🧪 Science Experiments
Hands-on experiments you can try at home with everyday materials. Each one teaches real science — simply explained.
Physical Science
Drop household objects into water and discover which ones sink and which ones float — and find out why!
Rub a balloon on your hair and watch tissue-paper butterflies magically leap into the air!
Test everyday objects with a magnet and sort them into magnetic and non-magnetic — then test if magnetism passes through materials!
Track how a stick's shadow moves throughout the day and build your own ancient sundial to tell the time!
Use a glass of water and sunlight to split white light into all the colours of the rainbow — no special equipment needed!
Build the tallest freestanding tower using only 10 sheets of paper and tape — then test it with a book on top!
Chemistry
Mix baking soda and vinegar to create a fizzing, foaming volcanic eruption — and learn why acids and bases react!
Drop food colouring into milk, touch it with a soap-coated cotton swab, and watch an explosive burst of colour!
Layer four coloured sugar-water solutions of different densities in a glass to create a stunning rainbow that doesn't mix!
Write a secret message with lemon juice — it's invisible when dry, but heat the paper and your message magically appears!
Soak a raw egg in vinegar for two days and watch the shell dissolve — leaving a soft, rubbery, see-through egg!
Hang a string in a saturated salt solution and watch beautiful cubic crystals slowly grow over three to five days!
Biology
Watch a bean seed sprout inside a glass jar — see the root grow down and the shoot grow up day by day!
Wrap a clear bag around plant leaves and watch water droplets appear — proof that plants release water vapour into the air!
Build a working lung model from a plastic bottle and balloons — push and pull to see exactly how your diaphragm powers breathing!
Count your heartbeats before and after exercise to discover how your heart speeds up to deliver more oxygen to your muscles!
Earth Science
Tape a bag of water to a sunny window and watch evaporation, condensation, and precipitation happen in miniature — your own tiny water cycle!
Use hot water, ice, and a tiny spray of hairspray to create a real cloud inside a glass jar — and find out how clouds form in the sky!
Build a layered filter from stones, sand, and cotton wool to clean muddy water — and learn how water treatment plants work!
Pour water over bare soil and soil with plants and compare the runoff — see how plant roots protect the earth from washing away!
