...solar system, or are they frozen ice and mud? Does Titan have a rocky core overlain directly by an icy mantle, or does it have an ocean below the surface? If so, is it made up of water? This all matters because what we have learnt about Titan from Cassini and Huygens has confirmed that it has an active chemistry, based on methane and ammonia. We know that these...

Primary science: supporting children’s learning

...solar system (big idea). Young children may play with parachutes and observe that they ‘slow down’ a falling object (small idea). Older children will learn about the gravitational and air resistance forces involved in this interaction (big idea). Children can develop ‘small ideas’ as steps towards the bigger ones. Braund and Leigh (2013) argued that in this way,...

For instance, it is becoming less profitable to be a miner, especially as the energy required increases. At some stage the cost may...
