Discover the wonders of science with this compact Science Experiment Toolbox, designed for children aged 4 and up! This portable kit contains everything young inventors need to complete six exciting experiments, each demonstrating real scientific principles. Measures 30 x 26.6 x 8.7cm. Ages 4yrs+.How It Works:Open the toolbox and follow the included instruction guide for step-by-step assembly.Conduct each experiment to create moving machines such as a bell ringer, cogwheel sound maker, zoetrope, waving hand, climbing frog, and crane.Encourage creativity by combining components to invent new devices and explore further scientific concepts.Contents Include:Plastic parts: Bolts, nuts, cap nuts, pulleys, cogs, screwdriver, wrench, handgrip, silicone belt, bell, zoetrope, frog, and gasket.Wooden parts: Single-hole cube, triple-holed rectangular block, strips with 5, 7, and 9 holes, and hanger.Soft parts and accessories: Designed for safe, age-appropriate play.Educational Benefits: STEAM Learning: Hands-on experimentation introduces children to science, technology, engineering, art, and mathematics in a fun and engaging way. Physics & Energy Concepts: Explore momentum, energy transfer, potential and kinetic energy, and gravity through interactive play. Problem-Solving & Logical Thinking: Children develop analytical and reasoning skills while assembling, testing, and troubleshooting devices. Fine Motor & Tool Skills: Using bolts, pulleys, cogs, and wooden pieces strengthens hand-eye coordination, dexterity, and safe tool handling. Creativity & Imagination: Open-ended experiments encourage children to invent new machines and explore possibilities beyond the guided activities. Confidence & Independence: Completing each experiment builds self-confidence and a sense of achievement.
