Feel free to post any predictions, especially for them 6 markers! feel free to share what is most likely and unlikely to come up on Friday's paper!

goodluck for Friday.

Can someone please post the most important notes because my teacher hasn't even finished the physics gcse chapter with us yet and I'm so eff'd

just remember:
specific heat capacity
you need know them calculations
diffraction, reflection, refraction
learn the specification
learn everything possible basically just to be on the safe side

I have mine too, hopefully we both do well
good luck

Thank you
Last night I studied Part A and tonight I' going to study part B
I wish you good luck

try going through a lot of the main topics

Electricity generation
Red shift
Evaporation, radiation, convection, conduction
Specific heat capacity
Calculations
general knowledge about Waves

6 marker could be about the national grid and how it works.

6 marker could be about the national grid and how it works.
6 marker options:
National Grid - possibility given there wasn't much on it in P3
Solids, Liquids, Gases - extremely unlikely (maybe a 2 marker?) as P3 had a 6 marker on them
Conduction/Convection/Radiation - maybe
Vacuum flasks - maybe
Animal adaptations/Insulating homes - possible although hasn't been seen in the past few years
Doppler Effect/Big Bang - extremely likely because there was no mention of stars in P2&P3 and stars almost always appear...somewhere!

My weak areas are remembering all of insulating homes/vacuum flasks. Any tips for remembering them (I know it's late!)?

DCLOTH (Sounds silly I know)

D - draught proofing- foam/plastic around doors to sop droughts of cold air = convection

C - cavity wall insulation - foam between bricks in wall to stop convection currents being set up = radiation, conduction and convection

LO - loft insulation - thick layer of fibreglass wool laid out = conduction + convection

T - thick curtains - big cloth over window = conduction + radiation

H - hot water tank jacket - material that provides heat for water tank e.g fibreglass wool = conduction + radiation

after the = it tells you the ways in which heat lost is reduced. I don't know if you'll find this helpful but it helped me XD

Good luck guys i have an exam too xx
How hard do you think this exams going to be? Or will it be easy like the chem exam? Ffs scared

Predictions are:
Cost of electricity
Payback time
U-Values

6 markers-
Energy
Renewable energy
Energy transfers
Big bang

Everything else:
Waves - doppler
red shift
sound
electro magnetic

aaaaand sankey diagrams

Vacuum flasks came up in 2013 so they're unlikely to come up as another six marker

Maybe something like how power stations generate electricity including how energy is transferred to produce electricity to enter the national grid and step up and step down transformers?

What type of question would come up for a 6 marker question on the big bang... kinda my weak point

Also what features are there on a vacuum flask.. my revision guide gives:
Vacuum (reduces radiation,Convection& conduction)
Shiney surface on inside(reduce radiation)
Cap is plastic filled with foam
Held by insulating foam

Also how does cavity wall insulation stop convection and how does CMBR prove the big bang theory
Thanks if you can reply... GOOD LUCK

If there is a 6 marker on em waves what would it be and what would you put? Hoping its on the Big Bang though!!

It's likely to be on the evidence to prove it etc like cmbr and red shift I will give u a perfect answer in a minute if you like?
