Great science experiments for every season.
Freshwater freezes at 0°C. The presence of salt lowers the freezing point, and the higher the salt content in the water, the lower the freezing point gets. This is why salt is often used to grit icy roads in winter. It slows down water freezing on roads, making driving safer. Seawater contains salt. It will…
Find out how to dissect flowers and learn about their structure with this simple hands-on dissection activity and other exciting plant experiments for kids. Dissecting a flower is a great way to visually show the different parts of a flower, which can be hard to picture from a diagram in a book. What you need…
I’ve got some fantastic spring science experiments to share today. As always, you don’t need any special equipment, just things you either already have around the house or that you can buy easily and cheaply from a supermarket. Spring is the perfect time of year to get out in the garden and learn about the…
We gathered up the last remaining bits of snow this afternoon to make a Baking Soda Volcano using snow! A snow volcano is a great way to have some fun in the snow while learning and experimenting. I piled up a heap of snow around a small glass jar, making the top of the snow…
Winter is a great time of year to try some science at home. Ice and snow-themed experiments don’t require special materials, look great, and if you can do them outside, are almost mess free! I’ve pulled together a collection of what we think are the best winter science experiments for kids, including a free checklist…
Reindeer are animals often associated with Christmas and winter. Did you know reindeer are the only deer species where the females grow antlers? Reindeer facts for kids Reindeer are usually 4-5 feet tall! Reindeer antlers are often around 3ft long. A double-layered coat helps reindeer to stay warm. The top layer has long hollow hairs…
Robins are a bird we commonly associate with winter and Christmas, but why do robins have red breasts? The red colour looks amazing next to white snow, but it also makes the bird a target for predators. Why do robins have a red breast? There are several reasons why robins have a red breast: Male…
This simple Santa STEM challenge teaches kids about the physics of snowshoes in a fun and hands-on way. The challenge is to design a snowshoe for Santa to help him cross the snow to reach his sleigh! How do snowshoes work? Snowshoes have been used for thousands of years to allow people to walk on…
Helicopter seeds are a type of seed that spin as they fall from a tree. The spinning movement and the fact that they are light and can catch the wind allows them to travel further from the parent tree than if they just dropped to the floor. This is one method of seed dispersal used…
Over the many years I’ve been writing Science Sparks, Autumn has always been my favourite season for designing themed activities. I love the colourful leaves, dark nights, cooler weather, and, of course, the run-up to Christmas is always exciting, too! This collection of fall science experiments and activities makes me smile every time I read…
