This resource consists of 2 worksheets: 25 calculation problems (and worked answers) involving aspects of acid base chemistry and some general pH calculation notes, which initially cover simple calculations. . The first half of each work sheet covers pH calculations in both acid and base conditions and calculation of H+ and OH- ion concentrations. The 2nd side of the worksheets focus on pH calculations involving partial neutralisation reactions where the student has to work out what species is in excess before calculating the pH. Some problems also involve the use of n=m/M equation. These problems would suit students doing IGCSE, year 11 chemistry or wanting to enter the National chemistry Olympiad competition. ps (June 2018) I have updated this resource and changed a problem that potentially is misleading.)

This resource contains two double sided problem sheets (and answers). The first is a series of punnet square focused problems and the 2nd asks students to interpret and answer questions from two pedigree charts. Both also contain some short answer questions. It will suit students who have not studied Genetics before. Key words: homozygous, heterozygous, dominant, recessive, punnet squares, zygote, chromosomes, pedigree charts. Thank you to everyone that bought this resource. If you get a spare 2 minutes could you leave some feedback? It is the only way I will know whether it meets your needs or what I might need to do to develop it further. My students want me to make up some more similar-styled worksheets, which I will load in the near future.

This bundle of resources is suitable for students studying Ecology (age 13-15 years old). It covers terms such as food chains, food webs, habitat, niche, symbiosis, trophic levels, predator- prey relationships, scavenger, parasites, producer and decomposer. The resources included are: * A two page checklist of all the learning objectives * Activity 1: a 10 min. exercise to match terms and words * Ws1 and ws2 require students to draw food chains or webs and answer some questions (double sided). There are also some cloze activities included in ws2. * The "food webs" resource can be laminated and used as a class set or the students can cut the arrows and animals out and produce a food web. * The "ecology poster" is a handout (3 per page) given to students who then develop a targeted poster * A crossword puzzle (and answers).

This resource focuses on laboratory equipment found in a typical school. There are four worksheets. The first bundle relates to laboratory equipment that is typically used in schools. The student either provides the English word or the Chinese word. Pictures are given on each worksheet. The answers are also provided. The second bundle relates to words we typically use to describe what we observe in an experiment. It includes terms that are important for drawing and describing graphs. The feedback from the classroom has been very positive and some colleagues from other schools have asked to use these resources for their Chinese International students. If there are specific topics you would like please tell me as it is likely they are currently being developed / or used.

This resource consists of all of the material a teacher would need to teach a 3-4 week topic on this most delightful of topics: the Periodic table. Most of the focus is on the PT trends, how it can be used to predict a property of an element or charge on an ion. The activities have been tried in my class over the past few years and the students feedback and improved grades suggest they add value. My bug bear as a Chemist is that the PT is often taught as "first 20 by rote" with little time spent showing students how they can use the PT to help answer questions or solve problems. The topic covers subatomic particles, electron configuration, formation of ions, compounds/molecules, reactions of group 1 and 2 metals with group 6 and 7 non-metals and the tests for H2, O2 and CO2. Resources include worksheets, cloze activities, starters, projects, identifying equipment activity and short tests. The “notes for teachers” outlines how I teach this subject for both low and higher ability students along with ideas of the projects I set the students. Some documents contain more than 1 worksheet or activity and some worksheets are 2 pages long. Additional slides have been included on balancing equations if the class is stronger. Either use them in this course or save for the following year. Some of this material appears in other resources at Drogchem's shop (eg balancing equations and funworders). Thank you to everyone that bought this resource. If you get a spare 2 minutes could you leave some feedback? It is the only way I will know whether it meets your needs or what I might need to do to develop it further.

This resource consists of 7 worksheets made largely of diagrams that require labeling (heart, lungs, endocrine, digestive and the eye), some questions that require short answers and a cross word. This is that resource you struggle to find: some diagrams that can be labelled and then some questions to follow. This resource would suit a range of students depending on the national curricula (eg. IGCSE).

This bundle has been updated (29 Sept 16) to include: * a 13C nmr spectra assignment worksheet (14 spectra; 5 pages long) and answers to help prepare for the spectroscopy test (see below). * a 1 hour 8-page test (or work sheet). There are 3 questions built up of multiple parts. Each requires the student to use information from Infra Red, Mass Spectrometry and C-13 NMR spectra to elucidate the different compounds. Answers are included. Students are expected to give evidence to support their assignments. This test would be useful for A-level students. Note: This mark scheme is specific to the NZ National examination program and involves some holistic marking and grading rather than /100. The test takes about 1 hr and the focus is on the student being able to write full answers and justify their assignments. It is important that the user adjust this resource to fit with their own national assessment. Over the coming months further tests/work sheet versions will be developed, which will allow users to cut and match questions or be longer to meet end-user needs. The 3rd document consists only of answers (cf. the 2nd where the answers are built into the test/work sheet).

This worksheet has bond enthalpy and lattice energy calculations and would be suitable for A level students. Key words: Hess’s law, bond enthalpy, Lattice energy, calculations.

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 pack consists of material that will be covered in the AS and A2 program. It includes + Power point (53 slides) covering: oxidation number and balancing REDOX equations revision, REDOX calculations, batteries, Nernst equation and electrolysis. + Summarised CIE learning objectives + Student notes - REDOX (8 pages) that summarise the slides + Student notes – balancing REDOX equations + 7 -11 work sheets depending on whether double sided or a booklet (19 pages of problems) and answers. + Practicals (4) Buying this bundle will mean buying material used over two years so hopefully it is save you time and be viewed as value for money. Please note, some of these resources are already available on TES but as smaller bundles. 17 Aug 16: A recent typo was found on the electrolysis w/s and it has been updated (Q4, IV).

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 AS-A2 Cambridge or A level 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 8 worksheets (and answers) that focus on the key words that are used when describing plants: cells, leaves and flowers. There are two versions of each resource requiring either a Chinese word or an English word (usually 1-2 pages of words). There are also resources that require the student to label the diagram using English words. The feedback from the classroom has been very positive and the resources are being reviewed for use in other schools. If there are specific topics you would like please tell me as a number of other resources are currently under development and review.

This resource consists of 6 pages of problems (questions, mechanism and 'complete the reaction scheme' questions) targeting the A2 Cambridge program. Answers are provided. The problems and answers have been checked but if there are any errors or questions, please get in touch with me and I will address them. If you would like a certain type of worksheet please contact me as I am working on other ones for my classes and I will reorder my efforts if I think it can be useful to others.

This resource consists of 5 pages of terms and expressions in Chinese and English that relate to the human body. Separate version require filling in the Chinese or the English word. Additional resources (and answers) specific to the heart, lungs, digestion, the hormone system such as as cross word puzzles, cloze style activities, diagram labeling are also given. Although these resources have been checked by a native Chinese speaker mistakes do happen. Please get back to me if you find an error. The feedback from my international class has been positive and these notes help the students.

This resource will be useful for older Chinese students who have started an English speaking physics program. The material would suit students at AS or A level. The resource includes 3 pages of key radioactivity words in both Chinese and English. These have been created into worksheets where the student puts in either the correct English or Chinese word. Room is made for the student to also write down definitions. One worksheet asks the student to fill in the blanks for a list of words but it is also designed for them to read silently, aloud (eg in pairs or in front of the class). There is also a 15 minute starter focused on sub atomic particles.
