    Hi OMG, I have been teaching IB Physics for years. You can definitely do your experiment at home. Here are a few short videos to help you choose a topic. The example I use in the videos is based on an experiment that can be done at home. Let me know if I can help in any other way Take care and all the best, Peter from the PaperPlainz Team
  2. Hello November 2020 IB Physics students! Our team at PaperPlainz.com created this calendar to help you save time and energy when getting ready for your IB Physics exams. The calendar is attached and here is a short Youtube video with helpful tips on how to maximise the use of this calendar. Enjoy Peter from the PaperPlainz Team November 2020 IB Physics Revision Calendar.pdf
  3. Hello, I am not sure where exactly your strengths and weaknesses lie, but I would probably get started with Maths and Physics. Maths, because there is a clear list of expected, prior knowledge that you should have before entering a course (just search IB Maths AA Guide and you will find a document with lots of details) and Physics, because even though there is no clear prior knowledge there, it is super-important to have a strong foundation in some of the basics (if you took IGCSE Physics and did well, you should be in a good shape). Once you covered the prior knowledge in Maths and revised some Physics, you can even start looking at the syllabus and revising parts that you have learned already (for example, the sine and cosine rules are in the Maths AA syllabus, but most people have learned these before entering IBDP). A challenge I see in these two subjects with new IBDP students is that exam-style questions are different and more complex than in MYP or IGCSE, so a next step could be to find past exam questions in these subjects online and start looking through their structure and wording. At the end of each guide (Physics and Maths) you will find a list of command terms that repeatedly come up on exam questions, so another good use of your time is to familiarise yourself with these words (no need to memorize their meaning, just be aware of what they mean). Finally, calculator: get really familiar (if not already) with some features of your Graphic Display Calculator (usually TI-84 or Nspire, maybe Casio). Just type IB Maths HL calculator skills into Google and you will get various documents. I hope this helps, it is awesome that you are already looking ahead and trying to prepare. It will help you a lot during those two busy IB Years.
  4. Sure, happy to help This looks fine to me, the only thing to change would be to make sure your line passes through the origin (it is a bit off and it seems that your horizontal axis intercept is around 0.5). Take care and keep up the good Physics work!
  5. I see. Sometimes your line of best fit will not be a straight line and it is okay. In this case the line of best fit, as you wrote earlier, is a curve. When you draw it, just keep in mind the general guidelines for line of best fit: 1. Draw it so that it passes through the first and the last point. 2. It passes as close to the data points as possible. Does this help? If you would like to take a picture of your solution post it here, I will be happy to look at it. Take care and have a great day!
  6. Hello, I have a few ideas. Do you think you could post a screenshot of the question here? It will be easier to help that way.
  7. Hi Dom, since you are verifying an existing value (as I understand, you are aiming to confirm through a simulation-based experiment, the value of Wien's displacement constant), you would not formally state a research question (since you already know the value you should get). You can form a hypothesis, stating that based on the existing scientific context, you should get approximately 2.897771955...×10−3 m⋅K for this constant. Then you can carry out the experiment with the temperature as your independent and the wavelength as your dependent variable. A thought of caution though: this experiment is one of the examples in the Teacher Support Material provided by the IB. In general, carrying out the exact same work as in the Teacher Support Material examples is not recommended as it puts you in a higher risk of plagiarism and probably lowers your chances of getting a good mark on personal engagement. There are many other constants (see data booklet) that you can verify and that might be more interesting. Does this help?
  8. Hi Zia, 1. You can use a slow motion camera to figure out the terminal velocity. I would probably do it this way: 1. Film the falling filter in front of a measuring tape so that you can see on the footage the distance fallen by the filter. 2. On the footage, find the section where your filter is not accelerating any more. 3. Play the video for one second. The distance fallen during this time is basically your terminal velocity in m/s. 2. The height is one of your control variables, so keep it the same. 3. Your research question has the basics, I would probably add in a bit more context about the equipment, etc. A few days ago we added an Internal Assessment section to our IB Physics website and the questions you are asking are answered in the section that is free of charge. You can check out the website here: https://paperplainz.com Just go to the IA section and you will see. I hope this helps Good luck! Peter
  9. Hello IB Physics Students, We are excited to share with you our newest addition: The complete, step-by-step, simple-to-use PaperPlainz IB Physics Internal Assessment Guide! To give you even more support with your IA work, we also launched the PaperPlainz Facebook IA Community where you can ask questions, clarify doubts and most importantly support each other during the IA process. Click here when you are ready to join Just a reminder that our offer to give full access, free of charge to all PaperPlainz resources to schools that are closed due to the COVID-19 situation is still open. If your school is closed, just ask your Physics teacher, Sciences Head of Department or DP Coordinator to send us an email to [email protected] and we will get back to them with details. Take care and stay safe! The PaperPlainz Team
  10. Hello IB Physics Students, Our team at PaperPlainz.com decided to provide temporary full access, free of charge, to all of our resources to support your online learning during the COVID-19 school closures. If your school is affected, please ask your IB Coordinator, Science department head, or Physics teacher to send us an email to [email protected] for details. Looking forward to hearing from your school! The PaperPlainz Team
  11. Hello IB Physics Students, We are currently working hard to make our new IB Physics website even better and we are looking for website testers Would you like to get free access to all resources on PaperPlainz for three months? In exchange, we only ask you to let us know if you spot something that you think we can improve on. Interested? Send us an email to [email protected]! Peter from the PaperPlainz Team
  12. Thanks, I am glad to hear that! If you run into any trouble with anything regarding the site, please feel free to let me know. I would really appreciate it.
  13. Hello sunsally, thanks for letting us know and I am sorry for the inconvenience. Does the website load slowly or do the videos take time to start and play? Have you tried again? If yes, how was it? If it is still slow, please let me know so that we can look into fixing it. Thank you Peter
  14. Hello, I have been an IB Physics teacher for several years and I started creating videos for my students and for my Physics website (PaperPlainz.com). I started uploading some of them on Youtube and I just wanted to let you know that you can watch them here. I am continually working on videos, practice questions and other IB Physics materials, so keep checking for new resources from time to time. Have a nice day, Peter
  15. Hello IB Physics Students, I am an IB Physics teacher with over ten years of teaching experience. IB Physics is challenging, difficult and can be very frustrating at times. My goal is to help you on your IB Physics journey any way I can. As part of this mission, I am starting a blog on the website that I recently opened (https://paperplainz.com). A few examples of possible blog post topics are: Top tips for scoring well on your IA. The most common definition-type questions that appear on Paper 2. How to create an effective study calendar (including resources) before you exams? As you see, I have some ideas about blog post topics; however you are the people who know the best what it is that you really need and would like to read/learn more about. Please take a moment to drop a comment and let me know what you would like me to write about in the upcoming posts. Thanks and hope to hear from you soon Peter Kovacs
