Have you ever wondered why fizzy drinks make you burp? Read on to find out and try a science activity to demonstrate! Fizzy drinks are fizzy because they have carbon dioxide gas pumped into them under high pressure. If you have a SodaStream at home, you’ve probably seen how adding the gas makes water fizzy….
A shooting star isn’t really a star, it’s usually a small piece of rock or dust burning up as it hits the Earth’s atmosphere at high speed. As the rock moves through the atmosphere it heats up and glows. Is a Shooting Star a Meteor? Yes, astronomers call shooting stars meteors. They mostly burn up…
Have you ever been outside on a warm day after it rained and wondered what the lovely, earthy smell is?

You’ve probably never sat down and thought about what soil is actually made of, but it’s a lot more than just mud and dirt. It plays a crucial role in supporting life on Earth, anchoring plant roots, delivering vital nutrients, and providing a habitat for billions of microorganisms alongside creatures like earthworms, ants, and beetles….
Are you ready for the solar eclipse on the 12th August? The last eclipse in the UK like this was back in 1999 and really doesn’t feel like it was 27 years ago! This Wednesday, a total solar eclipse will be visible over Greenland, Iceland, Spain and parts of northern Portugal. The UK and Ireland…
A solar eclipse is when the Moon passes between the Sun and Earth, blocking the Sun’s light. People on Earth who are in the path of the Moon’s shadow will be able to see the eclipse. The Sun is 400 times wider than the Moon and 400 times farther away, which is why they appear…
You probably already know that a group of wolves is a pack, cows form a herd, and birds fly in a flock, but beyond the expected, there are some hilarious, unexpected, and incredibly apt collective nouns for groups of animals.

A heatwave is defined as an area being unusually hot for 3 or more consecutive days, but what causes hot weather? Hot weather is caused by high pressure. When an area of high pressure pushes down on the ground, the air compresses and becomes hotter and drier. The high-pressure system pushes clouds out of the…
