Our brains are amazing! The average human brain weighs about three pounds, looks like a big grey wrinkly sponge, and generates enough electricity to light a bulb, or even to charge an iPhone.  The brain controls everything from breathing and blinking to our emotions and memories, through firing electrical signals between brain cells – or neurons – across tiny gaps called synapses. We have approximately 100 billion neurons in our brain, all interconnected by synapses. Because each neuron is connected to lots of other neurons, there are approximately 1 quadrillion synapses – that’s 1,000,000,000,000,000 synapses! This is equal to about a half-billion synapses per cubic millimetre. No wonder our brains are so sophisticated!

Despite all that complexity, the video above is a really clear and simple introduction to how our brains work – and how they learn most effectively. There are all sorts of great tips in there to help us all be better learners. Have a watch and see if you can put it into practice!
