Does salty water freeze? Science Investigation
Freshwater freezes at 0°C. The presence of salt lowers the freezing point, and the higher the salt content in the water, the lower the freezing point| Science Experiments for Kids
Have you ever wondered why a bag of crisps ( or potato chips ) expands on an aeroplane? It's all about air pressure. The crisp packet was sealed at a lower altitude where atmospheric pressure is higher than at higher altitudes. As a plane takes off and altitude increases, the atmospheric pressure outside the bag […] The post Why Do Crisp Packets Puff Up at High Altitude? The Science Explained appeared first on Science Experiments for Kids.| Science Experiments for Kids
Life on Earth depends on the light and heat from the Sun. While the warmth from the Sun gently warms you on a sunny day, the core of the Sun is a mind-blowing 15 million degrees Celsius ( 27 million degrees Fahrenheit), and the surface is 5500 degrees Celsius ( 10000 degrees Fahrenheit). That's hot […] The post How hot is the Sun? appeared first on Science Experiments for Kids.| Science Experiments for Kids
You've probably seen or experienced most of these common science phenomena before, but you may not have thought about why they happen. From sticking a magnet onto your fridge to colourful lights in the sky, we explain ten fascinating phenomena and offer ideas for learning more about each one. Get ready to delve into the […] The post The Science Behind 10 Everyday Phenomena appeared first on Science Experiments for Kids.| Science Experiments for Kids
Einstein Rings are a type of gravitational lensing in which the light from a galaxy or star passes a large object, like another galaxy or black hole, and is bent around it. If the alignment is right, the light appears as a ring around the large object. The galaxy or black hole closest to the […] The post What are Einstein Rings? appeared first on Science Experiments for Kids.| Science Experiments for Kids
Extreme weather is a weather event that is unexpected and significantly different from normal weather patterns. Weather around the world is naturally variable, but extreme events are becoming more common and intense. Extreme weather Examples of extreme weather What causes extreme weather? Extreme weather events have many causes, both natural and human-made. Greenhouse Gases Burning […] The post What is Extreme Weather? appeared first on Science Experiments for Kids.| Science Experiments for Kids
Have you ever wondered how a sea is different to an ocean? The two are often used interchangeably, but they have many differences. Differences between an ocean and a sea Oceans are bigger than seas. They cover 70% of the planet and have an average depth of 3800m. Oceans are not contained by land. Seas […] The post What's the difference between a sea and an ocean? appeared first on Science Experiments for Kids.| Science Experiments for Kids
The Earth rotates once on its axis every 24 hours. As it rotates, the sun shines on different parts of it. When the sun shines on one side of the Earth, it's daytime and nighttime on the opposite side. What are time zones? The Earth is divided into 24 time zones. Everyone in each zone […] The post What are Time Zones? appeared first on Science Experiments for Kids.| Science Experiments for Kids
The deepest part of the ocean is in the Challenger Deep valley of the Mariana Trench, which is about 10,935 metres deep ( almost 11km )! This is deeper than Mount Everest is tall. The Mariana Trench is in the Western Pacific Ocean. The deepest section is named after the two ships that first explored […] The post How deep is the ocean? appeared first on Science Experiments for Kids.| Science Experiments for Kids
Have you ever wondered why balls bounce? This activity uses differently shaped balls to investigate how and why balls bounce differently. I've included FREE instructions for a science investigation to find the bounciest ball with a handy table for recording results. Balls to use: Look at the differently shaped balls and try bouncing them on […] The post Why do balls bounce? appeared first on Science Experiments for Kids.| Science Experiments for Kids
Universal Time or Coordinated Universal Time ( UTC ) is the world's reference point for time. It's like a huge, extremely accurate clock for everyone, no matter where they are on Earth. Universal Time was once based on Greenwich Mean Time, which is based on the Earth's rotation, but that has changed to precise atomic […] The post What is Universal Time? appeared first on Science Experiments for Kids.| Science Experiments for Kids
