If you’re immune to a particular virus or bacteria it means you already have the right antibodies in your blood ready to fight the pathogen when it enters your body. What is Natural Immunity? There are two ways a person can be naturally immune to a pathogen. When antibodies are passed from a mother to…
The Earth is known as a Goldilocks Planet, as, rather like the littlest bear’s porridge, it is neither too hot nor too cold. It is this favourable temperature which allows life to exist. Earth is the only planet we know of where water can be in the form of a gas, liquid or solid ( remember…
We’ve yet to see any real snow this year, despite promises of downfalls in November, so we decided to make some fake snow of our own. We made three different types of pretend snow and set about exploring their different properties for a wonderful snowy sensory experience. Don’t forget to try my other winter science…
I originally created these science experiments for parents at home with children during lockdown 2020, but they work well as science activities for home or school at any time of year. The idea behind Tray a Day is that everything you need for the activity fits in a tray, so it’s easy to set up…
We made these virus models to show how different viruses have very different structures. They are also different sizes ( our models are not to scale ) and infect different types of hosts. At a very basic level each virus consists of genetic information in the form of either DNA or RNA surrounded by a…
A virus is a very tiny organism that can only live and reproduce inside another living cell. The cell the virus invades is called the host cell. The virus basically turns the cell into a factory to make more viruses which then invade more cells. Viruses consist of a stand of genetic information ( DNA…
A leap year has 366 days instead of the usual 365 days. We refer to a year as being a leap year when February has an extra day. February 29th is often called a leap day. Why do we have leap years? It’s all to do with the Julian or Gregorian calendar ( which has…
If you’re searching for child-friendly science experiments, look no further! Most of the science experiments on Science Sparks are perfect for science at home. I try to use materials that are either easy to find or that you probably already have around the house. All my science investigations and activities are simple, easy to explain,…
I loved making these gingerbread houses, originally they were going to be a craft project, but then I had the idea of using coloured cellophane for windows and using them to learn about primary and secondary colours. You can keep it really simple and just use a torch to light the inside or if you…
As we head into a cold January, I thought it might be fun to try some fun winter science experiments for kids. These are great for kids of all ages, although some need adult supervision and guidance. If winter isn’t quite what you’re looking for, I’ve got 100s more creative science experiments for kids to…
