When it comes to science experiments, the classic baking soda volcano is a rite of passage.
To keep the learning excitement going beyond the volcano, Sydney Catholic Schools is sharing four fresh, fun, and hands-on ideas to get your child’s interest in STEM (Science, Technology, Engineering, and Mathematics) truly exploding with curiosity.
Whether your child is a budding scientist, tech whiz, builder, or mathematician, these simple activities will spark young minds and make STEM feel lively and accessible – no smoke or lava required.
Science: Kitchen chemistry that bubbles with surprise
Cooking is a fantastic gateway to fascinating science, packed with real-life chemical reactions that kids can see, touch, and even taste!
Instead of the usual baking soda volcano, try making homemade butter by shaking cream in a jar. It’s delightfully messy, hands-on, and a delicious way to watch science come alive right before your eyes. Even better, it’s an experiment you can eat afterwards!
Pro tip: Talk about how movement causes liquids to change form and let your child explore the process hands-on.
Technology: Level up their coding skills
Transform screen time into a powerful creative challenge by immersing your children in coding projects that develop valuable, real-world skills. Platforms like Scratch and Python give teens the opportunity to bring their ideas to life by designing games, animations, apps, or even websites.
These tools blend logical thinking with creativity, encouraging hands-on problem-solving, experimentation, and iterative learning (process with repetitive actions), skills that are highly sought after in today’s digital world. Coding not only sharpens technical abilities but also unlocks new ways to express and innovate.
Pro tip: Take coding offline by writing “programs” for friends to follow, like creating a treasure hunt with step-by-step instructions. Debugging mistakes and improving your code is where the real learning happens!

Engineering: Build it, break it and learn from it
Forge your child’s inner engineer by gathering everyday materials like cardboard, straws, or LEGO bricks to design and build structures with a purpose.
Challenge them to construct a bridge strong enough to hold a toy car. Experimenting with different shapes and supports turns building into an exciting lesson in physics and problem-solving.
Pro tip: Ask, “What happens if we add more support?” or “Why does this design hold better than that one?” to encourage thinking like an engineer.
Mathematics: Unlocking the power of patterns
Maths isn’t just about crunching numbers, it’s the hidden code behind everything awesome in your child’s world. Whether it’s the rhythm of their favourite playlist, the repeating designs in street art, or the stats of their favourite sports team, patterns are everywhere.
Challenge them to spot these patterns and create their own: mix up music beats, design graphic tees, or even get them to hack their gaming strategy using maths. This isn’t just about homework; it’s about unlocking a fresh way to see the world and boosting their problem-solving superpowers.
Pro tip: Use apps or tools that visualise patterns, like music mixing software, graphic design programs, or sports analytics apps, to help teens see maths in action. Encouraging them to experiment hands-on makes abstract concepts real and sparks creativity.
Catalyst for curiosity
Unleash your child’s inner Einstein with everyday moments at home that are bursting with discovery, creativity, and fun. At Sydney Catholic Schools, we believe learning doesn’t stop at the classroom door – by bringing these fresh ideas to life, you’re helping your child build the skills and confidence to become a curious, capable problem solver.
An emphasis on excellence in all areas of education – from academic to vocational, sport and the arts – helps Sydney Catholic Schools nurture the potential of all students in their 147-strong network of primary and secondary schools.
