school closure work for Higher class

We’ve been looking at the photoelectric effect this week.  In this video, Professor Dave reviews some of the points we covered in class.

Click on the picture below to download a simulation to investigate the effect of irradiance on frequency on photocurrent.  You’ll be prompted to install Java if you don’t have it already.

Once the animation is running, you can;

  • change the metal under investigation (we used zinc in class)
  • vary the wavelength of the incident light
  • vary the irradiance of the incident light.

Notice that below the theshold frequency you can’t get any photoelectrons, even if you set the light to its brightest setting.

Compare your results to the graphs provided in your notes.

I have attached some notes & questions on the photoelectric effect. Click on the link below to download a copy.

S3 snow day work

I have uploaded a set of notes on the Using Electricity unit.  Please click on the download link below and save a copy on your computer at home.  I would like everyone to read up to the end of page 19.  This will cover everything that we have looked at so far on this topic.

Please try to answer as many of the questions in these notes as you can, either by printing out the pages and writing in the spaces or using your Physics jotter.

You may leave a comment if you get stuck with anything and I will try to help.

5.3 snow day work – past paper questions

We worked on some past paper questions today and I would like you to try these at home if you were unable to make it to school.

The attached pdf file contains 2 past paper questions.  The first question is Q24 from the 2008 paper, the second is Q25 from 2007.  Please attempt both questions. If you get stuck, leave a comment on this post and I will get back to you.  Next time you are in school I will hand out copies of the specimen solutions for you to check your progress.

5.5 snow day work – past paper questions

We only had 6 people in class today due to lack of school buses.  Those who made it in asked to do revision questions, so we worked through the 2010 Higher paper.  If you couldn’t get in today, please download the paper by clicking on the link below.

I would like you to attempt the following questions;

  • Q24 (all)
  • Q25 part (a) only
  • Q26 parts (a) & (b) only
  • Q27 (all)
  • Q28 (all)

This will cover a good section of the unit 3 work you have been looking at with Mrs. Sutherland as well as the unit 2 material you have covered in my class.  Remember you have booklets with worked solutions but please only use once you have finished or are stuck and can’t get any further without help.

Add a comment to this post if you have any questions.

snow day work for S4

If you can’t get to school due to the weather, here is some work for you to do at home.  We will start the Transport topic when we have finished our Investigations.  Please use these notes to begin looking at the Transport unit.

Read the notes on average and instantaneous speed and try the questions.  If you have a printer at home, please also try to print out the pages with squared sections to practice drawing speed-time graphs.

Click on the download link below to get the file – you will need Adobe Acrobat Reader.

higher snow day work – part 2

The weather forecast says we could be in for loads of snow later this week so I have uploaded some more work for you to do if you can’t get in to school or we end up having to close.  Please continue to work through the unit 2 notes I uploaded last week but these unit 1 notes are worth looking at if you have finished the 2nd unit.  You may not be able to answer all of the questions (such as the acceleration section) without some experimental results but just move on to the next section instead.

If you have any questions, just post a comment and I will get back to you.

Snow day work for Higher Physics

I have attached a link for you to download some notes on Unit 2 of the Higher course.  Both Higher sets will be able work up to page 15, covering work we have already looked at in class.

5.3 should then work through pages 18 & 19 in preparation for the next section of unit 2. You have new homework – see the entry further down this page.

5.5 – you can also work through the Wheatstone Bridge activities on pages 20-25.

Snow day work for S3

If you can’t get to school due to the snow, here is some physics work so that you can keep up with the course.

We started looking at Ohm’s Law last week. Go to the HelpMyPhysics site and try the Ohm’s Law activities there.  I have also uploaded some additional problems taken from our classroom booklets.
