This test is about 1 hours long. It includes questions about calculating oxidation number, observations and balancing half and full REDOX equations. Answers are included. This test would be useful for students doing IGCSE and AS chemistry. 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 contains two fun-worders based around the first 20 elements of the periodic table. In the first fun-worder, the student has to find the element. Each element succeeds its atomic number (find the name and you find the atomic number). The 2nd fun-worder has both the proton number (before the word) and the atomic mass (after the word). The student then fills in the periodic table grid (supplied) in the correct order. Other shorter activities are included: match symbols and names, and electron configuration practice. The students love these activities and it can take a good 45 minutes to complete. It is fun and builds familiarity with the PT.

This test comprises about 45 marks worth of short answer questions (with answers). The focus is on the periodic table, electron configuration, balancing simple word and symbol, equations, universal indicator colors and a few questions concerning the electrolysis of NaCl. 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.

There are 2 worksheets (and answers) as well as notes and worked examples (ws2). The resources would suit students aged about 14-17 years old depending on the course. WS2 is for more advanced students. WS1 has 2 pages of questions where the student has to choose whether a reaction is either endothermic or exothermic, draw and label an energy profile. There are also some simple calculations to determine the amount of energy given off from a known mass of an organic compound. WS2 contains notes, worked examples and 10 problems (and answers) focused on the equation Using q = mCΔT and Hess's law. The problems will be useful for students enrolled in Honors, AP or those who would like to sit the National Chemistry Olympiad competition. The problems are of straight forward to moderate difficulty. 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. Key words: Hess's law, thermochemistry, enthalpy, heat, thermodynamics, calculations.

This resource contains 9 pages of detailed notes and worked examples as well as a 2 2-page worksheets that contains some straight forward to difficult (using a quadratic equation) pH calculations. The detailed notes work though a variety of scenarios and some of the associated misconceptions. The notes would be useful for both new chemistry teachers and students. The problems will be suitable for A level students or those wanting to trial for the National Chemistry Olympiad competition. Other problem worksheets re also available at Drogchem. 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. Key words: buffer, acid, base, acidity constant, pH calculations.

This resource consists of 7 pages of REDOX problems involving all or some of the following tasks: drawing a cell diagram, balancing equations and calculating the EMF of the cell in question. The worksheets will suit students enrolled in IB or A level Chemistry or preparing for a national Chemistry Olympiad competition. Answers are provided as well as general REDOX notes. Key words: REDOX, Chemistry Olympiad, EMF, calculations, cell diagrams, Latimer diagrams. 9Feb18: notes and some worksheet answers reworded.

This resource contains 5 simple experiments that have been successfully used in the laboratory for students aged from 11-15 years of age. The aim, through simple experiments, is to encourage safe working with chemicals and familiarity with equipment. One experiment is based on the use of plastic burettes where students are asked to work out which solution is the strongest (most concentrated). The use of burettes adds the 'wow' factor for budding young Scientists. They will talk about it for weeks to come. The experiments are based around color change with common acids and bases and Universal Indicator. A short set of instructions explaining how to make a home made indicator is also included. The "effect f dilution...." resource helps the students link dilution to colour change of UI. The students like this one because it allows them to practice dilutions and observe colour change.

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 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 resource contains student instructions to determine the vitamin C content of a commercial vitamin C tablet (or a Technician's unknown sample). There is an introduction outlining the different REDOX steps involved in the back titration, a data recording sheet and instructions for the Technician for the preparation of the different reagents. This practical would suit students who are studying REDOX chemistry in AS-A2 Cambridge or A-level courses.

This resource consists of two experiments. The first is the permanganate - oxalic acid titration to standardise the permanagate. The second uses the permanganate solution to determine the concentration o f a solution of unknown concentration of Fe(II). These practicals would suit students in year 11-13 who have experience with titrations and REDOX chemistry. The resource has the template for data collation built into it. The resource is 4 pages long. 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. Key words: titration, oxalic acid, permanganate, iron, calculations, practical

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.

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.
