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.
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. Collective nouns aren’t always the terms used by scientists, who tend to stick to more…
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…
The 2026 Football World Cup might be coming to an end, but football is ever popular in my house, so here are Four Football World Cup STEM Challenges for you to try this summer. All the activities use very basic materials, and I’ve included free printable templates for the reaction time test and goalkeeper game….
Ultraviolet (UV ) light is invisible radiation that can damage your skin and eyes if you don’t protect yourself. If your kids are anything like mine, they find sunscreen a bit of a sticky inconvenience, so UV beads are a fantastic way to visually demonstrate how sun cream protects our skin from too much UV…
When you’re feeling warm and sticky, a hot drink probably isn’t top of your list, but it can actually cool you down faster than a cold one under the right conditions. How does a hot drink cool you down? If you’re already feeling warm and your body detects additional heat from a hot drink, it…
If you’re feeling the heat this week, a DIY sprinkler is a fun way to cool down. All you need is a plastic bottle and some water. This fun backyard science activity is a fantastic demonstration of gravity and air pressure. How can tightening the lid of a bottle stop water from flowing out of…
Do you know that adding carbon dioxide to water makes it more acidic? We used red cabbage indicator to test the pH of tap water and carbonated water from a Sodastream. The tap water was slightly alkaline, and the fizzy water was acidic! This is another great way to demonstrate the effect of carbon dioxide…
Submerging a dandelion in water always looks impressive, as the delicate puffball (seed head) appears wet in the water but is completely dry when removed. It’s a bit like a super high-tech rain coat. Several factors contribute to the waterproof properties of a dandelion seed head. This investigation uses dish soap ( washing up liquid…
Can you save an egg astronaut from a sticky end? Test different materials to find out which protects an egg the best from a rocket launch and a crash to the ground! We used a mini baking soda and vinegar powered rocket, but you could also try this activity with a water powered bottle rocket…
If you’re looking for easy creative ideas to keep the kids busy over Easter, you’re in the right place. These Easter STEM projects are simple, use equipment you probably already have, and most importantly, are great fun! Raid your recycle bin and get ready for hours of science fun! Easter Egg Chain Reaction Last year,…
