Worked examples of the kind of calculations students can expect to face from A* - to very basic Grade E and above, included is............. The use of moles in calculations: gases and solutions Working out the formula of a compound using moles Calculating the percentage mass of each element present in a compound Working out the EMPIRICAL formula of a compound Using balanced equations to predict the masses of reactants and products.

A simple pictorial summary with explanation on the use of bacterial DNA to manufacture the human hormone insulin on an industrial scale.

Diagram showing the hormonal interactions controlling the mentrual cycle. Take from a scan of an OHP drawing I did, many many years ago now, but to my knowledge the science is still the same........ I have also included a JPEG with rhe same detail.

Worksheet for completion. Can be used as part of any lesson looking at the manufatcure of Salts, either as a starter or plenary or homework. Can be edited for differentiation purposes to stretch and challenge the most able.

Simple summary with illustration of the Fractional Distillation column of what happens to the physical and chemical properties of the hydrocarbons condensing at different temperatures ie how the compounds change as they rise up the column and condense as they cool the higher up the column they go with lower and lower boiling points.

Basic summary sheet highlighting the differences between saturated and unsaturated hydrocarbons, focussing on single and double bonds as well as the general formulae.

A printable version of the Periodic Table created in excel. Simply press print and this will print out onto A4.

A lesson originally put together for OCR 21st Century Science C1 (Foundation - weak students) with significant challenge but would be equally applicable for any exam board (AQA, EDEXCEL etc) to illustrate the concept of Cause and Correlation. Observed during inspection with this lesson. Very successful outcome. Potentially dry topic. Use a clearly incongruous link, in this case ice cream sales and hayfever cases lnked to pollen count to illustrate the difference between a 'cause' and a 'correlation'. The graphs for this are in the attached powerpoint. Once the difference has been highlighted, move on to collaborative work in the class with the attached work on nitrogen monoxide levels and hayfever and the instances of asthma in a given area. Graphs to be completed using the data on the sheets and the questions about the completed graphs also to be done. Differentiated starter questions are also attached (D- B grade).

To support literacy across the curriculum and obviously Science in particular here, these sentence construction frames are extremely useful in a number of different contexts. Students find this quite a challenge but do engage with this in an extremely positive manner. A good opportunity for collaborative work. They can be edited for differentiation purposes, with significant challenge for the most able and also access for the weakest/SEND. They have been used very successfully as starters, plenaries, end of topic summaries, revision tools, homework and also extensions and they can be adapted for any topic across the entire curriculum from Yr7 to Yr13. I have attached a number of examples with associated powerpoints to have up on the board as the students attempt the task, including..... Limestone Hydrocarbons, Fractional Distillation and Cracking Radiation Respiratory and Circulatory System The Atom, Reacting Masses and Rates of Reaction Transformers and Power
