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.
A variable is a factor in an experiment that can be changed. When you set up an experiment in the correct way you need to think about control, independent and dependent variables. What is an independent variable? The independent variable is the factor changed in an experiment. There is usually only one independent variable as…
Fossils are the preserved remains of animals and plants that lived a long time ago. Fossils can also be evidence of a prehistoric animal or plant, such as footprints or evidence of nests or burrows. These are called trace fossils. Not all remains become fossilised. Fossilisation is actually quite rare. Most animal and plant remains…
Single use plastics are plastic items that are designed to be used just once. Things like food packaging, straws and water bottles are all single use items. Around half the plastic thrown away is single use, although hopefully, this percentage is dropping as the use of reusable drinking bottles and straws becomes more common Did…
Choose a question to investigate with the Science Sparks Squad. Each week we’ll add a new science question and associated activity to help you find the answer! This idea is that you print off a question you’re interested in and then try the activity to find the answer! Each science experiment or investigation is designed…
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…
Alice’s Adventures in Wonderland is a great book to use for science investigation inspiration. Make fizzy potions with baking soda and vinegar, think about growing and shrinking, learn about the animals featured in the book ( the White Rabbit, Caterpillar, Cheshire Cat ), create your own backwards clock and lots more! Magical backwards writing Find…
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…
Are viruses alive is a tricky question that has caused a some debate over the years. The general view is that viruses are not alive. They don’t respire, convert nutrients into energy or excrete waste products like organisms we class as being alive do. Viruses can’t even reproduce without taking over another living cell. Once…
Generally the bigger an organism is the smaller its surface area compared to its volume. Surface area to volume ratio is a really important factor in how well an organism can exchange substances with its environment. A large mammal like a human could never absorb enough oxygen to survive through its skin which is why…
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…
