We have had lots of fun blowing up a balloon with lemon juice today, although it’s taken several attempts to perfect our technique. This is a brilliant chemistry experiment for learning about chemical reactions! Inflate a Balloon with Lemon Juice What you’ll need A small bottle or jarLemon juiceVinegarBicarbonate of sodaBalloons Instructions Stretch the balloon…
These magnet powered cars are very easy to make and great for some competitive fun this Easter. My 10 year old and I had a brilliant time trying to build a car big enough to hold an egg safely, but small enough to move easily. It’s a bit of a fine balance! You’ll need K’nex/LEGO…
When you think of great science experiments for kids one of the first that springs to mind is probably a baking soda volcano and vinegar volcano. I remember making one with my little brother in the kitchen when he was about 4 or 5. Baking soda volcanoes and coke floats were our favourite summer activities….
This Candy DNA model is a great way learn about the structure of DNA. Did you know that 99.9% of the DNA of each person is the same? It’s just that tiny 0.1% that makes us all different! Isn’t that amazing? Humans also share 60% of their DNA with fruit flies which is even more incredible!…
With only 8 days to go until British Science Week, we’ve been busy planning lots of extra special activities for the 10 day celebration of science, technology, engineering and maths. Are you joining in this year? If you haven’t made any plans yet, it’s not too late. There are some brilliant science activity packs based around…
Here at Science Sparks, we love science tricks and super simple science experiments. This disappearing coin trick is both! The trick uses refraction of light to make it look like a coin under a glass disappears! Impress your family and friends with this simple science magic trick and learn about light at the same time!…
Did you ever make homemade scratch-art paper pictures as a child? I remember making them using coloured pencils with black crayon over the top. They took an age to make and never worked that well. If only I’d known then that oil pastels make it so much easier!! If you don’t have oil pastels, crayons are…
Have you heard about Terrific Scientific from the BBC? BBC Terrific Scientific is a fantastic primary science campaign aimed at encouraging children to think differently about what it’s like to be a real scientist. Here at Science Sparks, we’re all about making science fun and accessible to everyone, so we think BBC Terrific Scientific is…
We know from our play dough circuits that the circuit needs to be complete for electricity to flow, but we usually want to be able to control whether electricity flows or not. This can be done using a simple switch. How to make a simple switch The basic circuit below has a switch made using…
We’ve been doing a lot of space themed activities recently focussing on the many famous scientists who changed people’s perception of the Universe. In the 1600s many people thought that the Earth was at the centre of the Universe, until Copernicus used mathematical models to prove that the Earth actually orbits the Sun. We’ve used…
