This is a lesson that was taught to year 7 and has KS3 levels 4-6. The learning objectives slide promotes AFL and regular checking of progress in lesson - see my other resources for an explanation. I used a visualiser to demonstrate the flower dissection to the class using Lillies. Feedback to rowan.savage@hotmail.com.

This is a worksheet on applying the work done formula (work done = force x distance) with questions and answers. It uses formula triangles to make the content accessible for lower ability students. The final two questions are more challenging as students need to convert from kiloNewtons to Newtons. The conversion is given at the bottom of the sheet.

This is a worksheet on atom economy and percentage yield for GCSE chemistry (grade B+) that is printed as A4 handouts on atom economy and percentage yield. There are three reactions that all make Magnesium sulphate (Epsom salt) as the useful product and so atom economy can be compared along with issues such as toxicity of waste products or reactants. The YouTube video shows how Epsom salts are used in the garden. The formula for atom economy is included. The answers are not yet included and will be uploaded shortly. Please leave feedback if this is useful or if it can be improved.

This is a revision lesson on the group 2 metals and group 7 halogens. Please rate this resource and leave feedback.

This Excel spreadsheet contains links to 48 fun and engaging science videos that are hosted on YouTube. These may be used for countdown timers, engaging starters or as instructional videos to accompany a main lesson activity. The spreadsheet can searched using a keyword for the topic that you are interested in. I have all of these downloaded to a hard drive (approximately 3GB of data) and am happy to make copies of these so please get in touch using my TES inbox.

This covers naming of compounds (e.g. iron chloride) and some challenge questions such as where the heavier elements are made (supernova). Please rate this resource and leave feedback.

This is an AS Chemistry lesson on the group 2 metal compounds and their reactivity and solubility at grades C to A. For grade C students write symbol equations. Note that the hydroxides and sulphates show opposite trends in solubility. For grade B they consider the aluminium sulphate Camelford water poisoning in Cornwall and write ionic equations. Note that all ions are aqueous and that Barium chloride and aluminium sulphate are soluble compounds. For grade A they analyse different data and use this to explain trends in solubility of group 2 compounds. For an engaging starter you could show the reaction of potassium with water and ask students to predict how the reactivity of group 2 metals would be different (less owing to increased charge density and 2 ionisation energies to make the ion). Please rate this resource and leave feedback.

This is a loop game made of 18 separate questions to help revise and understand acid, base and pH calculations as part of A level chemistry - for example in OCR A Chemistry module F325. This makes for an engaging plenary in lesson. I write the equations up on the left of the white board as they are read out and refer back to them in lesson. If there are any suggestions for improvement or general comments please leave them.

This is a lesson plan for multiples to be taught to year 7. The learning objective slide aids assessment for learning and is printed to be stuck in student books. Many interesting real life applications for the lowest common multiple are used to stimulate and develop students learning. Feedback to my TES inbox please.

This is a lesson on using oxidation numbers to determine if a reaction is a redox reaction, disproportionation reaction or symproportionation reaction (opposite of disproportionation). Symproportionation is included to develop understanding and is not required by AS Chemistry specifications. The starter is the engaging visual elephant toothpaste demo. Answers on slide 17 are colour coded and animated. I have another lesson on TES where students calculate oxidation numbers. Please rate this resource and leave feedback.

This is a GCSE chemistry tarsia for revision of rates of reaction. I suggest that the A4 tarsia is printed on card and then the outline is cut out. Students can then quickly cut out the individual triangles. Included are the following topics: symbol equations, factors affecting rate and rate graphs. The 'fjsw' file can be opened and modified with tarsia software.

This is a GCSE chemistry tarsia for revision of history of the periodic table. I suggest that the A4 tarsia is printed on card and then the outline is cut out. Students can then quickly cut out the individual triangles. Included are the following topics: nationality of Dobereiner, Newlands and Mendeleev, law of triads, law of octaves, atomic number, gallium, number of natural elements and number of elements known to Mendeleev, grouping of the elements. The 'fjsw' file can be opened and modified with tarsia software that is free to download. Please note that the software does not work on Mac computers.

This is a fun GCSE chemistry tarsia for revision of combustion. There are 16 triangles with 18 pairs of questions and answers that make a parallelogram. I suggest that the A4 tarsia is printed on card and then the outline is cut out. Students can then quickly cut out the individual triangles. Included are the following topics: formulae, complete combustion, incomplete combustion, carbon neutral, products of combustion. The software is free to download but there is not currently a version for Mac computers.

This is a fun KS3 chemistry tarsia for acids and alkalis. There are 16 triangles with 18 pairs of questions and answers that make a parallelogram. I suggest that the A4 tarsia is printed on card and then the outline is cut out. Students can then quickly cut out the individual triangles. Included are the following topics: indicator, pH meter, pH of different substances, formula of HCl and water. The software is free to download but there is not currently a version for Mac computers.

This is a KS3 chemistry tarsia for revision of elements and compounds. I suggest that the A4 tarsia is printed on card and then the outline is cut out. Students can then quickly cut out the individual triangles. Included are the following topics: number of atoms in a molecule, number of elements in a compound, definition of elements and compounds.

This is a fun yet challenging GCSE Chemistry tarsia for comparing different theories of atomic structure. There are 18 triangles with 21 pairs of questions and answers that make a kite shape. I suggest that the A4 tarsia is printed on card and then the outline is cut out. Students can then quickly cut out the individual triangles. Included are the following topics: names of scientists such E.R. Rutherford and J.J. Thomnson who played important roles in developing atomic theory, isotopes, electron shells and the periodic table, charge on subatomic particles and comparisons of the main models.
