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.
We’ve done this light refraction experiment many times before, but this time it’s Alice in Wonderland themed. A reversing arrows science investigation is very easy and can be made as simple or creative as you wish. If you don’t want to theme it like I have below, just draw arrows on a small piece of…
I’ve got another easy EGG themed STEM Challenge for you today! It’s a bit of a twist on the traditional egg drop experiment. The challenge is to build a car using K’Nex or another construction toy to save an egg passenger. This is a brilliant egg experiment, that’s great for any time of year, but especially Easter!…
This fun tooth decay experiment with egg shells is all about teeth and how to keep them healthy. First, we discussed the importance of brushing teeth every day, and then we chatted about foods that are good for your teeth and those that aren’t. Sugary, sticky foods are not good for teeth as they stick…
One of the easiest ( and tastiest ) ways to introduce science at home is in the kitchen. If you’re a regular reader, you’ve probably already seen my huge kitchen science experiment round-up post, full of simple, tasty, and educational ideas for science in the kitchen. Pancakes are a great way to learn about how…
Fresh eggs sink, and older eggs float. Eggs have air cell that becomes bigger as they age. Once the air pocket is big enough to make the egg less dense than water, the egg floats!! Another way to make an egg float is to increase the density of the water the egg is in! Once…
Eggs with no shells are definitely one of the things my children find most intriguing. I’ve made bouncy eggs for nursery children to look at and for secondary school children to use as part of an osmosis experiment. This fun bouncy egg experiment is great fun for kids of all ages and fascinating for adults…
This collection of Humpty Dumpty science experiments is perfect for Early Years Science to fit in with a Nursery Rhyme theme. Older children could use it for practising designing an experiment following correct scientific procedures. I’ve used plastic sealable bags to keep the mess contained, but children could also wrap the egg in protective materials…
Alice’s Adventures in Wonderland is one of my favourite books, so I’m very excited about a new mini series of Alice themed science experiments and activities. My first activity is super simple. All you need is a pen, paper and a mirror! Alice encounters many strange things in Wonderland, including reversed time and a backwards…
There are three main types of rocks: sedimentary, metamorphic and igneous. Each are formed in a different ways. Sedimentary rocks contain rounded grains in layers. Chalk, shale and limestone are examples of sedimentary rocks. This activity is a very simple demonstration of how how sedimentary rocks are formed. Sedimentary rocks are formed when layers of…
Vaccines are a way to prevent disease. Vaccines introduce an inactive or altered form of a pathogen into the body. The altered pathogen contains the same antigen ( protein on the surface ) as the real disease causing agent. White blood cells produce antibodies specific to the antigen in the vaccine. If a vaccinated person…
