Easy Science Experiments to Try at Home


This article will share fun and easy science experiments that kids can do at home. We will show how science can be super fun and how kids can learn cool things by doing simple experiments with stuff they find around the house. We want to make science exciting for kids and easy for parents and teachers to share.

 

MAKE A VOLCANO IN YOUR KITCHEN


Making a baking soda volcano in your kitchen is a fascinating scientific experiment with the added "wow" effect of an explosion.


Ingredients/Materials


  • 3 to 7 cups warm water
  • Red food colouring
  • 5 drops dishwashing detergent
  • 2 tbsp. baking soda
  • 2 cups white vinegar


Supplies/Tools


  • Empty soda bottle (2 litre depending on how big you want your volcano)
  • Baking pan or large tray
  • Funnel


Instructions


1.  Create Your Volcano Structure


Place the plastic bottle in a baking pan or large tray and mould your volcano around it using play dough.

Whichever technique you choose to create your volcanic cone, be sure to keep the bottle opening free of material. Use the bottle cap or cover the opening with tape to prevent any material from getting in the bottle.


2.   Load Your Volcano

 

Using the funnel, fill the bottle two-thirds full with warm water and a few drops of food colouring. Add the dishwashing detergent and baking soda to the liquid in the bottle and give it a gentle stir.

 


   3. Prepare for the Explosion


Before adding the final ingredient, make sure that you're wearing some sort of protection over your eyes. Keep your face away from the volcano as the mixture may shoot up quite a bit, especially if you used a smaller bottle.

As precisely as possible (without using the funnel), pour the vinegar into the bottle and get ready for your miniature-sized volcanic eruption.


Try different amounts of vinegar. Try different amounts of baking soda. Try different sized and shaped bottles.


CREATE RAINBOW IN A GLASS

 

Ingredients


Sugar, water, food colouring, and 5 glasses or clear plastic cups.


INSTRUCTIONS


  1. Arrange five glasses in a row. 1 tablespoon (15 g) sugar in the first glass, 2 teaspoons (30 g) sugar in the second glass, 3 tablespoons (45 g) sugar in the third glass, and 4 tablespoons (60 g) sugar in the fourth glass. The fifth glass is still empty.


 

 

Add 3 tablespoons (45 ml) of water to each of the first 4 glasses. Stir each solution. Each solution should be stirred. If the sugar does not dissolve in any of the four glasses, add another tablespoon (15 ml) of water to each.

Fill the first glass with 2-3 drops of red food colouring, the second with 2-3 drops of yellow food colouring, the third with 3 drops of green food colouring, and the fourth with 3 drops of blue food colouring. Each solution should be stirred.


Now, utilizing the various density solutions, let's create a rainbow. Fill the remaining glass about a quarter of the way with the blue sugar solution.


Layer some green sugar solution on top of the blue liquid with care. Put a spoon in the glass, just above the blue layer, and slowly pour the green solution over the back of the spoon.


If you do it correctly, you won't affect the blue solution at all. Fill the glass halfway with the green solution.

Using the back of the spoon, place the yellow solution on top of the green liquid. Fill the glass three-quarters of the way.


Finally, pour the crimson solution on top of the yellow liquid. Fill the glass up to the brim.


 

MAKE A BOUNCY EGG

 

Supplies Needed


  •    Raw Egg
  •    Clear Glass or Jar
  •    White Vinegar


Instructions


  1.  Place an egg carefully into a jar.
  2.  Fill a jar with vinegar until the egg is fully covered.


  1.  Leave egg for 24 hours, then drain the old vinegar and add fresh vinegar.
  2.  Check on the progress each day and note how the egg changes.
  3.  After three days, carefully remove the egg from the jar and rinse with water.


The egg will now look translucent, and the yolk can be seen from the outside. Allow your child to gently “bounce” the egg from a small height, about 6 inches or less.


PLAY WITH STATIC ELECTRICITY USING A BALOON

 

What You Need

• 2 balloons

• Light string, thread, or curling ribbon

• Wool fabric (socks, mittens, or sweater)

• Gift tissue paper

• Aluminium can (empty, on its side)

 

Instructions

1. Blow up the balloons and tie a light string to each


2. Hold a balloon by the string (it should be hanging down) and bring the balloon close to each of the materials (the second balloon, the tissue paper, and the aluminium can).


 

         

3.Rub both balloons onto your hair or onto the wool fabric.

Why parents must approach education as a long-term investment – Advtech Choosing a school for your child will be one of the most complex and consequential decisions parents will ever make. When parents choose a school for their child, the decision is often shaped by immediate needs: convenience, reputation, or results in the senior years. Yet schooling is not a short-term decision. It is one of the longest and most formative investments a family will ever make, stretching over 12 to 15 years or more, from early childhood development through to Form 4 and further study. Darren Purdon, Head of Advtech Schools Academics, says the real value of education lies not in isolated moments of achievement, but in the intentional construction of learning over time, and that parents should approach their child’s educational journey intentionally, from start to finish. “Education depends on interconnected building blocks, each phase deliberately designed to prepare learners for the next,” he says. Parents should therefore carefully consider the elements that underpin a successful, lifelong educational journey before making this important decision. FOUNDATIONS MATTER Learning does not begin in Standard 1. It starts far earlier, in Kindergarten, where children develop the cognitive, social, emotional, and language skills that will underpin their entire academic journey, Purdon says. “When these early years are thoughtfully planned, children are more likely to arrive in the Foundation Phase confident, curious, and ready to learn. When they are not, gaps emerge that can widen over time. If the foundations are secure, progress accelerates, as we see in our Advtech Schools where we utilise international best practices and benchmarks to personalise early learning.” THE IMPORTANCE OF BELONGING Academic success is deeply connected to emotional safety and a sense of belonging. Children learn best when they feel comfortable at school, when they feel seen, supported and happy. And when teachers are supported, engaged, and professionally fulfilled, that sense of wellbeing naturally filters into the classroom. When students are excited about going to school, engagement increases, persistence improves and learning deepens. Social and emotional learning and supportive classroom environments with caring teachers underpin deep learning. Advtech schools include experienced psycho-social specialists to continually ensure teachers are upskilled in managing diverse classrooms. RESPONSIVE TEACHING AND TECH Effective education is not defined by what has been taught, but by what has been learned. “At Advtech schools, there is a growing shift toward instructional models that prioritise responsiveness. If learners have not grasped a concept, the expectation is not to move on regardless, but to re-teach using different strategies until understanding is achieved,” Purdon says. Additionally, technology has become a powerful enabler of this responsiveness, but not as a replacement for teachers. “AI-assisted tools, and classroom digital platforms such as Advlearn, increasingly act as classroom assistants, helping teachers identify learning gaps quickly and accurately. These tools provide insight into where students are struggling, allowing teachers to personalise support and adjust instruction accordingly.” INTENTIONAL SUBJECT PATHWAYS Consistency and coherence across subjects are another critical component of long-term value creation in education. “Take Mathematics as an example. Mathematical competence is not built in isolated units or single phases, it requires a carefully sequenced programme that develops conceptual understanding, fluency and confidence year after year,” says Purdon. “An intentional approach ensures that each phase prepares students for what follows, creating a golden thread that runs from early numeracy through to advanced problem-solving in the senior years. Gaps are far harder to close when this thread is broken.” The same principle applies across subjects: literacy, science, languages, and beyond. “Strategic curriculum alignment therefore ensures that learning compounds rather than resets each year, and parents should keep this in mind when strategizing their child’s educational journey.” CHOOSING A SCHOOL WITH THE LONG VIEW For parents, the key question should not only be “Is this a good school now?”, but rather “Is this a school that understands the full journey, as well as understands where my child excels and needs support in each subject?” “Advtech Schools value long-term academic growth, student wellbeing, teacher development, and intentional curriculum design offers far more than short-term results. It offers continuity, stability, and a clear vision of success from the earliest years through to matric,  ” Purdon says. “And in an education landscape that continues to evolve, the most trusted institutions are those that recognise schooling not as a series of isolated years, but as a curated journey, using regular academic data to personalise learning and shape student success for life.”

In a rapidly changing world, education can no longer be defined by textbooks alone. It must inspire, challenge, and ignite a lifelong love of learning. At the heart of this transformation is a simple but powerful belief: every student deserves a place where curiosity is not only welcomed—but deliberately cultivated. In Botswana, this idea is increasingly shaping how leading institutions think about education. Nowhere is this more evident than in the recent evolution of Gaborone International School (GIS), whose rebranding reflects more than a refreshed identity. It signals a deeper commitment to aligning environment, philosophy, and student experience in ways that are both contemporary and grounded while being underpinned by an unwavering commitment to quality education At its core, a school must first be a place where students feel secure, known, supported, and understood. Pastoral care, often understated in conversations about academic success, plays a defining role in this. At GIS, there is a growing emphasis on ensuring that each student is seen not just as a learner, but as an individual navigating both academic and personal development. Structures that support wellbeing, mentorship, and open communication create an atmosphere where students feel safe to take intellectual risks. Curiosity, after all, thrives where there is trust. This sense of care is balanced by a strong culture of discipline, one that is not imposed for its own sake, but cultivated as a framework for growth. Discipline, in this context, is about consistency, accountability, and respect. It teaches students to manage their time, honour commitments, and engage constructively with challenges. Rather than restricting curiosity, it gives it direction, ensuring that exploration is purposeful and sustained. Equally important is the role of tradition and culture in shaping the school environment. Even as GIS embraces innovation and modernisation, it remains anchored in values that promote respect, integrity, and community. A diverse, international student body brings with it a richness of perspectives, and the school’s culture encourages students to both celebrate difference and find common ground. In this balance between global outlook and local relevance, students develop a broader understanding of Botswana, the world and their place within it. The physical environment reinforces these values. Purpose-built science laboratories, collaborative learning spaces, robotics labs, and digital hubs provide students with the tools to explore ideas beyond theory. These spaces are not simply about access to technology, they are about creating opportunities for hands-on, inquiry-driven learning. Supporting this is a philosophy that recognises that each student’s learning journey is unique. The integration of adaptive technologies and responsive teaching methods allows educators to tailor learning experiences, ensuring that students are both challenged and supported. This personalised approach moves beyond standardised expectations, focusing instead on helping each learner reach their full potential. At the center of it all are educators who understand that their role extends beyond instruction. They guide, mentor, and challenge students, encouraging them to think critically, ask better questions, and engage deeply with their learning. Ongoing professional development ensures that teaching remains dynamic, informed by global best practices while rooted in the needs of the local context. What emerges from this alignment of care, culture, discipline, and innovation is an environment that feels both structured and open. Students are given the freedom to explore, within a framework that supports their growth. They learn not only to question the world around them, but to do so with responsibility, empathy, and purpose. The rebranding of Gaborone International School, then, can be understood as a reflection of this balance. It is not about changing direction, but about clarifying intent, about creating a school experience that is as attentive to character as it is to capability. Because when students are supported holistically, when they are cared for, guided by values, and equipped with the right tools, curiosity does more than flourish. It becomes the foundation upon which confident, disciplined, and compassionate individuals are built.

A New Beginning Walking into high school for the first-time marks more than your first day of school; it marks the first step into a community that believes in shaping not only your mind, but your character. As you walked into this hall, you became part of a school that stands firmly on three pillars: Generosity, Integrity, and Self-Discipline . These words are not decorations on a slide; they are the heartbeats of our culture. They describe the kind of person we hope you will become and the kind of student who thrives here. 2. Generosity: The Strength of a Giving Heart Generosity is more than sharing what you have; it is sharing who you are . It shows in the small, everyday actions: offering help when no one asks, listening when a classmate struggles, choosing kindness even when it is not the easiest choice. As your orientation programme highlights, you are entering a community that values being helpful, warm-hearted, considerate, and thoughtful. Generosity builds trust, and trust builds strong teams, friendships, and classrooms. “We rise by lifting others.” 3. Integrity: Doing What Is Right, Even When Unseen Integrity is the quiet voice inside you that says, “Be honest. Be sincere. Be the best version of yourself.” It is the foundation of responsibility, whether that means completing your assignments truthfully, respecting school spaces, or carrying yourself with honour in every interaction. Your presentation reminds you that integrity is about honesty, uprightness, sincerity, and trustworthiness. When integrity guides your choices, people learn they can rely on you, and more importantly, you learn to rely on yourself . “Integrity is choosing courage over comfort.” 4. Self-Discipline: The Driver of Your Success Self-discipline is the ability to manage your thoughts, your behaviour, and your emotions so that you can reach your goals. It is showing determination in your studies, balancing your work and activities, and staying consistent even when distractions feel tempting. In this school, self-discipline is not imposed; it is developed. It grows each time you set goals, follow instructions, respect routines, greet teachers, take care of your environment, and take responsibility for your own learning, just as the orientation sessions will guide you today. “Discipline is the bridge between goals and accomplishment.” 5. What These Three Values Look Like in Daily Life Here at GIS, these values take shape in very practical ways: Generosity shows when you include others, support your classmates, and contribute positively during group work. Integrity shows when you follow the code of conduct, wear your uniform with pride, and uphold the standards introduced to you today. Self-discipline shows when you manage your time, focus during lessons, and commit yourself to excellence, in academics, in sports, and in behaviour. Together, these values do more than make you a good student; they help you become a grounded, confident, and capable young person. 6. Closing: The Journey Ahead As you begin this new chapter, remember that GIS is not only a school, but also a community where you will grow, learn, and discover who you are becoming. The expectations set out today are not barriers; they are pathways. Pathways designed to help you develop character, build resilience, and walk confidently toward your future. Carry generosity in your actions, integrity in your decisions, and self-discipline in your journey. Here at GIS, who you become matters just as much as what you achieve. Welcome to your new beginning.
