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.
Secret Spell Scroll
Children invent a symbol code, write a hidden spell in white wax crayon and reveal it with watery paint. They learn how a substitution cipher works and why wax resists water, so the paint only soaks into the bare paper.
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.
Pumpkin Seed Scientists
Scooping out a pumpkin becomes a science lesson: guess how many seeds are inside, count them in tens, test which ones sink or float, and save some to grow next spring. It covers estimating, counting and how plants make seeds.
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.
🔒 PremiumGhost Story Stop-Motion
Moving a model ghost a tiny bit between each photo and then playing the photos quickly creates the illusion of movement, the same trick used in animated films. Children plan a short story, practise patience and learn how frames per second work.
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.
Balloon Ghost Zip Line
When air rushes out of the back of the balloon, it pushes the ghost forward along the string. That is Newton's third law in action: every push has an equal push the other way, the same idea that launches real rockets.
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.
Glowing Jack-o'-Lantern Jar
Turns an empty jam jar into a pumpkin lantern and shows the difference between translucent materials, which let light glow through, and opaque ones, which block it and make the face shapes.
🔒 PremiumClimbing Spider String Toy
Pulling the strings one at a time makes the spider climb because the angled straws grip the string with friction on one side and slide freely on the other. It is a hands-on way to explore forces, friction and angles.
