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.

A device that tests conductivity in various materials to classify conductors and insulators.

Teaches pH measurement and acid-base properties using pH indicators and solutions.
