Supplier's note

1. Key Breakthroughs:

   • Wood Construction: 20% lighter than plastic alternatives, ensuring ease of handling for children.
   • Adjustable Pulley: Enables dynamic demonstrations of force ratios, unmatched by fixed-design kits.
   • Safety Finish: Non-toxic coating exceeds ASTM F963 safety standards, protecting young users.

2. Version Selection Guide:

   • Base Model: Ideal for introductory STEM activities (e.g.,幼儿园 classrooms) where simplicity and safety are priorities.
   • Advanced Model: Targets elementary students, offering enhanced load capacity for experiments like lifting small objects.
   • Pro Model: Designed for older children or advanced learners, its 4:1 ratio and 3kg capacity enable complex physics demonstrations (e.g., comparing work and energy).

With the Pro Model’s 4:1 mechanical advantage, you can lift heavier loads effortlessly—perfect for exploring real-world engineering scenarios. The Base Model’s lightweight design ensures toddlers can engage safely, while the Advanced Model bridges the gap with moderate complexity. Choose based on the user’s age and learning goals!
