Week 2: The Maths Bit

Week 2: Significant Figures

You will need to be able to use and understand significant figures in N5 Physics. Don’t worry if you don’t get it straight away, we’ve almost a year to get it right. The video I’ve found is clearer than I could do and sorry it is a bit long, but well worth getting to grips with. What I will add today is a document explaining the importance of significant figures to a physicist, which I will post on here and in the class Notebook section. I wouldn’t watch the hour long video as we need to move on.

  • Watch it here on Youtube : Significant Figures Video
  • Read  and make notes on significant figures: It is in Class Notebook, and on Mrsphysics
  • Read and make notes on Rounding (Sheet to follow)
  • Make sure you’ve checked the answers to the Compendium Questions on Significant Figures. (section 0)
  • I’ll add to the calculator work this week, and you can work through that as soon as you can.

Week 2, part 2. Rounding

You will need to correctly round to the correct number of significant figures in N5 Physics. Again you might not get it straight away, but you’ll get plenty of practice. I’ll do another helpsheet for the Class Notebook.

  • Watch the video on Youtube: Rounding in more detail  it explains the reason for rounding and how it does it
  • For an additional help try this one Rounding Videos This is by the same guy who did the sig fig video.
  • Make notes on rounding: it will eventually be in the class notebook and on MrsPhysics in the N5 maths section.
  • Complete the Sig fig and Rounding Quiz (10 questions). You ought to be able to get at least 7/10. Review the work if you get less than this.

Scientific Notation Week 2 extension

…..but you will need to be able to do this. You will need to know how to do Scientific Notation. I will not test you in this just now, but you should be confident about it by August. Watch this video on YouTube:  Scientific Notation

Make a note on Scientific Notation in your Class Notebook

There will be a sheet this week to help you with this, which will be in the class materials here and in your note book as well, and on this site in the Maths bit.

Week 1: Intro to N5

Focus

  • Know what to expect on the National 5 Physics course
  • Understand the Course Structure
  • Know where to access materials
  • Find good places to go for online help.
  • Know about Units, Prefixes and Scientific Notation

Success Criteria

  • Understand the make up of the SQA N5 Physics Course
  • Get 90% or more on the weekly Friday Review assessment
  • Complete the tasks on Units, Prefixes and Scientific Notation to a high standard

TASKS

  • Check out the National 5 compendium and save your own copy in an editable form.
  • Read through the whole of Mrsphysics.co.uk/n5 front page
  • Go through the compendium and mark off the content that you feel you have already covered in BGE. You could do this electronically if you want (NB Capital P in wingdings 2 gives a nice tick and capital O gives a cross).
  • Check through the course content from the SQA website
  • Watch Mr Mitchell’s Introduction to N5 Physics
  • Watch Mr Mitchell’s Greek Letter Video
  • Watch Mr Mitchell’s Video on Units, Prefixes and Scientific Notation
  • Read the material in the Intro of the Compendium.
  • Make notes on the Compendium content 0.2,0.3,0.4. and pages 21 to the end.
  • Work through material on rearranging equations
  • Answer the questions from the Learning Outcome Question Booklet on Units Prefixes and Scientific Notation 0.2, 0.3,0.4 or if you need the link as a pdf
  • Start making a list of Quantity, Symbol, Unit, Unit Symbol, Scalar or Vector in the Notes. NB Colum 3 needs to be much wider than most and column 1 needs to fit in gravitational field strength, but columns 2, 4 and 5 only need to be a few letters wide. Keep this up to date, and we’ll have a quiz as to who can get the longest list from all the quantities you’ve met in the BGE.
  • Do the Quiz on TEAMS- you’ll need to score 9/10 or more so do some revision.
  • Let me know if you don’t have a CASIO 83 or 85 calculator.
  • ….and finally, ask any questions that you have or anything that you need to be explained in more detail.

WELCOME TO THE TEAM.!
