We all know what a kilogram is – or do we? Researchers worldwide are working to define precisely what this familiar unit is.
Contrary to the popular saying, deep waters are often far from still – which is just as well for marine life. Activities using simple water tanks are a good way to find out about the physics at work beneath the waves.
Biologist Juliana Machado Ferreira is using science to combat wildlife traffickers in Brazil.
From a homemade thermometer to knitting needles that grow: here are some simple but fun experiments for primary-school pupils to investigate what happens to solids, liquids and gases when we heat them.
In the third article in this series on astronomy and the electromagnetic spectrum, learn about the exotic and powerful cosmic phenomena that astronomers investigate with X-ray and gamma-ray observatories, including the European Space Agency’s XMM-Newton and INTEGRAL missions.
Why is symmetry so central to the understanding of crystals? And why did ‘forbidden’ symmetry change the definition of crystals themselves?
Astronomers use giant radio telescopes to observe black holes and distant galaxies. Why not build your own small-scale radio telescope and observe objects closer to home?
During an eclipse, the Sun or the Moon seems to disappear. What is happening? Why not explore this fascinating phenomenon in the classroom, with an easy to build model?
For scientists at the European Space Agency, a mission to Mars means going to Antarctica first.
Something as everyday as bread can offer a surprising spectrum of interdisciplinary teaching opportunities.
