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.

Electricity: interpreting circuits, calculations and some harder structured questions

Electricity: interpreting circuits, calculations and some harder structured questions

(0)
This resource consists of two 4-page worksheets (and answers). The first w/s asks the student to interpret some series or parallel circuit diagrams and calculate either I, V, R or P. The second starts with some simple calculations but finishes with short-answer questions in which the student needs to reason (rather than reach for the calculator) an answer. It encourages students to write WHY rather than just supply a simple number. If the buyer finds any mistakes please tell me and I will update the resources and send an updated version.

Biology: Scientific English for Chinese Students - Ecology

Biology: Scientific English for Chinese Students - Ecology

(0)
This resource consists of * 2 worksheets with 3 pages of science terms we use to discuss and describe aspects of ecology. The student is asked to either fill in the correct English word or Chinese word when the opposite word is given. * A crossword (and answers) that uses some of the English words in the above worksheets * A worksheet in English with missing words that the student must fill in (answers are provided). My students tell me they enjoy using these resources because they can use them as references afterwards rather than gluing in their book and forgetting about them. The students also enjoy drawing pictures to help them learn these words. If you find any mistakes please contact me. The Chinese words have been checked by a native speaker though he is does not have a science background.

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: Ice cream topic -designing, making and tasting ice cream (12-15 year old)

(0)
This is the perfect topic to end the year on. It is fun and the students don't even realise there is a serious aspect to it: healthy eating, analysing food etc. You can adjust the depth and type of learning outcomes depending on the age group (eg. if it is an older group I always include a section on microbiology and we swab surfaces and check for cleanliness, learn about how factories manage food safety etc). This topic encourages student-led learning and there is considerable enthusiasm in the classroom. You do not need to have an ice cream machine, although I did and there is often someone in the class who does have one). I have written up a rough guide on how the 1-2 weeks would go but I found that the students really enjoyed their own research and in some years this took longer than I originally had planned for. This resource includes: notes for teacher, a base ice cream recipe, ice cream in a bag activity, taste testing template, energy calculation activity and some other ideas (eg poster design). It is a lot of fun and will save you that painful end of year "now what do we do"?
Science: Tongan - The English words used in Astronomy lessons

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.
