3 Fun Science Experiments to Try at Home
Science is not just about memorizing facts and formulas—it’s about curiosity, discovery, and experimentation! You do not need a fancy lab to conduct exciting science experiments. Here are three fun, hands-on activities you can try at home using simple materials. Get ready to explore scientific concepts in an engaging way!
Magic Milk Experiment
What You Need:
- A shallow dish or plate
- Full cream milk
- Food colouring (multiple colours)
- Dishwashing liquid
- Cotton swabs
Steps:
- Pour enough milk into the dish to cover the bottom.
- Add a few drops of different food colouring into the milk.
- Dip a cotton swab in dishwashing liquid.
- Touch the milk’s surface with the soapy swab and watch the colours swirl!
Science Behind It:
Milk contains fat molecules, and dishwashing liquid breaks down these molecules. As the soap spreads, it pushes the food colouring around, creating a mesmerizing explosion of colour. This demonstrates surface tension and the interaction between fat and soap.
Baking Soda and Vinegar Volcano
What You Need:
- A small bottle or cup
- Baking soda
- Vinegar
- Dish soap
- Food colouring (optional)
Steps:
- Place the bottle on a tray to catch spills.
- Add 2 tablespoons of baking soda into the bottle.
- Add a few drops of food colouring and some dish soap.
- Pour in vinegar and watch the eruption!
Science Behind It:
The reaction between baking soda (a base) and vinegar (an acid) produces carbon dioxide gas, creating the foamy eruption. This is a great way to visualize chemical reactions in action!
Invisible Ink with Lemon Juice
What You Need:
- Lemon juice
- A cotton swab or paintbrush
- White paper
- A light source (lamp or candle)
Steps:
- Squeeze lemon juice into a small bowl.
- Use a cotton swab or paintbrush to write a message on the white paper.
- Let the juice dry completely.
- Hold the paper close to a heat source (like a lamp or candle, with adult supervision) and watch the message appear!
Science Behind It:
Lemon juice is slightly acidic and weakens the paper fibres. When heated, it oxidizes and turns brown, revealing the hidden message. This is a cool example of oxidation reactions in chemistry.
These simple yet exciting science experiments make learning fun and interactive. Whether you are exploring surface tension, chemical reactions, or oxidation, each experiment helps you understand key scientific principles in an engaging way. Try them at home and see science come to life!
