Engaging Science Experiments for Primary Classrooms
Bringing science into the primary classroom can often be a daunting task, but the secret lies in turning abstract concepts into tangible experiences. Science experiments are the perfect tools for this transformation, providing students with the opportunity to explore, hypothesise, and discover the world around them. Below, we present a series of experiments designed to captivate and educate, each aligning with key learning outcomes. For more resources and ideas, you can explore detailed guides on Australian Teacher.
1. The Magic of Invisible Ink
Experiment Overview:
Invisible ink isn’t just for spies and secret agents; it’s also a fantastic way to introduce students to chemical reactions. By using simple household items like lemon juice, students can create their own hidden messages and reveal them using heat.
Materials Needed:
- Lemon juice
- Cotton swabs
- White paper
- Heat source (like a light bulb or a hairdryer)
Instructions:
Students will use a cotton swab dipped in lemon juice to write a secret message on paper. Once the paper dries, they can reveal their hidden message by gently heating the paper, watching as the invisible writing turns brown.
Learning Outcomes:
This experiment introduces students to basic chemical reactions and the concept of oxidation. It’s an exciting way to discuss how certain substances change under heat, sparking conversations about everyday chemistry.

2. Erupting Volcanoes: A Classic Experiment
Experiment Overview:
Few experiments captivate young learners like the classic baking soda volcano. This activity demonstrates chemical reactions, pressure build-up, and gas release in a visually stunning way.
Materials Needed:
- Baking soda
- Vinegar
- Dish soap
- Red food colouring (optional)
- A model volcano (or a simple mound of sand or play dough)
Instructions:
Students build a volcano model and place a mixture of baking soda, dish soap, and food colouring inside the crater. When vinegar is poured into the volcano, the mixture erupts, creating a foamy display.
Learning Outcomes:
This experiment illustrates the basics of chemical reactions between acids and bases. It’s an engaging way to introduce geology concepts and discuss real-world volcanic eruptions.

3. The Power of Static Electricity
Experiment Overview:
Static electricity can be a fascinating concept for young learners. Using a balloon, students can explore the effects of static electricity in a hands-on way, learning about electric charges and forces.
Materials Needed:
- Balloons
- Small paper pieces or tissue paper
- Woollen fabric or your hair
Instructions:
After inflating the balloon, students will rub it against their hair or woollen fabric to generate static electricity. They can then observe as the balloon attracts small paper pieces, demonstrating the forces at work.
Learning Outcomes:
This simple experiment helps explain the basics of electric charges and attraction, making it an excellent introduction to physics concepts for primary students.

4. Rainbow in a Glass: Exploring Density
Experiment Overview:
Creating a rainbow in a glass is a stunning experiment that visually demonstrates density and how different liquids interact based on their mass.
Materials Needed:
- Sugar
- Water
- Food colouring
- Four clear cups
- A spoon
Instructions:
Students will create solutions with varying sugar concentrations, each coloured differently. Carefully layering these solutions in a glass reveals a beautiful rainbow effect, illustrating the concept of density.
Learning Outcomes:
This experiment allows students to explore density, solubility, and the properties of liquids in an engaging, visually appealing way.

5. The Expanding Soap: A Microwaving Marvel
Experiment Overview:
Using a bar of soap, this quick experiment demonstrates how air pockets and water molecules react when exposed to heat, resulting in a surprising transformation.
Materials Needed:
- Ivory soap bar (must be Ivory for best results)
- Microwave
Instructions:
Students place the bar of soap on a microwave-safe plate and heat it on high for about a minute. The soap will expand, resembling a cloud as it transforms before their eyes.
Learning Outcomes:
This experiment is perfect for discussing the states of matter, particularly how heat affects gases trapped within the soap. It’s an eye-catching way to explore physical changes.
