The electromagnetic spectrum is the name for the different forms of light that are given off by objects in the Universe. Radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays are all types of light, but with different energies! The different types of light have different wavelengths. What is wavelength? Wavelength…
The Earth is located in a planetary system we call the solar system located in one of the four spiral arms of the Milky Way galaxy. Our solar system consists of 4 inner planets ( Mercury, Venus, Earth and Mars ) and 4 giant planets (Jupiter, Saturn, Uranus and Neptune ). There are also several…
Shadows are formed when light hits an object it cannot travel through. When you see your shadow on a sunny day, your body has blocked light from the sun. Light travels in a straight line. It cannot bend around your body, so you see a shadow. Shadows change shape during the day as the sun’s…
Here at Science Sparks, we love anything space related, especially rockets! This baking soda rocket is one of our favourites, as it’s super easy to set up and can be launched over and over again! I also have a water powered bottle rocket, film canister rocket and squeezy bottle rocket you can try too! How…
All moving objects have momentum. Another way to think about momentum is how hard it is to stop a moving object. It’s harder to stop an object moving quickly than an object moving slowly. What is the momentum equation? All moving objects have momentum. Momentum is a vector quantity which means it has size AND…
Static electricity is the thing that sometimes gives you a little shock when you touch a metal door handle after walking on a carpet. It makes your hair stand on end when you put a woolly jumper on and can be used for lots of fun science experiments and demonstrations. This static electricity demonstration shows…
Have you ever had an electrostatic shock from a shopping trolley or escalator or noticed your hair standing on end when you rub a balloon on it? The shock is caused by static ( non-moving ) electricity, which is caused by electrons building up with no circuit to flow along. An object that has gained…
You may have seen our mini Archimedes screw a few months ago. It was a great STEM challenge and worked really well. Last weekend we decided to take it up a level and make a supersized Archimedes screw! Supersized Archimedes Screw An Archimedes screw consists of a hollow tube with piping twisted around it. We…
The Beaufort Scale was named after Sir Francis Beaufort ( a hydrographer with the Royal Navy ) and lists the effects of increasing wind speeds. The scale was initially designed to show the effects of the wind on a battleship at sea. When is a hurricane warning issued? Hurricane warnings are issued when winds reach…
We’ve made lolly stick chain reactions, Easter egg chain reactions and now we have a GIANT chain reaction. We actually made this a few years ago, but when I looked for the post today I couldn’t find it, so there’s no photos just this video. Simply grab a ball ( any size ) and some…
