This simple science project shows you how to make a model of an eclipse to visually demonstrate what’s happening between the Sun, Earth and Moon during a solar or lunar eclipse. A solar eclipse model is a fantastic science project for home and school, especially just before or after an eclipse! You’ve probably noticed shadows on Earth. Shadows form when the sun shines on an object, but did you know planetary bodies also cast shadows in space? What’s the difference between a solar eclipse and a lunar eclipse? A lunar eclipse happens when the Moon passes into the Earth’s shadow. The Earth’s shad ..read more

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 the same size in the sky. Solar Eclipse Resources and Activities Find out how to view an eclipse safely with AAS. Earthsky also has some great tips and advice for protecting your eyes during an eclipse. Frugal Fun for Boys has a brilliant DIY Pinhole Projector for viewing a solar eclipse. Learn about the phases of the moo ..read more

Blow Up a Balloon with Warm Air Science Experiment

by Emma Vanstone
1M ago
This simple science experiment and demonstration is a great way to show children what happens to gases when they are heated. The air around us is an example of a gas. Particles in a gas can move freely in any direction. Gases don’t have a fixed shape but fill the space they have. When a bottle with a balloon on top is placed in hot water, the air inside warms up. Warm air particles move faster and with more energy than cooler air particles, increasing the volume of the air and inflating the balloon. Hot and cold air balloon experiment You’ll need One empty 500ml plastic bottle A balloon Two bo ..read more

Pi is the ratio between a circle’s circumference and diameter. It’s a number used in many formulas associated with circles. The circumference is the distance around the edge of a circle Pi to two decimal places is 3.14. The symbol for Pi was first introduced by a Welsh mathematician called William Jones in 1706. Pi Day is March the 14th, as 3.14 are the first 3 digits of pi. Pi Day was first celebrated at San Francisco’s Exploratorium Museum. Archimedes is thought to be the first person to have calculated the value of pi accurately. Pi is an irrational number which means it goes on forever wi ..read more

Why do we hiccup?
Science Sparks | Kids Science Blog
by Emma Vanstone

Hiccups occur when the diaphragm starts to spasm. No one really knows why they happen, but they’re thought to happen when the diaphragm gets irritated or stimulated. The diaphragm is a thin layer of muscle that separates the chest cavity from the abdomen. When it spasms and tightens, it makes you breathe in air too quickly. The air is stopped when the glottis ( opening between the vocal cords ) closes suddenly, which is what makes the hiccup sound. Hiccups are usually temporary and more annoying than anything else, but persistent hiccups should be investigated by a medical professional. Causes ..read more

Do you like to dunk a biscuit in a hot drink or a glass of milk? Do you find some biscuits are better for dunking than others? Personally, I’m a big fan of the chocolate digestive to dunk. The combination of melted chocolate and soft biscuit is the best! What makes a good dunking biscuit? Do you like to dunk a biscuit more than once, or do you prefer one dunk to give the perfect melty texture? We designed an investigation to find out which type of biscuit is best to dunk. Everyone can probably agree that a biscuit breaking and landing in the drink is never a good thing, so we placed six differ ..read more

What are ultra-processed foods?
Science Sparks | Kids Science Blog
by Emma Vanstone
1M ago
Ultra-processed foods are food products that are heavily processed before reaching supermarket shelves. These types of foods usually contain lots of chemicals such as preservatives, sweeteners, food colouring and emulsifiers. Generally, the more a product has been altered from its original form, the more likely it is to be ultra-processed Ultra-processed foods are usually of low nutritional quality with high levels of sugar and salt. The benefit of ultra processed foods is that they typically taste good and have a long shelf life, but if eaten in excess can contribute to health issues. It’s t ..read more
