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.
If you’ve ever made an erupting volcano model you most likely used the baking soda and vinegar reaction to make it erupt. Baking soda and vinegar react to neutralise each other ( vinegar is an acid and baking soda an alkali ) releasing carbon dioxide, which is the bubbles of gas you see. If you…
I’ve got lots of fun activities and facts about the Moon to share today. The Moon is probably more important to the Earth than you think. Did you know it stabilises the wobble of the Earth on its axis, giving us a fairly stable climate and causing tides? Moon Facts Did you know the Moon…
This heart model is a great demonstration of one chamber of the heart and valve. The heart has two features that keep blood flowing in the right direction. These are chambers and valves. Chambers fill with blood, then squeeze to pump the blood out. Each side of the heart has an entry chamber ( atrium…
What is an emulsion? Two or more liquids that don’t mix create an emulsion when one is added to the other. The properties of the new liquid are different to either of the liquids alone. Emulsions are a special type of colloid. Liquids that don’t mix together are called immiscible liquids. Examples of Immiscible Liquids…
These simple science experiments are perfect for a rainy day or when you need a quick and easy activity idea to keep the kids busy for an hour or so. They don’t need much prep or thought beforehand and are easy to set up and explain. Don’t forget I also have a couple of science…
We’re making the most of the cold weather by sticking with our ice theme this week. This ice painting science activity is super simple and great fun. I just wish I had a bigger freezer to make a larger sheet of ice. Materials for ice painting Tray ( I used the cheapest oven tray I…
Here at Science Sparks we’re trying to make the most of the festive season with lots of Santa science and ELF science challenges. Today we’ve got another Santa challenge, but you could easily make it Elf themed too! Follow our full instructions for how to build a torch and Santa will be back on his…
This blog has been paid for by and created in partnership with Pfizer UK. The #JoinTheFight campaign is sponsored by Pfizer UK. When my now 11 year old was 3 she had a terrible case of chicken pox. She had spots everywhere, even on her eyelids! She eventually recovered, but it was a long two…
Did you know you can use chromatography to separate the different colours in the coating of colourful candy? This fun science experiment is perfect for learning about separating mixtures and can even be used as a science and art activity too! This activity can also be found in my new book Snackable Science. If you…
The digestive system is made up of several organs working together to make an organ system ( digestive system ). This activity shows how to make an easy digestion system model using food and tights! This activity can also be found in my book Gross Science! What is Digestion? Digestion is the process by which…
