The weather has turned colder here and we have started giving the children hot water bottles to keep them warm in bed at night.

So, why does a hot water bottle go cold overnight? Where does all the heat go?

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.

“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?
