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.

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"?

Chinese-English - learning the English words for the elements of the periodic table

(0)
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.

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 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.
