Barometer & rain gauge kit

Visualizes sound waves using physical mediums like water, sand, or a membrane.

This kit demonstrates how fire extinguishers work, teaching fire safety and chemical reactions by creating a simple, safe chemical extinguisher. It provides students with hands-on experience in understanding the science behind extinguishing fires and the principles of combustion.

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.
