Kidrise STEM Educational Wooden Model Toy: Hydraulic Excavator
This Kidrise STEM hydraulic excavator wooden model is an educational toy designed specifically for Hong Kong schoolchildren. More than just a toy, it's a miniature engineering laboratory. Through hands-on assembly and operation, children can intuitively understand the principles of hydraulic transmission in physics, transforming abstract scientific theories into tangible practical experiences—the perfect starting point for nurturing future engineers and scientists.
🔬 Core Scientific Principle: Hydraulic System
The core of this model lies in its sophisticated hydraulic control system . The principle is as follows:
Each end of the hose is connected to a syringe, forming a closed power transmission loop. When the syringe in the control area is pushed or pulled, the internal liquid (or air) pressure is quickly transmitted to the syringe at the other end, converting the pressure into kinetic energy to drive the robotic arm. The model has three independent hydraulic components, which control the excavator's lifting, extension, and digging actions, perfectly simulating the operating logic of real construction machinery.
🌟 Product Features and Educational Significance
- STEM deep learning: encompasses elements of science, technology, engineering, and mathematics, and strengthens interdisciplinary thinking.
- Tool-free safety design: Utilizing high-precision laser cutting technology, all environmentally friendly wooden parts are pre-cut. No scissors are needed , significantly reducing assembly risks and allowing children to explore in a safe environment.
- Logic and endurance development: The process of assembling parts into the whole structure can effectively train spatial imagination, hand-eye coordination and patience in problem-solving.
- Environmentally friendly materials: Made of high-quality plywood, it has a warm touch and no odor, giving parents peace of mind and children a happy experience.
🔧 Assembly difficulty: Medium (Suitable for family outings, estimated assembly time is about 45-60 minutes)

How to Choose Age-Appropriate Toys?
Struggling to find the right toy or birthday gift? Kidrise has the perfect guide for you!
Toys are essential partners for children to learn while playing. Regardless of the type, they hold educational value.
However, choosing toys that do not match a child's age may lead to disinterest or safety concerns.
Kidrise Expert Advice:
Match the child's developmental age (intelligence, motor skills, and physical ability). Choosing 'slightly challenging' toys can better stimulate a child's potential.
