These articles can be taken from anywhere: a newspaper, internet sources such as IFLS, buzzfeed, etc. The onion is NOT a reputable source for articles. These articles should talk about some chemical phenomena that you encounter in your everyday life (the article itself doesn’t have to explain how you encounter it in your daily life). You will summarize the article briefly (4-5 sentences), and explain briefly (another 4-5 sentences) how/why it affects your daily life.
*With summarization!
