Chance to spend two weeks at CERN this summer!

New summer camp for high-school students at CERN

S’Cool LAB Summer CAMP is an opportunity for 22 high-school students (aged 16-19) from all around the world to spend 2 weeks exploring the fascinating world of particle physics. The first S’Cool LAB Summer CAMP will take place from 23 July to 5 August 2017. 

If you  want to spend their summer at S’Cool LAB, CERN’s hands-on particle physics learning laboratory, for an epic programme of lectures and tutorials, team research projects and visits of CERN’s research installations, please visit the S’Cool LAB website to learn more about the camp, and how to apply. 

COver work for Ms Hamnett

Dear Y12
Apologies for not being in today, for cover I would like you to;
Complete the work on Isaac Physics
Finish your "My favourite particle" presentation for tomorrow - needs to be 1 page poster and at least one minute of speaking
Make notes on the standard model and how it fits together, plus its limitations
Revise all work on particles covered so far this year ready for a mini test tomorrow
Thanks
MS H

Creation and Annihilation homework

Please complete the second question sheet from today's lesson.

Again A-level club for help etc.

Due Wednesday 12 October.

Project homework for Dr Hardwick

Research your chosen Scientist.  Find out about their work on particle/nuclear/quantum physics.  Wikipedia is a good start.

You presentation should be a maximum of 10 minutes long and a minimum of 5.

You should include:

• A brief background of the Scientist (education etc)
• What relevant thing to particles they discovered
• How they made their discovery (experiment, theory etc)
• What other scientist's work they used/built on to make their discovery.
• Any other relevant info.

A short powerpoint would be great which can be emailed to me at dha@cheney.oxon.sch.uk or brought in on a memory stick etc.

Of course A-level club is always here on Tuesday's after school for help!

12a work for Ms Hamnett - Friday 30th September

Finish your particle top trumps cards , adding the lepton number, baryon number, strangeness and symbol for each one, plus any missing charges - DON'T ADD THE MASS (different units will mess this up).  Some of this info will be on your formula sheets, other info you will need to look up.
Don't worry about what the words mean - we will look at this next lesson.
Complete the questions set on Isaac Physics
Both are due next lesson (Thursday 6th October)
Thanks 
Ms H

Can you access this blog?

A test to see who has actually looked at this blog
A photon is going through airport security. The security staff asks if he has any luggage to scan. The photon says, "No, I'm traveling light." ...

A Level club (Physics) this week

Hi 12b,

Due to staff training this Thursday, neither Dr Spence nor Ms Hamnett will be available at A Level club this week.

Dr Casson will be there, and can help with any queries etc.  She's also happy to help with revision timetables etc - you just need to ask.

Alternatively, I am happy to help with revision timetables this Friday lunchtime - just come along to W10 and grab me.

Please do not leave it until after half-term to sort out your revision plan!

12b cover work - 17th May 2016

Hi 12b (James' class),

I'm really sorry I'm not in today.

In my absence, please go through the Work, Energy, Power powerpoint I've uploaded on Edmodo.

You should then complete every 3rd question in Chapter 3 (Work, Energy, Power) of Practice in Physics (p.21 onwards).  Bring your worked answers to next week's lesson.

With thanks
Dr Spence

12d cover work - 17th May 2016

Hi 12d (Coral's group),

So sorry I'm not in today.  In my absense, please:

1) complete your research into measuring acceleration due to gravity (find two experiments, explain how they work, compare and contrast them)
2) Find and complete an exam question on any mechanics topic on this website (http://www.cyberphysics.co.uk/interactive_syllabus/A_Level/)

You should bring your research and your exam question (and answer) to next week's lesson.

Thanks
Dr Spence

Lesson 1 – Single Slit Diffraction

1.  Watch the video here on single slit diffraction: https://www.youtube.com/watch?v=7CmbItRjM-Y

2.  Draw the pattern for single slit diffraction of monochromatic light. Describe the width of the central maximum compared to the others. How does the width of the central maximum vary with slit separation, slit-screen distance and wavelength (write a formula)?

3.  Research the appearance of white light diffracted from a single slit. Draw what pattern appears. Challenge: Can you explain why this occurs?

Lesson 2 – Optical fibres

12b Ms Hamnett work for Monday's lesson

Dear 12b
As mentioned on Thursday, no lesson period 5 Monday.
Work to do and bring to Thursday's lesson;
Research and make at least 2 pages of notes on how diffraction gratings work and how they are used to determine what distant stars are made from and what the atmosphere of exoplanets may be made from.
Research and make notes, with references, a method for determining the wavelength of light using a double slit, light source, filters and a screen.  Include details of all measurements needed and how to make the results accurate and minimise errors.
This will be checked on Thursday.

12d work for Tuesday 1st March

Dear Y12;

My apologies, I'm away today.  Luckily, you've watched this week's video, so you're all set to work independently.

I've taped some question sheets to my door, but I've also posted it in Edmodo.

Once you've finished the work, please revise Internal Resistance and EMF (Yes, this is an electricity topic); we'll be revisiting this on Thursday

There is a also new video on Educanon that you need to watch before our lesson next Tuesday.

Enjoy!
