Easy science experiments for winter. Featuring ice experiments, snow experiments and more.
The 2026 Winter Olympics start tomorrow, bringing athletes from around the world together to compete for a coveted gold medal! Here at Science Sparks, we’re looking forward to watching gravity-defying spins, jumps and twists and super speedy slides. Winter Olympic sports are full of cool science, the games are a bit like a huge, frozen…
It’s freezing cold outside today, so we’ve been trying some indoor winter science activities. These crayon resist snowflake pictures have been a big hit, and they are very easy to create. Younger children love to watch the images appear as they paint over them, but this activity is also a fun way for older children…
Did you know that no two snowflakes are the same? Snowflakes all take slightly different paths to the ground as they form, which is why each one is unique. How do snowflakes form? Snowflakes start with a tiny speck of pollen or dust floating in a cloud that acts as a seed. When a very…
A tower of slippery ice cubes might sound impossible to build, but adding a little salt makes it much easier! Materials Ice – 4-8 cubes Salt Plate or tray Instructions Try to stack the ice cubes. They will topple off each other. Leave the ice cubes to melt for a few minutes. Try to stack…
A family ski holiday is a great time to try some snowy science experiments, especially if you live somewhere where there’s not usually much snow. An alpine ski resort is the perfect location for lots of exciting science. From appreciating the effects of altitude on the human body and the impact of a frozen landscape…
Snowy days are great for exploring the wonders of science right outside your front door. Older kids will enjoy making a snow volcano or designing snowshoes, while younger kids love searching for animal footprints or building mini snow sculptures. If you don’t want to spend too long outside, grab a tray and bring some snow…
Next on our trip Around the World in 50 Experiments is Lapland! Lapland is a huge region in northern Finland. It extends from the Arctic Circle to the borders of Norway and Sweden. The original people of Lapland are the Sami people. Many still live a traditional lifestyle. Lapland has a varied landscape, including forests,…
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…
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…
