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.
The answer is more than I had! We managed to light an LED with two lemons and could see between 2 and 3 volts from the lemon batteries on a voltmeter, but the current passing through was very small. Even with 6 lemons we couldn’t light a small screw lightbulb. Turn a lemon into a…
Art Bots or Scribble Bots are great fun and provide many investigative opportunities. This simple version uses a small motor and pens fixed around a pot. The motor makes the arm ( glue stick or cork ) spin, which in turn makes the Scribble Bot move. Pupils can be given challenges, such as finding a way for…
Making circuits is great fun for kids of all ages. If you have little ones play dough circuits are a great kid-friendly activity for learning about electricity. I’ve used these with children as young as 4 ( supervised, of course ) who have loved the creativity of the whole experience. For older children, cardboard circuits,…
How much does the Earth weigh? We obviously can’t put the Earth on a gigantic scale so it needs a tricky calculation to work it out. Scientists calculate how strong the gravitational pull on other planets is to calculate weight. Heavier planets have a stronger gravitational pull. We talk about a planets mass rather than…
Isaac Newton’s laws of motion explain the relationship between an object and the forces acting on it. The laws might seem very obvious today, but when Isaac Newton was alive, they were revolutionary and formed the basis of modern physics. Isaac Newton built on ideas from Galileo Galilei, Jean Richer and Rene Descartes. It is…
Our easy rock investigation making edible rocks is a great introduction to different types of rocks and the rock cycle. Chocolate is perfect for learning about the rock cycle as it can be heated, cooled and compressed just like real rocks. This activity uses chocolate to demonstrate how three different types of rocks form. Edible…
The infamous Skittles experiment is easy, low-cost, and provides lots of investigative opportunities. After trying with warm water, one idea is to use cold water, vinegar or fizzy drink to see if the final result is different. The Skittles experiment is definitely a must-try science investigation for kids of all ages. It never gets any…
Monaco is the world’s second smallest country, but one of the richest! Monaco is located on the French Rivera and is well known for it’s wealthy inhabitants and the annual Monaco Grand Prix! This post is part of my Around the World in 50 Experiments series so don’t forget to check out the rest! Where…
The first person in space was a Russian cosmonaut named Yuri Gagarin who completed a single orbit of the Earth on the 12th April 1961 onboard Vostock 1. Yuri’s spaceflight lasted 1 hour 48 minutes. The second person in space was Alan Shepard, Jr on May 5th 1961 aboard Mercury-Redstone 3. Less than 10 years…
Leprechauns are a much loved aspect of Irish folklore and have become a symbol of Ireland. They are usually portrayed as happy little old men dressed in green, but historically they were the trickster shoemakers of the fairy world, thought to live in hollowed out tree trunks or caves. Popular culture often shows a leprechaun…
