This resource has a set of notes with worked examples to explain how to determine Lewis structures, molecular shapes and formal charges. The accompanying worksheet uses these skills to predict shapes and reason the bond angles. Some problems are based on the comparison of two molecules.

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.

There are two worksheets (with worked answers) in this resource. WS1 focuses on word equations and limits reaction to those of oxides, hydroxides and carbonates. Notes are also provided. The intention is for students to get used to the idea of always writing down the salt and that water is the other product. WS2 asks students to balance the symbol equations. The equations are limited to acids reacting with oxides, carbonates and hydroxides. Both worksheets are also part of a larger resource called "Chemistry: balancing equations involving metals and their salts". This resource will suit students learning about balancing equations for the first time.

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. The students love these activities and it can take a good 45 minutes to complete. It is fun and builds familiarity with the PT. Other shorter activities are included: match symbols and names, and electron configuration practice.

This resource consists of two activities. The first requires the students to cut and match the 5 Kingdoms, the definition and a picture (answers are given in the other document). The 2nd activity gets the students to cut out some descriptors and organisms and group them into different phyla.

This resource consists of 3 pages of REDOX reactions involving the following tasks: drawing a cell diagram, balancing equations and calculating the EMF of the cell in question. The worksheet will suit students enrolled in Honors or AP chemistry. Answers are provided. Key words: AP, REDOX, Olympiad, EMF, calculations, cell diagrams.

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.

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 and 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 worksheet has bond enthalpy and lattice energy calculations and would be suitable for Honors and AP-enrolled students. Key words: Hess's law, bond enthalpy, Lattice energy, calculations.

This resource is a test that covers various aspects of periodicity: sub atomic numbers, electron configuration, assigning charge to ionic species, some electrolysis questions and a few word equations (eg. photosynthesis) requiring symbols equations. The test takes about 1 hour.

This resource contains 2 worksheets (4 pages) of crystallisation problems (and answers). The exercises would be suitable for students wanting to do Honors or AP.

This resource contains some pH worked calculations and notes. The 2-page work sheet has weak acid and weak base problems as well as 2 misconception questions are also included to encourage students to be able to explain a concept without the need of a calculator. Answers are provided. The detailed pH calculation notes are also found in the other pH calculation resources at Drog-chem’s shop.

This worksheet (and answers) contains 8 empirical formula problems. It would suit students wanting to do Honors or AP. Key words: calculations, molecular formula, empirical formula,

This test is about 1 hours long. It includes questions about calculating oxidation number, observations and balancing half and full REDOX equations. This test would be useful for students doing AP or Honors chemistry. Answers are included.

This resource has 4 related activities and a short (20-30 minute) 2 page test. There is a template microscope that can be labelled; a fun-worder on microscopes and plant cells; a handout for the students to use regarding sample sample slide preparation (2 pages) and a cross word puzzle. The 3-slide power point tries to show relative size by comparing images of viruses, sand, sugar, bacteria etc A stand-alone microscope slide template is also included should a teacher need to use different labels or use it in an exam.

This test comprises about 45 marks worth of short answer questions (4 pages long). 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. Answers are included.

This resource contains 4 simple experiments that have been successfully used in the laboratory for students aged from 10-14 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.

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 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 Honors or AP 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).
