PLEASE READ CAREFULLY THE FOLLOWING POINTS before using my OCR Gateway 9-1 GCSE science pages

  1. ALL my unofficial GCSE (Grade 9-1) revision help summaries are based on the NEW 2016 official OCR Gateway Science A (Grade 9-1) GCSE PHYSICS/combined science physics specifications.

  2. Make sure you know whether you are doing separate science OCR Gateway Science A GCSE grade 9-1 PHYSICS OR OCR GCSE Gateway Science A Combined Science physics and double check your exam table from school, college or academy.

  3. Also, make sure you know whether you are entered for a higher tier (HT) or a foundation tier (FT) OCR GCSE Gateway science-physics course, so watch out for the (HT only) 'markers'.

  4. I hope my revision pages help as you get to know my website, its very big and not always easy to navigate, but it is no substitute for making good lesson notes, trying your best on homework questions, studying your textbook, doing past papers of OCR GCSE Gateway combined science/physics for exam question practice and, above all, attentive to your teacher's teaching!

  5. I know from feedback that my gcse science summary revision pages have proved useful but they do not guarantee a high grade, that all depends on you and the factors mentioned in point 4. above. Please note that my GCSE science revision pages are designed to be used for online convenience, so, beware, printouts could be quite long!
  6. It is really important that YOU cross-check, from my web pages, the learning objectives from the syllabus-specification with YOUR own lesson/revision notes and textbooks for YOUR OCR Gateway Science A GCSE 9-1 combined science physics course.
  7. 'Doc b's chemistry' is a big website so the Google [SEARCH] box at the bottom of each index or revision notes page can be VERY USEFUL - sometimes its better than the indexes for finding things!

  8. When it comes to the final exam papers, at that point, YOU ARE THEN RESPONSIBLE FOR THE GRADE YOU ACHIEVE, not your teachers or me or my website (which isn't perfect!), so make sure you are properly prepared!

  9. If there is anything about the website you are unhappy with, or you think there is an error, or you think something hasn't been covered adequately, please politely email me with your query to chem55555@hotmail.com

  10. NOTE on grades: Foundation Tier FT grades 1 to 5  and  Higher Tier HT grades 4 to 9. In terms of old grades the following is an approximate comparison: grades 7-9 (A-A*), 4-6 (C-B), 1-3 (G-D), U (U) (from OFQUAL Jan 2018)

Topic P4 Waves and Radioactivity  

(Revision for OCR Gateway Science GCSE 9-1 Combined Science A, 2nd physics paper Topic P4 "Waves and Radioactivity", papers 6/12)

The 2nd physics paper assesses Topics P4, P5, P6, CS7, BUT assumes knowledge of Topics P1, P2 and P3

P4.1 Wave behaviour

Waves are means of transferring energy and the two main types of wave are introduced in this section: mechanical and electromagnetic. This section considers both what these types of waves are and how they are used. The main terms used to describe waves are defined and exemplified in this topic.

You should have prior knowledge of transverse and longitudinal waves through sound and light.

You should be aware of how waves behave and how the speed of a wave may change as it passes through different media.

You may already have knowledge of how sound is heard and the hearing ranges of different species.

Common misconceptions - although you will often have heard of the terms ultrasound and sonar you may find it challenging to explain how images and traces are formed and to apply their understanding to calculations. You may misinterpret displacement distance and displacement time graphical presentations of waves.

Know and be able to apply the equation:

wave speed (m/s) = frequency (Hz) x wavelength (m)

P4.1a Be able to describe wave motion in terms of amplitude, wavelength, frequency and period.

P4.2 The electromagnetic spectrum   

(Revision for OCR Gateway Science GCSE 9-1 Combined Science A, 2nd physics paper Topic P4 "Waves and Radioactivity", papers 6/12)

Having looked at mechanical waves, waves in the electromagnetic spectrum are now considered. This section includes the application of electromagnetic waves with a specific focus on the behaviour of light as rays and waves and explores the application of other types of electromagnetic radiation for use in medical imaging.

You may be familiar with uses of some types of radiation.

Common misconceptions - you can have misconceptions such as gamma rays, x-rays, ultraviolet light, visible light, infrared light, microwaves and radio waves being independent entities and not being able to relate it as a spectrum. You may struggle to link the features that waves have in common, alongside the differences and how these relate to their different properties.

P4.2a Know that electromagnetic waves are transverse and are transmitted through space where all have the same velocity

P4.2b Be able to explain that electromagnetic waves transfer energy from source to absorber - examples from a range of electromagnetic waves.

P4.2c Be able to apply the relationships between frequency and wavelength across the electromagnetic spectrum.  Investigation of electromagnetic waves on chocolate or processed cheese in a microwave to measure wavelength.

P4.3 Radioactivity 

(Revision for OCR Gateway Science GCSE 9-1 Combined Science A, 2nd physics paper Topic P4 "Waves and Radioactivity", papers 6/12)

In this 'radioactivity' topic the idea of isotopes is introduced, leading into looking at the different types of emissions from atoms.

You should have prior understanding of the atomic model, chemical symbols and formulae.

Common misconceptions - you may tend to struggle with the concept that radioactivity is a random and unpredictable process and the idea of half-life is another area that can lead to confusion. You may find it difficult to understand that objects being irradiated does not lead to them becoming radioactive.

P4.3a Know that atomic nuclei are composed of both protons and neutrons, that the nucleus of each element has a characteristic positive charge.

P4.3b Know that atoms of the same elements can differ in nuclear mass by having different numbers of neutrons.

P4.3c Be able to use the conventional representation for nuclei to relate the differences between isotopes including identities, charges and masses.

P4.3d Know that some nuclei are unstable and may emit alpha particles, beta particles, or neutrons, and electromagnetic radiation as gamma rays. 

Use of a Geiger Muller tube and radioactive sources to investigate activity.

P4.3e Be able to relate these emissions to possible changes in the mass or the charge of the nucleus, or both.

P4.3f Be able to use names and symbols of common nuclei and particles to write balanced equations that represent radioactive decay

P4.3h Know that in each atom its electrons are arranged at different distances from the nucleus, that such arrangements may change with absorption or emission of electromagnetic radiation and that atoms can become ions by loss of outer electrons. Know that inner electrons can be 'excited' when they absorb energy from radiation and rise to a higher energy level. When this energy is lost by the electron it is emitted as radiation. When outer electrons are lost this is called ionisation.

P4.3i Know that changes in atoms and nuclei can also generate and absorb radiations over a wide frequency range. Understand that these types of radiation may be from any part of the electromagnetic spectrum which includes gamma rays.

Demonstration of fluorescence with black light lamp and tonic water.

Topic P5:  ENERGY

(Revision for OCR Gateway Science GCSE 9-1 Combined Science A, 2nd physics paper Topic P5 "Waves and Radioactivity", papers 6/12)

P5.1 Work done  

This topic looks at how energy can be stored and transferred.

You may have prior knowledge of energy listed as nine types but you need to be able to approach systems in terms of energy transfers and stores as well as energy being transferred in processes such as changing motion, burning fuels and in electrical circuits.

You should be aware of the idea of conservation of energy and that it has a quantity that can be calculated.

Common misconceptions: You may have misconceptions around energy being a fuel-like substance that matter has to ‘use up’, that resting objects do not have any energy and that all energy is transferred efficiently. You may also confuse forces and energy.
 

P5.1a Be able to describe for situations where there are energy transfers in a system, that there is no net change to the total energy of a closed system (qualitative only) - know the law of conservation of energy

P5.2 Power and efficiency  

(Revision for OCR Gateway Science GCSE 9-1 Combined Science A, 2nd physics paper Topic P5 "Waves and Radioactivity", papers 6/12)

This topic considers the idea of conservation and dissipation of energy in systems and how this leads to the efficiency. Ways of reducing unwanted energy transfers and thereby increasing efficiency will be explored.

You should be aware of the transfer of energies into useful and waste energies and have an understanding of power and how domestic appliances can be compared.

You will have knowledge of insulators and how energy transfer is influenced by temperature and have an awareness of ways to reduce heat loss in the home.

Common misconceptions that energy can be “used up” or that energy is truly lost in many energy transformations. You also tend to have the belief that energy can be completely changed from one form to another with no energy dissipated.

Know and be able to apply the equation:

efficiency = useful output energy transfer (J) / input energy transfer (J)

P5.2a Be able to describe, with examples, the process by which energy is dissipated, so that it is stored in less useful ways.

Topic P6: Global challenges 

(Revision for OCR Gateway Science GCSE 9-1 Combined Science A, 2nd physics paper Topic P6 "Global challenges", papers 6/12)

This topic seeks to integrate your knowledge and understanding of physical systems and processes, with the aim of applying it to global challenges. Applications of physics can be used to help humans improve their own lives and strive to create a sustainable world for future generations, and these challenges are considered in this topic. In this topic you draw together the concepts covered in earlier topics, allowing a much wider treatment of the subject of physics.


P6.1 Physics on the move  

(Revision for OCR Gateway Science GCSE 9-1 Combined Science A, 2nd physics paper Topic P6 "Global challenges", papers 6/12)

You will use your knowledge of forces and motion to develop their ideas about how objects are affected by external factors. You will develop a better understanding of these external factors to be able to understand how the design of objects such as cars may be modified to operate more safely.

You should be familiar with how forces affect motion of objects, but you will also need to have a good understanding of momentum from a previous sub-topic.

You may already have some knowledge of how vehicles are adapted to increase safety.

Common misconceptions - don't confuse the factors that affect thinking distance and braking distance, thinking that alcohol, drugs and tiredness will affect braking distance rather than thinking distance. It needs to be made clear the distinction between these two terms and that the combination of these gives us the stopping distance.

P6.1a Know typical speeds encountered in everyday experience for wind and sound, and for walking, running, cycling and other transportation systems.

P6.1b Be able to estimate the magnitudes of everyday accelerations.

P6.2 Powering Earth   

(Revision for OCR Gateway Science GCSE 9-1 Combined Science A, 2nd physics paper Topic P6 "Global challenges", papers 6/12)

Appreciate that we are reliant on electricity for everyday life and this topic explores the production of electricity. Consideration will be given to the use of non-renewable and renewable sources and the problems that are faced in the efficient transportation of electricity to homes and businesses. Safe use of electricity in the home is also covered in this topic and you will revisit topics such as power and efficiency.

You should already be familiar with renewable and non-renewable energy sources and have a basic understanding of how power stations work and the cost of electricity in the home, and have some idea of electrical safety features in the home.

Common misconceptions - confusing the idea of energy with terms including the word power such as solar power. Appreciate that higher voltages are applied across power lines and not along them. Another common misconception is that batteries and wall sockets have current inside them ready to escape.

Be able to apply the equation:

potential difference across primary coil (V) x current in primary coil (A) =

potential difference across secondary coil (V) x current in secondary coil (A)

P6.2a Be able to describe the main energy sources available for use on Earth, compare the ways in which they are used and distinguish between renewable and non-renewable sources - fossil fuels, nuclear fuel, bio-fuel, wind, hydro-electricity, tides and the Sun.
