This practical gets students to measure the rate of reaction when a thiosulfate solution is mixed with hydrogen peroxide. The resource includes a brief background to the experiment, a sheet to record data and some instructions for the Technician to help make up the solutions. This resource can be used for younger students to improve their experimental technique and interpretation and graphing skills (leave out the chemical equations) or for A2 Cambridge, Honors or AP students who wish to measure more detailed reaction kinetics. Some errors were found and have since been addressed (2016) Key words: kinetics, reaction rate, collision theory, iodine clock reaction, experiment

These activities were developed to help native Chinese students learn the English words for the elements of the periodic table. Our lessons are slower than in the typical timetabled class. I found that these worksheets helped the students gain confidence in the spoken and written word as well as learn about the periodic table. Over a 2 week period and many practical activities there was a significant increase in their communication and general engagement in the classroom. This resource bundle includes a funworder where the student must find the element (and atomic number) based on the Chinese word; two worksheets which require the student to fill in the English word or the Chinese word and a cross word puzzle. Answers are included. I am not a native Chinese speaker but have had the resources checked by a native speaking Chinese student. If there are any errors please get in touch and I will make the appropriate changes. I would also like feedback as I have a series of resources I will be publishing in the coming weeks. Your feedback will help direct my focus.

This resource consists of 4 problems in which the student has to work out the % of different compounds in a mixture. They are challenging and would suit mathematically strong students who are enrolled in Honors, AP or who want to compete in the National Chemistry Olympiad competition.

This resource consists of notes and worked examples to show how to establish a molecule's Lewis structure and molecular shape. The problems are more difficult than ws1 and would suit students who are doing Honors, AP or are interested in competing in the National Chemistry Olympiad competition.

This worksheet has 2 pages of problems (and answers) which require a Lewis structure and a molecular shape. Some of the questions ask students to compare molecule bond angles and explain why they differ. A set of notes with examples is included. This resource would be useful for students enrolled in Honors or AP.

This work sheet has a series of unknowns (a-o) that are either a reagent or a product. The reactions are limited to oxidation, reduction, nucleophilic substitution, chlorination, cyanation and addition reactions. The worksheet will suit students enrolled in Honors, AP or with an interest in the National Chemistry Olympiad competition. Answers are included.

This experiment gets students to compare pH titration data collected using different indicators. It shows the importance of choosing the correct indicator. The experiment(s) are easily carried out in 50 minutes and students can do up to 8 titrations during the class. Data is reported back to the teacher and the results shared with the wider class. Student feedback suggests this is a very useful practical and the repetitive nature of the experiment allows them to fine-tune their experimental skills. The practical will be useful for those studying acid-base chemistry and buffer systems. Students enrolled in Honors and AP courses would find this practical beneficial. Notes for the teacher are also included Key words: buffer, acid-base, equivalence point, buffer zone, practical, pKa, indicators.

This resource consists of three double-sided works sheets with over 45 questions and worked answers. Each problem requires students to either calculate the number of moles, mass, molecular mass or % composition. This resource would suit those learning to use n = m/M for the first time. With all the best intentions in the world, mistakes do get made. Please tell me if there is an error and I will correct it and organise to send you a corrected copy.

This resource consists of a 4 page problem booklet (and answers); a very brief set of notes is at the start of the booklet. The problems include some short answer questions (eg relating to Boyle's or Dalton's laws) and some calculations. The booklet would suit students doing AS or IB chemistry courses.

This resources contains 5 pages of problems (2 double-sided wrk sheets) that include * Alkanes: name and / or draw isomers * Alkenes: naming and/or draw isomers, organic transformations and geometric isomer problems. In the latter case students are asked to work out how many isomers are possible for a compound with multiple double bonds). This worksheets will suit students studying for AS or IB organic chemistry. they can be sued as 2 sided w/s or as separate w/s as starters. Answers are provided.

This resource will be useful for teachers new to the profession or those with limited experience teaching chemistry. It contains * notes for the teacher including a 4-6 period lesson plan and template for practicals (5 pages in total); * a simple power point presentation with 13 slides that gives step by step instructions on how to balance equations. Reactions are limited to group 1 and 2 metals and their associated oxides, hydroxides and carbonates; * 4 worksheets (and answers) for word, symbol, and also word and symbol problems. The worksheets (and answers) can be found as separate resources if notes and lesson plans are not required.

This resource consists of some general REDOX notes, which outline how to balance REDOX equations and 2 double sided worksheets (and answers). The exercises include oxidation number elucidation, balancing half equations and balancing full equations. This resource would suit students who want to progress in the Honors program.

This resource consists of some general REDOX notes, which outline how to balance REDOX equations and 2 double sided worksheets (and answers). The exercises include oxidation number elucidation, balancing half equations and balancing full equations.

This resource consists of 5 pages worth of problems containing spectra for 14 compounds. Typically, a molecular formula is given along with 3-4 spectra and the student is then expected to reason using the number of peaks and the signal position which spectra belongs with which structural isomer. This resource would suit students doing A2 or other advanced Chemistry courses. All attempts have been made to ensure the answers are correct. Please get in touch with me if you find an error and I will address it and send you an updated version.

This resource consists of 2 worksheets and answers. It covers definitions, short answer questions and calculations (solubility products, solubility, common ion effect).
