Science Teachers or Science 9-1 Curriculum dabblers, please help!

[user1497126393]

I would just like to ask, based on the numerous articles read and a friend who works in school; apparently around 33% of the schools in England make students as early as year 9 study their GCSE 9-1 Science modules in Biology, Chemistry and Physics.

So my question is- How would this work structurally and strategically?
Would year 9 students for example learn: Module 1 for Biology and Physics and Modules 1 and 2 for Chemistry GCSE?

I guessed this strategy because based on AQA: Bio= 7 modules, Physics=6 modules and Chemistry = a whopping 10 modules and that would make sense.
So then I think year 10 and 11 will split 6 modules (3+3 modules) Bio
5 modules split in two for Physics and 8 modules (4+4 modules) Che

.....just to have the correct foundation of knowledge for this would help me greatly.

Please let me know if I am right or am wrong and if there are errors here tell me.

I have twins who have just started Y10 (at different schools) and they both started GCSE science in Y9.

Both schools allocate students to combined science or triple science at the end of Y9, so in Y9 they started studying the topics that are present in both the combined science specification and the triple science specifications.

DD (Edexcel) studied the following in Y9:

Physics:

1. Conservation of Energy
2. Waves
3. Light & the Electromagnetic Spectrum

12. Magnetism & the Motor Effort

Chemistry:

1. Key concepts in Chemistry
2. Extracting metals & equilibria
3. Fuels & Earth science

Biology:

1. Key concepts in Biology
2. Plant structures & their functions

DS3 (AQA, started GCSE course earlier than DD) studied the following in Y9:

Physics:
P1: Conservation & dissipation of energy
P2: Energy transfer by heating
P5: Electricity in the home
P6: Molecules & matter
P9: Motion

Chemistry:
C1: Atomic structure
C2: The Periodic table
C3: Structure and bonding
C5: Chemical changes
C7: Energy changes

Biology:
B1: Cell structure & transport
B2: Cell division
B3: Organisation & the digestive system
B4: Organising animals & plants
B5: Communicable diseases
B6: Preventing & treating disease
B7: Non-communicable diseases

The chapters I have listed for AQA are from the OUP books. They have grouped the topics differently from the specification, but in approximately the same order.

It’s entirely up to the teacher. aQA publish several scenes/plans but teachers are free to construct their own plan. Most would start off by teaching topics that feature on both combined and single science.

Ds is in Year 10 and I know he studied electricity last year in physics.

The modules aren’t the same size and at least one of the chemistry AQA units is broadly the same as one of the physics units. The course is designed to be equally weighted in terms of content and teaching time.
