Projects
Mummified Apple Experiment
Children test how the ancient Egyptians preserved mummies by burying apple slices in salt and bicarbonate of soda for a week. The salts draw water out of the apple, and without water the things that cause rot cannot grow. It is a real fair test with measuring and recording.
Crispy Meringue Ghosts
Whisking egg whites traps thousands of tiny air bubbles, and sugar holds them in place so the foam stands in ghostly peaks. Slow baking dries the foam into a crisp shell. Children see a liquid turn into a foam and then a solid.
Frozen Monster Hand Rescue
Children rescue toy spiders trapped in a frozen monster hand, finding out that salt and warm water melt ice faster than cold water. It is a sensory way to explore melting, temperature and testing ideas.
Dancing Tissue Ghosts
Rubbing a balloon on hair or a woolly jumper builds up static electricity, which pulls the tiny tissue ghosts up off the table so they seem to rise and dance on their own.
Bubbling Cauldron Potion
Mixing bicarbonate of soda with vinegar makes a gas called carbon dioxide, and a squirt of washing-up liquid traps it in bubbles so the potion foams up and over the cauldron like a witch's brew.
🔒 PremiumUnder-the-Sea Jelly Aquarium
Making jelly shows how a warm liquid sets into a wobbly solid as it cools, and suspending fruit 'fish' introduces the idea of setting things in layers.
Shoebox Solar Oven
Children explore renewable solar energy and heat absorption by building a simple oven that traps light and converts it into thermal energy. This introduces fundamental thermodynamic concepts such as insulation, reflection, and radiation in a delicious, hands-on way.
Moon-Crater Impact Tray
Dropping balls into a tray of flour shows how meteorites smashing into the Moon made its craters, and lets you test how the size and drop height of a space rock changes the crater it leaves.
Marker-Pen Tie-Dye Shirt
Watching marker ink spread through fabric with a splash of rubbing alcohol shows how liquids carry colour along fibres, making swirling firework patterns.
Eggshell Cress Heads
Seeds need only damp cotton and light to sprout — and cress grows fast enough to watch.
Bean in a Jar
Seeds sprout roots and shoots — you can watch a plant begin, up close.
🔒 PremiumWormery in a Jar
Worms mix and tunnel through soil — you can watch them build layers and help the garden.
