I am a Science and Chemistry teacher focused on Cambridge IGCSE and AS/A. I am also heavily involved in the National Chemistry Olympiad program. By way of background I have a PhD in inorganic chemistry and entered teaching after 13 years in the food industry. I guess I am a bit old fashioned - I don't use twitter and I have no idea what instagram or Pinterest are......but I love my subject and I love working with students.

Chemistry: organic - elucidation of unknowns for AS or IB students

(0)
This resource consists of two worksheets. The first work sheet is based on a series of unknowns (a-o) that are either a reagent or a product (about 30-50 min. to complete depending on ability of student). The reactions are limited to oxidation, reduction, nucleophilic substitution, chlorination, cyanation and addition reactions. The worksheet will suit students A-level chemistry or with an interest in the National Chemistry Olympiad competition. The second worksheet (ws3) is 3 pages long and has 24 questions requiring either structures, short answers or descriptions for answers. Answers are included.

Biology: ecology - matching kingdoms and definitions

(0)
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.

Chemistry: weak acid-base and difficult buffer calcs-1

(0)
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.

Chemistry: lewis structure and molecular shapes-ws3

(0)
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.

Chinese - Geology

(0)
This bundle of resources contains material that will help a native Chinese student manage the new language and subject material that will likely appear in a geology lesson. It includes word lists in Chinese and English that need to accompanying word in the other language, cloze activities, a test and a diagram to label.
Tongan-English Science words used in physics and practical laboratory lessons

Tongan-English Science words used in physics and practical laboratory lessons

(0)
This resource contains key words that Tongan students will need to learn if they are to manage science lessons in physics and laboratory practical sessions. TESOL teachers will note that direct word for word translations are not easy and often multiple words are needed to explain a concept. I have used a Tongan teacher to help me with the translations. A key strategy I use is to ask the students to draw diagrams to help them explain what they mean.
Science: Tongan - The English words used in Astronomy lessons
DrogchemDrogchem

Science: Tongan - The English words used in Astronomy lessons

(0)
This resource consists of the list of key words used in Astronomy lessons (15-17 years old). Tongan students often come to Australia or New Zealand for further education but do not have support outside the TESOL class in terms of key Science words. Would you believe there is no word for spring tide? It requires a lengthy description. It is examples like this one which help illustrate why Tongan students often struggle in the English dominated classroom. Some cloze-style problems and a word finder are also included. Topics include tides, seasons and phases of the moon. This resource would help NZ students who are studying the Internal assessment AS 90954.

Chemistry: practical - careful choice of an Indicator

Chemistry: practical - careful choice of an Indicator

(0)
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.

Chemistry calculations: using the formula n = m/M and calculating % composition

(0)
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.
