Paper kite

Demonstrates hydraulic principles using fluids to lift objects, suitable for physics lessons on pressure.

A Lung Model Kit is a hands-on educational tool that demonstrates the anatomy and function of the human lungs and respiratory system. It is widely used in classrooms, science labs, and homes to teach students about the mechanics of breathing, lung structure, and how air flows in and out of the lungs. This model typically includes components to illustrate how the lungs expand and contract, making it an engaging, interactive way to understand respiratory biology.

A Biofilter Kit is a sustainable filtration system that uses natural biological processes to purify water or air. This kit is commonly used to demonstrate concepts in environmental science, such as the nitrogen cycle, biological filtration, and ecosystem management. Through microorganisms or beneficial bacteria, the biofilter breaks down contaminants, making it an ideal tool for understanding water or air purification.
