We visited Bournemouth at the end of October and my daughter and nephew found these unusual-looking shells on the beach. They brought them to show me and asked if I knew what they were.
From the top, they looked like several shells stuck together but, from underneath, they looked like a single creature. They were quite heavy and I could see something dark and squidgy inside, so I knew there were creatures living in the shells. But I had never seen anything like this before (even though I used to live near the sea)!
We put them back where we found them and I promised to find out more about them when we got home. So, what are these shells and why do they look so unusual?
Human beings have been thinking about and counting time for thousands of years. The first time-keeping machines used sand, water or the position of the Sun in the sky to mark out the passage of time. These days, we use clocks and watches for telling the time. But however we do it, our measurement of time is based on the movement of our planet Earth in relation to the Sun.
Fish are cold-blooded animals that live in water. Most fish have scales on their bodies, use gills to breathe and have fins instead of arms or legs or fingers or toes. And they range enormously in shape and size – from tiny seahorses to huge whale sharks!
But have you ever wondered if and how fish can hear? We have! So, let’s find out more about fish and how they sense the watery world around them…
“Remember, remember the fifth of November, gunpowder, treason and plot…”
Bonfire night is an annual celebration in Britain. It is celebrated on November 5th every year and marks the failure of a plan, called the Gunpowder Plot, to blow up the Houses of Parliament in London. It is tradition to mark the occasion by lighting bonfires and holding firework displays.
Fireworks were invented hundreds of years ago and are used for lots of different types of celebrations and festivals throughout the year. My daughters want to know more about how fireworks work and how do they make such bright colours in the sky?
