Science Sparks is full of easy and fun science experiments for kids to do at home. Our fun science investigations include engineering, coding, biology, chemistry and physics experiments.
Learn more about the wonderful world of science by trying our exciting science experiments, cool facts, free printables, photos and videos. We’ve also got a great collection of STEM projects, STEM Challenges and science fair projects.
Our science experiments include removing the shell from an egg, launching bottle rockets, create edible life cycles, making lava lamps and lots more science experiments for kids of all ages.
Did you know that the Earth is about 3 million miles closer to the sun in winter than in summer? This year (2026), Earth is closest to the Sun on Saturday, 3rd January. This specific point in the Earth’s orbit is called perihelion. The point in Earth’s orbit at which the Sun is farthest from…
These light up paper circuit cards were much easier to make than I expected and only need a few inexpensive materials. They’re a great way to learn about circuits and electricity. You can make a simple, basic circuit or a more complicated series or parallel circuit. I’ve created a free template to make the activity…
These walking reindeer made us laugh so much. They work brilliantly, but can be a little fiddly to get going. This activity is traditionally called the walking horse, but as it’s nearly Christmas, we’ve made reindeer! The reindeer *walk* down a ramp or slope, because of a combination of forces including gravity and friction. You’ll…
This fun elf-themed basketball STEM challenge is a great hands-on science activity for learning about transfer of energy. The idea is to build a lolly stick catapult and a basketball net for an elf! You could set this up as a ready made activity and encourage children to experiment using different projectiles on the catapult….
Keep the kids busy over Thanksgiving with these easy STEM Challenges. Science activities and challenges are a great way for kids to learn without realising. I’ve made these challenges simple, inexpensive and great fun to do with family and friends! Learn about strong shapes with a turkey tower, find out why calcium is so important…
Have you ever seen a jumping bean toy? They bounce, flip and jump as if they’re magic, but the real magic is that you can make your own jumping bean with just a marble and kitchen foil! You might be wondering how a foil and a marble can flip and jump. The answer is physics!…
If you’ve spent any time with kids recently, you’ve probably heard the slang term “six – seven“. It seems to have no meaning, just a general playful, in with the joke type phrase. Six – Seven is often accompanied by a palm up, hands moving up and down action. The slang term 6-7 is fairly…
This simple apple ramp STEM challenge is a brilliant, hands-on way to learn about the effect of gradient on speed and friction. We’ve made a friction ramp to test toy cars before, and this apple version is a fun twist for an autumn themed STEM activity. The ramp is covered with bubble wrap to increase…
Have you ever wondered how fireworks fly? The science behind the flight of a firework is the same as that of a rocket, and a fantastic demonstration of Newton’s Third Law of Motion. For every action there is an equal and opposite reaction. Just like a rocket, a firework needs a force to overcome gravity….
I’m excited to share a fantastic guest post from the online learning platform Brighterly today. Brighterly has hundreds of expert tutors and is great for helping kids aged 6 to 15 improve their maths and reading skills in a fun, hands-on way. For many kids, math can feel complicated and overwhelming, all numbers and zero…
