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.
Hot air balloons work thanks to convection currents. The heat source under the balloon heats the air inside. A convection current inside the balloon keeps the air warm as heated air continually rises, cools and falls to be heated again. The warm air inside the balloon is less dense than the cooler air on the…
This super simple STEM challenge requires only a straw, a potato and a willing volunteer. You’ll need Two paper straws A large potato ( raw ) Instructions Pick up one of the straws and try to push it into the potato hard. The straw will most likely bend. Take the second straw, and this time…
This activity is a fun introduction to chromatography while learning about the different planets in our solar system. The idea is that children create each planet using filter paper while thinking about the size and colour of each one. It’s impossible to get the size comparisons right as the difference, in reality, is so vast,…
Summer is a great time to get outdoors, play, explore and learn at the same time. I often find that if I set up some outdoor science experiments, my children keep coming back to them over a period of weeks or days, each adding their own twist to the activity. What makes a great outdoor…
Rockets make a great science project or space-themed STEM Challenge as they are fairly easy to make, can be personalised however you want and reused over and over again. These easy rockets kids can make are also fun craft projects and can be turned into a science investigation! My personal favourite rocket is our mini…
Ammonites were sea creatures that lived before and at the same time as dinosaurs. They were a bit like a modern-day squid or octopus with a shell. Ammonite fossils have been found all over the world. The fossils resemble a curled-up snake, and for a while, people thought they were remains of snakes, earning them…
Atoms are tiny particles of matter which make up everything in the universe. Everything you see is made up of atoms. Scientists spent many years trying to understand the structure of the atom, with several models and theories being disproved or improved upon along the way. Today we know that atoms consist of a nucleus…
A smartphone is a great tool for science experiments with or without special apps. Make the most of your phone with these five science experiments you can do with a smartphone. Use your smartphone for science Make a smartphone speaker Imagine you’re in the park having a picnic and fancy playing some music. What can…
The Periodic Table is a table of all the elements we know about today. Elements are placed in order of atomic number ( number of protons in the nucleus ). The periodic table is a way of listing and organising elements. The rows of the periodic table are called periods, and the columns are known…
It’s time to head off on another adventure Around the World in 50 Experiments. Today we’re off to Israel. Israel is a small country in the Middle East on the eastern shores of the Mediterranean. Israel has a population of around 9 million people and shares a border with Egypt, Jordan, Syria and Lebanon. Its…
