Storms are a kind of bad weather, usually made up of strong winds and rain or hail. They can cause lots of damage by blowing bits off buildings and trees, causing water to overflow from rivers and streams, or making huge sea-waves that crash onto the land.
Storms happen every year and are a normal part of the weather here on Earth. But some storms are stronger than others; the stronger the storm, the more damage it could cause. So, scientists have come up with a way to keep track of them – let’s find out how they do it…
Blood is a red, oozy fluid that is found inside our bodies. It’s an important part of our bodies and we wouldn’t be able to stay alive without it. Every part of your body needs blood, from your brain all the way to your toes, and your body has to keep it ‘fresh’ so it makes new blood every single day.
My seven-year-old wants to know why blood is so important to our bodies – what is it for? So, let’s find out about what blood is made of and what jobs it does inside us:
What makes you you and what makes me me? What makes us different and what makes us the same? And why are we human beings, not cats or bees or plants or mushrooms or germs?
The answer to these questions is chemistry – a special kind of chemistry that allows life to exist on Earth…
It’s Winter time here in the UK and the temperature outside has been close to freezing for several days. We’ve had a flurry of snow, a little ice and plenty of frosty mornings. Sometimes, the water in the bird bath is frozen, so I melt it with warm water from the tap and leave out some bread and fruit for the birds to eat if they visit our garden.
My 7-year-old has noticed the birds plumping themselves up as they sit in the bushes and hop around the bird-table. “Why do they make themselves look fat?” she wondered. Let’s find out…!
Have you ever noticed, when it’s a rainy day that lots of worms come out to play? My girls have and they like to rescue the worms that get stuck in puddles, moving them to safety in grass verges by the sides of the road. Seeing the worms wriggling about, they often ask questions about how worms live. So let’s find out more about these weird and wonderful creatures…
The weather has turned colder here and we have started giving the children hot water bottles to keep them warm in bed at night. For my 3-year-old, this is a new thing – she was pleased to have a snuggly warm toy to cuddle up to all through the night. But the next morning, when she woke up, she cried because her hot water bottle had gone cold!
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.
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?
