Making pH-sensitive inks from fruits and vegetables is a creative variation of the cabbage-indicator experiment.
“Before I start, I’d like to mention two things: half of what I’m telling you will be wrong; and I don’t even know which half.” This introduction by renowned molecular biologist Ueli Schibler to his students illustrates a discomforting aspect of science. The only way to find out which…
Drop by drop: Learn about pH chemistry and neutralization reactions, and produce wonderful colours using microscale methods that are cheap, quick, and easy.
Horror movies are a popular, albeit rather despised, film genre. It is all the more surprising that the most horrific of the current crop of scary movies has recently won an Oscar, not to mention the Nobel Peace Prize awarded to its main protagonist.
With oil reserves running out, silicon solar cells offer an alternative source of energy. How do they work and how can we exploit their full potential?
Great balls of fire: Try these dramatic experiments with gases to illustrate stoichiometric reactions and combustion.
Renewable, clean, unlimited energy – how can it be achieved? Christine Rüth from EFDA introduces the tokamak, the most advanced fusion device.
Karen Smith from NEF, the New Economics Foundation, London, UK, describes an approach to creating a safe space where students can discuss sensitive topics, like stem-cell research or genetically modified food. How can students be encouraged to explore their values in relation to science topics, and…
