Low demand task looking at determining the missing mass of reactants/products in a series of equations. Suitable for Foundation tier candidates, or as in introduction to conservation of mass for Higher tier candidates. Would also make a good homework/recap. Answer sheet included. Powerpoint slide with animated answers also provided.

A worksheet where the electron configurations need to be drawn for atoms of 12 different elements (from within the first 20 of the periodic table). Also requires element symbol to be completed, number of electrons and “shorthand configuration” (e.g. 2,8,5). Single sheet of double sided A4. Useful summary/homework/starter/plenary/revision sheet.

Worksheet with a selection of equations showing reacting masses. Pupils need to calculate Mr to work out the number of moles and then use these numbers to balance the equations. Explanation boxes at the top of the sheet assist in class and serve as a prompt if this is given as a homework.

Short animated PowerPoint showing a simple, but logical step by step approach to calculating relative formula mass. Presentation also includes a set of questions followed by the answers.

Element properties research task. 35 nets to produce a cube, each with a different element symbol. Relatively low demand - find atomic number, mass number, uses, appearance of element etc. This has worked well for me as a cover lesson where pupils complete the info on each face of the cube, or as a homework task. Little chance of copying within a class with 35 different elements! It would be easy to add more if necessary. Effective when hung from the ceiling when complete!

Low demand revision task for Atomic Structure and the periodic table. First slide of the PowerPoint can be printed as a worksheet (large print on A4). Second slide is animated with the answers. Useful as a revision task/starter/homework.

A set templates for teaching/practicing ionic and covalent dot & cross diagrams. The set contains templates for 5 ionic substances (NaCl, NaF, MgCl2, BF2 and LiCl) and 7 covalent substances (CH4, NH3, H2O, CO2, HCl, CL2 & O2). Each template contains 4 copies on one A4 sheet (each will be A6 size when printed and cut) and all have the correct number for shells for each atom. Both types of template can be annotated with dots and crosses. The ionic template also has space to show the charge on each ion and a space to write the equation.

I use this sheet when introducing the atom at the beginning of GCSE Chemistry. The intention was to have one sheet where all of the important information could be found. It also requires very little student input (and could be edited to require even less!), allowing them to focus on a key idea in Chemistry. The only student input required is: adding labels for the nucleus and shells (I use the white space to the right of the diagram to do this) and completing the table at the bottom.

Short PowerPoint showing the steps involved in calculating relative formula mass.Questions + answers at end of presentation.

Short PowerPoint illustrating how to calculate rate of reaction from both results tables and graphs. Note: final slide is designed to be printed and given to students to annotate while viewing and discussing the first two slides.

A double sided A4 sheet of short summary questions on C1.1 Fundamentals, C1.2 Limestone & C1.3 Metals. Useful as a homework/revision/cover lesson.

Short PowerPoint explaining and illustrating the Mole with questions and answers to try.
