A Science teacher by trade, I've also been known to be found teaching Maths and PE! However, strange as it may seem, my real love is designing resources that can be used by other teachers to maximise the experience of the students. I am constantly thinking of new ways to engage a student with a topic and try to implement that in the design of the lessons.

This revision lesson challenges students to explain the results of an osmosis investigation and to calculate accelerations using 2 equations. The PowerPoint and accompanying resources have been designed to check on the understanding of these two topics as detailed in the AQA GCSE biology, physics and combined specifications.
The lesson contains a range of tasks including worked examples, exam questions and quizzes which will remind students that water molecules move across partially permeable membranes by osmosis and how changes in the mass of a potato can be used to compare water concentrations in the potato and solution. Students will also recall that acceleration can be calculated from velocity-time graphs using change in velocity/time as well as through the use of F=ma.
This detailed revision lesson challenges the students on their understanding of the reactions of acids with metals to produce salts and hydrogen. The PowerPoint and accompanying resources focus on the details of point 4.2.1 in the AQA GCSE chemistry and combined specifications, and time is spent reminding the students that these reactions are redox reactions.
The students are given the general word equation for acids reacting with metals and are challenged to recall how to name the salts according to the metal and acid involved in the reaction. They are reminded that redox reactions involve the loss and gain of electrons and are challenged to identify the substances which are reduced or oxidised in specific examples.
In addition to the reactions of acids with metals, this revision lesson also challenges them to write chemical formulae, balance symbol equations, and to identify the tests for gases.
This is an engaging revision lesson which uses a range of exam questions, understanding checks, quiz tasks and quiz competitions to enable students to assess their understanding of the content within topic 4 (Stoichiometry) of the Cambridge IGCSE Chemistry (0620) specification. The lesson covers the content in both the core and supplement sections of the specification and therefore can be used with students who will be taking the extended papers as well as the core papers.
The specification points that are covered in this revision lesson include:
CORE
Use the symbols of the elements and write the formulae of simple compounds
Construct word equations and simple balanced chemical equations
Define relative molecular mass, Mr, as the sum of the relative atomic masses
SUPPLEMENT
Determine the formula of an ionic compound from the charges on the ions present
Construct equations with state symbols
Define the mole and the Avogadro constant
Use the molar gas volume, taken as 24 dm3 at room temperature and pressure
Calculate stoichiometric reacting masses, volumes of gases and solutions, and concentrations of solutions expressed in mol / dm3.
The students will thoroughly enjoy the range of activities, which include quiz competitions such as “In the BALANCE” where they have to compete to be the 1st to balance an equation and recognise the number of moles involved whilst crucially being able to recognise the areas of this topic which need their further attention. This lesson can be used as revision resource at the end of the topic or in the lead up to mocks or the actual GCSE exams.
Each of the 11 revision lessons included in this bundle are detailed and engaging and provide the students with multiple opportunities to check their understanding of the following topics in the AQA Combined Science course:
Random and systematic errors
Independent, dependent and control variables
Pathogens
Viral, bacterial, fungal and protist diseases
The movement of water molecules by osmosis
Calculating acceleration from a velocity-time graph
Using resultant force and F=ma
Reactions of acids with metals
Redox reactions and the loss and gain of electrons
The properties of waves
Refraction
Control systems in homeostasis
The regulation of blood glucose concentration
Properties of ionising radiation
Detecting radiation based on penetrating power
Half-life
Decay equations
Classification system using kingdom, phylum, class, order, family, genus and species
The binomial naming system
The three-domain system
Chromosomes
The 3 stages of the cell cycle including mitosis
The formation of gametes by meiosis
Mole calculations
Concentration of solutions
Protons, electrons, and neutrons in atoms, ions and isotopes
Bond energy calculations
The rate of photosynthesis and limiting factors
These resources can be used in the final weeks and months before the GCSE examinations or for revision before end of topic tests or mocks.
If you want to view the quality of these resources, download the control of blood glucose, reactions of acids with metals, mitosis and meiosis and radiation resources as these have been shared for free.
This is a fully-resourced lesson which uses exam-style questions, quiz competitions, quick tasks and discussion points to challenge students on their understanding of topics P1 - P4, that will assessed on PAPER 5. It has been specifically designed for students on the AQA GCSE Combined Science course who will be taking the FOUNDATION TIER examinations but is also suitable for students taking the higher tier who need to ensure that the fundamentals are known and understood.
The lesson has been written to cover as many specification points as possible but the following sub-topics have received particular attention:
The size of an atom
The differences between isotopes
Using the half-life in calculations
The 13 recall and apply equations in topics P1 - P4
Electrical circuit symbols
Measuring current using an ammeter
Current and potential difference in series and parallel circuits
Changes in resistance in resistors
Mains domestic supply
Kinetic, internal and potential energy in a system
Calculating specific heat capacity and latent heat
Physical and chemical changes
Conservation of energy
Calculating gravitational potential and kinetic energy
Penetrating abilities of the different types of radiation
In order to maintain challenge whilst ensuring that all abilities can access the questions, the majority of the tasks have been differentiated and students can ask for extra support when they are unable to begin a question. Step-by-step guides have also been written into the lesson to walk students through some of the more difficult concepts such as circuit calculations and rearranging formulae and converting between units.
Due to the extensiveness of this revision lesson, it is estimated that it will take in excess of 3 or 4 teaching hours to complete the tasks and therefore this can be used at different points throughout the course as well as acting as a final revision before the PAPER 5 exam.
This fully-resourced revision lesson has been written to cover the major details of the radioactivity topic that can be assessed in the GCSE Physics and Combined Science (HT) exams. The engaging PowerPoint and accompanying resources contain a wide range of activities which include exam-style questions with clearly explained answers, differentiated tasks and quiz competitions to allow students to assess their understanding and to ultimately recognise those areas which need further consideration.
