Scientists have noted that some species of animals have dialects depending on where they live. Naked mole rats are super-social rodents. They live in colonies ruled by a queen, in a similar way to how bees live. They talk to each other with squeaks and clicks, which sound slightly different depending on which colony they are from. If a mole rat squeaks with a different sound, it might be an invader from a rival gang! DID YOU KNOW? About 25% of a naked mole rat’s muscles are in its jaws. They can chew through concrete!…

Why do I yawn? We all yawn, but nobody is sure about the reason why. We yawn when we wake up, when we’re bored or anxious and especially when we’re – yaaaaaaawn – tired! Some scientists think we yawn because we need more air or our lungs need a stretch. Others think yawns cool us down and make us more alert. Whatever the reason, we do know this: once somebody else yawns, most people can’t help yawning along with them! WACKY FACT Animals yawn, too. And dogs often join in if they see their owners yawn! Why do giraffes have long necks? A giraffe’s long neck allows it to reach leaves in tall trees that shorter creatures can’t get to. This means giraffes don’t have to compete with other animals…

An ice cream Please make sure you use rounded safety scissors. You will need an A5-sized piece of paper. 1 Trace around the outside of your scissors with a brown pencil. Make sure your scissors are not open for this shape. 2 When you remove your scissors you will have the shape of an ice-cream cone. Pick some pencil colours that resemble your favourite flavours of ice cream or your favourite colours. 3 Now draw your ice cream scoops. Start with a full circle at the front, following the numbered order. 4 Position the tip of your scissors between two scoops and trace around it, stopping before the hinge. 5 Give your cone some detail by adding cross-hatching, which are lines that show dimension. Curving the lines slightly will make…

Spring is the time of year when nature comes back to life. The sun shines brighter, the days grow longer, animals wake from hibernation and flowers start to bloom. Did you know that it is only thanks to plants that we call this season spring at all? Before the 15th century, people referred to this time of the year as ‘springing time’ or ‘the spring of the year’ because it was when plants literally sprung out of the ground. ‘Springing time’ was shortened first to springtime and then, during the 16th century, to spring. So to celebrate the return of ‘springing time’, let’s explore some of the fascinating and extraordinary ways in which flowers and other plants grow. DID YOU KNOW? Bees can fly at around 25 km/h and beat…

Skye Café Wall Illusion When you look at this image, does it seem as if the orange stripes are slanted? If you focus on just one of the stripes you might be able to see that… they’re actually completely parallel! This illusion happens because the contrasts of the light and dark colours and the angles of the black and white chequered diamonds at the intersections between the colours trick your brain. This optical illusion is called the Skye Café Wall Illusion. It was dreamt up by an illusion artist called Victoria Skye. Skye was inspired to create the illusion after seeing the tiled wall of a café, pictured left, in the city of Bristol, UK. As you can see, the green wall tiles appear to slant at different angles. Skye…

ALL THE LANDLOCKED COUNTRIES IN THE WORLD When a country does not have direct access to an ocean, or to a sea that is not landlocked, such as the Mediterranean, we say that it is landlocked. Around 20% of all the world’s countries are landlocked. On the right, you can find out some of the problems this can create and why having access to the ocean is so important. Below left, we look at the only two countries on Earth that are double landlocked. DID YOU KNOW? There are 195 officially recognised countries in the world, 44 of which are landlocked.
