British Science Week 2025 is here! This annual celebration, organised by the British Science Association, brings ten days of exciting science, technology, engineering and maths (STEM) fun. From 7^th to 16^th March, we’re encouraged to take part in engaging activities and events with the goal of inspiring people of all ages to explore the wonders of STEM! From schools and community groups to parents and businesses, anyone can get involved in science themed fun and at eatsleepdoodle we can’t wait to take part!

 

Why is it important to teach kids about STEM?

STEM subjects are all around us – from nature to mechanics, they shape the way we understand and interact with the world! Whether looking back at the lives of the dinosaurs or exploring the future of space travel, science helps us ask questions and find answers about our world. Encouraging children to explore these subjects from an early age is so important in helping them develop critical thinking, problem-solving skills and a lifelong love of learning and discovery!

At eatsleepdoodle, we believe that learning should be fun! We are also huge fans of all things science and know the vital role it plays in shaping young minds. For us, it is super important to find ways to combine learning about STEM with fun activities – by making STEM exciting for kids, you can help nurture their natural curiosity and show them that science and creativity go hand in hand. Whether it's exploring the properties of water, understanding how animals adapt to their environments or experimenting with the wonders of chemistry, we love how science is full of opportunities for hands-on (sometimes messy!) learning and imaginative thinking!

 

Change and Adapt…

Each year, British Science Week introduces a new theme, and this year’s is ‘Change and Adapt.’ As the event enters its fourth decade, 2025 is the perfect time to think about how the world is evolving and how we can embrace and respond to these changes. From nature’s incredible ability to adapt to shifting environments to the way technology is transforming our daily lives, this year’s theme aims to encourage kids to explore the science of change and adaption in a fun and engaging way.

Understanding adaptation is key to so many areas of science - whether it’s how plants and animals evolve over time, how humans develop new solutions to challenges or how we can use science to respond to global issues like climate change. In the spirit of this year’s theme, we made a list of some great activities we love that help kids learn about change and adaptation:

 

Make your own animal!

Why not get creative and design your own animal with awesome adaptations! Using paper, cardboard or even items bound for the recycling, kids can craft their very own creature - whether it’s a real animal or a totally made-up monster! Will it have thick fur to survive in the Arctic? Giant wings to soar through the skies? Webbed feet for swimming through the ocean? This fun, hands-on activity gets kids thinking about how animals adapt to their environments while letting their imaginations run wild!

 

Dive into some penguin science!

In this experiment, kids can learn how penguins stay warm and dry thanks to their super special, water-repelling feathers! Simply draw on paper with a wax crayon, then spray it with water and watch as the droplets roll right off - just like water does on a penguin’s feathers! Older kids can explore the science behind hydrophobic oils and how they help penguins (and other animals) stay dry in chilly waters. We love this simple, hands-on way to bring this concept to life! 

 

All about blubber!

Time to test out nature’s built-in winter coat - blubber! In this hands-on activity, kids can explore how Arctic animals like seals, whales and polar bears stay warm in freezing waters. Simply coat one hand in a “blubber glove” (a plastic bag filled with vegetable shortening) and dip into icy water! This is a brilliant way to introduce kids to the science of heat and insulation while getting them thinking about the incredible ways animals have evolved to adapt to their environments. Science has never been so cool (or should we say, freezing?!)

 

If you’re looking for more activities for this year’s theme, the British Science Week website is also packed with brilliant resources, offering activities for different age groups. Whether you’re a teacher, parent or just looking for some fun STEM ideas, there’s plenty of resources to explore!

But that’s not all! In the spirit of science, we’ve been busy gathering our favourite STEM activities for you to try with kids this science week. So, grab your lab coats and pop on your googles – let’s get experimenting!

 

Our favourite Stem activities to try with kids!

 

DIY volcano

Get ready for an explosive experiment! Kids can have fun crafting their own volcano, then mix baking powder and vinegar for a bubbly eruption - classic kitchen chemistry at its best! A must-try for any science activity list, this one never gets old.

 

Elephants’ toothpaste experiment

Time for a foamy, fizzing science spectacle! The famous elephant toothpaste experiment creates an amazing eruption of fast-moving foam, just like a supersized tube of toothpaste being squeezed! This exciting experiment is a fantastic way to introduce little ones to chemical reactions - just make sure a grown-up helps out with the hydrogen peroxide.

 

Colour changing flowers!

Fancy something fun and colourful? Try this experiment where kids can make their own coloured flowers! Simply take white or light-coloured flowers, such as carnations, and place them into water with different food dyes added. Over time, watch as the flowers change colour right before your eyes! This experiment is not only beautiful but also a great way to teach kids about how plants absorb water.

For older kids, it’s a great opportunity to learn about capillary action - the process by which water moves up through the plant stems. We love this fun and easy way to explore plant biology and colour theory all in one go!

 

Amazing ooblek!

An oldie but a goodie! Making oobleck is so much fun for the whole family. With this easy activity, little ones can enjoy the sensory fun of playing with this taste-safe mix of cornflour and water, while older kids can dive into the science of non-Newtonian fluids and discover how oobleck behaves like both a solid and a liquid!

 

Set sail with a soap-powered boat!

This activity lets kids explore the fascinating concept of water tension in a fun and interactive way. Simply place a small boat on the surface of water, then add a drop of dish soap to the back of the boat and watch it zoom across the water! We love this as a great way for kids to see how surface tension works and how soap can break it, making the boat move. A simple, speedy, science-packed adventure for little explorers!

 

Make your own pH indicator with red cabbage!

This DIY experiment lets kids learn about the pH scale in a hands-on way with one simple ingredient - red cabbage! After making their own indicator solution that changes hue depending on whether it’s mixed with an acid or an alkali, kids can have fun testing common household items and see where they fall on the pH scale - perfect for young scientists eager to explore chemistry in the kitchen!

 

How does heat affect water?

Here's a super simple experiment that shows how warm and cold-water act differently! Simply drop some food colouring into jars of both cold and warm water and watch how the colours move. The warm water will spread the colour faster while the cold water will keep it more contained. This is a fun, visual way for kids to learn about diffusion and how temperature affects the movement of liquids!

 

Build-a-bridge activity!

Calling all aspiring engineers! This STEM building challenge with LEGO bricks is perfect for little builders. Kids can design and construct their own bridges, testing different shapes and structures to see which ones hold the most weight. It’s a fun, hands-on way to learn about engineering, design and the science of strength - all while getting creative and thinking outside the box!

 

The magic egg experiment!

Try this egg in the bottle magic trick for a truly scientific spectacle! All you need is a peeled, hard-boiled egg, a glass bottle with a neck slightly smaller than the egg and a bit of heat. As the air inside the bottle cools, the pressure difference magically pulls the egg right inside! Perfect for kids to discover the principles of air pressure and experience a cool science trick in action (though good luck getting the egg out afterwards!).

 

We hope we've inspired you to try out some fun STEM activities with kids this British Science Week! Teaching children about the wonders of science is so important, and the best part is - it doesn’t have to be complicated! Hopefully this has helped you see that with just a few simple ingredients and a bit of creativity, you can turn everyday moments into exciting science experiments.
