Giving an Effective Presentation
How to make a lasting impression when giving a presentation, for instance when attempting to complete the EXCEPTIONAL End of Topic Task about any aspect fo the topic you thought was particularly interesting, click here.
To find out what kinds of things will make a good presentation better (this is a marking scheme that is based on the IB Theory of Knowledge course, but simplified for use with iGCSE classes), click here.

Learning about sciencey by reading newspapers, journals, and popular science magazines. Not all of these magazines can be accessed everywhere, but it is important that you understand and read as widely as you can, especially about the subject you are interested in pursuing at A levels and beyond. You may need to buy a subscription, but the school library also has an excellent selection of current magazines and newspapers.
To give you a sample of the kinds of articles and things you could be reading I’ve downloaded selected articles that relate to this topic, which is about experiments. If you find the language challenging, which is likely, instead of reading for meaning you could instead try reading for vocabulary, print out an article and translate any words you may find. One way to learn another language if you are already very confident in that language is to explain the meaning of new words in English, rather than simply translate them.
The Economist (for the Science section, click here), possibly the most-read newspaper by CEOs and corporate executives, as well as politicians and academics, interviewed a famous astronomer about how science can save the world, listen to the podcast
Some of the most popular online (and sometimes offline) sources for news aimed at an educated general audience include
National Institute of Health: https://kids.niehs.nih.gov/
And especially Wikipedia, which also has a Simple English version: https://simple.wikipedia.org/wiki/Main_Page
This is where new science and discoveries is reported to the scientific community, and then the world. They follow a very specific set of rules and try to explain exactly what they did in their experiments and what they think their results mean. Normally, even after finishing a degree, it is difficult to understand what is going on in these articles (usually you just the read the abstract, which tells you roughly what they found out, and sometimes the conclusions, which tells you in more detail why their study matters) The two most famous journals are: “Nature” and “Science”.
You are unlikely to understand anything about these, but two famous experiments are included if you go to the iGCSE Additional Resources webpage.
Topic 3 Atoms, elements and compounds
Topic 3 an online simulation investigating the properties of various molecules, as well as introducing some of the features of MS Word, using the excellent BioModal website, which can be accessed here.
Topic 7.1 and 7.2 Chemical Reactions and Rates of Reaction - Exceptional Information

For a wide variety of articles that go well beyond the syllabus but should be accessible and could be of interest click here
Biology Extension Material
For students interested in reading more about biology, here's an article explaining Darwin's book On the Origin of Species, which helped to create the subject in its modern sense. And here's the original paper published by Darwin and Wallace. Other useful books worth reading include The Double Helix, by James Watson, and The Selfish Gene, by Richard Dawkins.
