Great science experiments for every season.
The summer solstice is the longest day of the year when the Earth’s North Pole is tilted closest to the sun. There are two solstices each year. One in June and one in December. The time of the solstice is the same all over the planet, but the season depends on where on Earth you…
These simple ice decorations are very easy to make, look fantastic, and provide lots of learning opportunities as children observe water freezing, becoming ice, and then melting back into a liquid. Young children will enjoy feeling the ice ( let it melt a little first ) and trying to melt it by dropping warm water…
These summer STEM Challenges are great fun, no matter the weather, and they all use materials you’ve probably already got around the house. Make treasure maps, play dough models, fizzy potions, sugar cube towers, and find rainbows in bubbles. Gather together friends or family and start experimenting. We’ve got enough ideas to keep you busy…
Can you believe it’s been over 50 years since humans landed on the moon for the first time? This historic event was not only an incredible feat of science and engineering but also led to many innovations that have improved human life since. If you have children who are fascinated by space travel ( or…
At Science Sparks, we love autumn with its crunchy leaves, beautiful colours, and crisp, fresh air! I’ve compiled a huge collection of autumn science experiments that you might like, and I’ve also pulled together these autumn STEM challenges to help you make the most of the changing seasons. If you’re looking for more general science experiments, try my collection…
Do you know how to make a solar oven? I’ve always wanted to try one, so when the UK was unusually hot last summer we gave it a go. It was actually much easier than I expected and our marshmallows melted very quickly. If you fancy setting up a few garden activities on a sunny…
Homemade Water Walls are a great summer activity. We usually make one at the start of summer and leave it in place for as long as it survives. You can be creative and use a trellis, a fence, or anything else you can wrap tubing around. Add buckets and funnels for a summer of watery…
We’ve dissected flowers many times before, but this was our first attempt at a 3D flower model. A model is a great hands-on way to learn about the structure and function of plant organs and the importance of pollination. I’ve also made some FREE flower structure revision cards you might like. 3D Flowering Plant Model…
Do you know how salt melts snow? Grit is often sprayed on roads to stop cars from skidding on very cold days. What we call grit is a mixture of salt, gravel and stone. When snow falls on a road with grit applied, it mixes with the salt, lowering the snow’s freezing point and stopping…
Have you ever wondered why penguins don’t freeze to death? Penguins have to cope with an immensely harsh environment with extremely cold temperatures and added wind chill. Animals that live in cold regions tend to have several adaptations that help them stay warm. Penguins living in cold climates stay warm thanks to their thick feathers…
