Year 6 Science Week Work!

This year’s British Science Week had the theme of ‘Journeys’, and Year thought about the journeys made within us!

According to the British Science Week website: ‘Our brains control everything we think, feel, say and do. Inside our brains we have around 80 billion cells called neurons. Luckily, neurons are tiny, so we can fit them all in — about 30,000 neurons could fit on a pinhead!

A neuron connects to lots of other neurons; every second, millions of electrical signals journey through your brain, passing from neuron to neuron, a bit like a tiny game of
pass the parcel.

When you learn something new, neurons make new connections. When you remember something, a signal passes through these connections.

Year 6 used pipe-cleaners to create their own versions of a neuron, based around the central cell body, with small branches that come out of the cell body and receive signals, called dendrites.

They added long tails on their cells called the axon, and this carries electrical signals to the end of the cell.

Finally, they added more dendrites to the axon. These are the branches that pass connections onto the next neuron.
