Thanks to the transparent column, children can clearly see the individual filter layers and how the water flows through the materials, gradually removing coarse impurities.
Assemble the 6 filter parts, add pebbles, sand and activated carbon, and observe the differences. Ideal for developing curiosity, logical thinking and a connection to nature.
The box includes the filter parts, filtration media and instructions, so you can start experimenting right away. The accessories make measuring and handling the materials easier.
The SES Creative set from the Explore range offers a simple, hands-on experiment that helps children understand how water filtration works in nature and in practice. Just fill the individual filter sections with the included media, pour in water (e.g., from a stream or pond) and watch as impurities are trapped in the different layers.
The transparent column lets you observe the whole process step by step, making it ideal for at-home discovery as well as school projects. Children learn to experiment, compare results, and gain basic awareness of environmental protection.
