • Special Relativity
      • Photoelectric Effect
      • Physics of Flight
      • Physics of  Maglev Trains
      • Doppler Effect & Red-Shift
      • Ionising Radiation
      • Kepler’s Laws of Motion
      • Superconductivity
      • Physics of Black Holes
      • Physics of Star Wars
      • Physics of Rocket Propulsion
      • Orbital Resonance of Astronomic Objects
      • Doppler Shift
      • Wave-Particle Duality

 

The Presentation

The presentation must be between 10 – 15 mins and everyone in the group must present.

The Slides are likely to include the following to be covered within the stipulated time:

For Practical Projects

      • Brief literature review (theory)
      • Experimental setup and brief procedures
      • Results
      • Analysis
      • Conclusion
      • Brief reflections and key takeaways

For Theory Projects

      • Detailed literature review (of the topic). You will not be expected to talk on every slide as there is unlikely enough time within the presentation period. Thus summary slides might be useful at points.
      • History of the discovery
      • Background information on the key scientists involved

All presentation will end with a short Q&A session.

Reposting Astrigue invite email

Dear students,

Astrigue is an annual Astronomy competition jointly organised by the Astronomy Clubs of RI (Year 5-6) and HCI (College). The event is targeted at secondary school students who display a keen interest in astronomy. The event comprises a series of engaging booth activities, project-making and quiz questions that will put participants’ knowledge on astronomy to the test. Through this, it hopes to create an organic environment for like-minded students sharing a passion for astronomy to engage in meaningful conversations on the subject matter. Hopefully the learning experience will allow students to gain fruitful takeaways while enjoying themselves and forging valuable ties among their peers.

Physics Lesson, 2nd & 3rd February

Hi Advanced Physicists!

Sorry that I’ll not be in school today. This means you won’t be able to go to the Physics Lab 4, so please just stay in your class for the Physics lesson.

Please complete the following:

  1. Practical 2 (be sure to attach the paper with pin holes, and the graph). [This should also really be complete by now!]  – can hand this up into my pigeon hole.
  2. Assignment 2: Reflection [you should have enough time to complete this during today’s lesson] I will collect this at a later time. If you find there are questions you can’t do because we haven’t covered the whole topic yet that is fine. However, I think you should be able to do most of it!
  3. Still got free time? Try looking through and completing the rest of the notes on this chapter – I suspect you’ll be able to do much of it yourselves (or by referring to my notes on this website).

Hope to be feeling better and back in the classroom soon!

Mr Shone

Why Study Physics?

What is Physics?

Physics is a  science that deals with the structure of matter and the interactions between the fundamental constituents of the observable universe. In the broadest sense, physics (from the Greek physikos) is concerned with all aspects of nature on both the macroscopic and submicroscopic levels.

Physics is the natural science that studies matter, its fundamental constituents, its motion and behaviour through space and time, and the related entities of energy and force. Physics is one of the most fundamental scientific disciplines, with its main goal being to understand how the universe behaves.

 

 

What is Science?

Science is the systematic study of the structure and behaviour of the physical and natural world through observation, experimentation, and the testing of theories against the evidence obtained.

Science is a systematic endeavor that builds and organizes knowledge in the form of testable explanations and predictions about the universe.

The word science comes from the Latin “scientia,” meaning knowledge.

 

What is the Scientific Method?

 

 

 

 

What is psudeoscience?

May be an image of text that says "Science Willingness to change with new evidence Pseudoscience Ruthless peer Fixed ideas review Takes account of all new discoveries No peer review Invites criticism Selects only favourable discoveries Sees criticism as conspiracy Verifiable results Limits claims of usefulness Non-repeatable results Claims of widespread usefulness Accurate measurement "Ball-park" measurement httsp//a/oteoo http://perceptivereality. weebly. com/"

Charge moving through magnetic and electric fields

The magnitude of the force created by the electric field is given by

FE = Eq

FE = EQ (using the values in this question)

The magnitude of the force created by the magnetic field is given by

FM = Bqv

FM = BQv (using the values in this question)

 

Q could be +ve or -ve.

If Q is +ve, then:

    • the electric field will exert a downward force on Q
    • the magnetic field will exert an upwards force on Q (from Fleming’s Left Hand Rule)

This could still create the motion indicated in the diagram, however FM would need to be smaller than FE.

FM < FE

BQv < EQ

v < E/Q

If Q is –ve, then:

    • the electric field will exert an upwards force on Q
    • the magnetic field will exert a downwards force on Q (from Fleming’s Left Hand Rule)

This could still create the motion indicated in the diagram, however FM would need to be larger than FE.

FM > FE

BQv > EQ

v > E/Q

Which is answer D
