Kosmos Kristalle Züchten (10-14)

New growing methods and an abundance of experimental material - this large crystal growing set from KOSMOS is full of creativity and possibilities! Children from 10 to 14 years can create their own sparkling world: Shimmering individual crystals are created overnight, glittering crystal caves are made by you, plaster figures can be covered with a magical, crystalline shell and, as a highlight, noctilucent crystals sparkle in the little treasure chest. The instruction booklet in the experiment kit uses clear pictures to explain how the marvels are produced in various experiments and shows how the size, colors and shapes of the growing crystals can be influenced or how they can be grown in a single thread. The follow-up pages of the instructions contain a lot of interesting information about natural crystals. A creative and exciting way to discover the STEM science of chemistry!
