Geology to touch and grasp! In this excavation set from Kosmos, children set out with hammer and chisel in search of colorful and fascinating treasures of nature. Hammering, scratching, digging - layer by layer they work their way through the soft plaster block and different, colourful minerals such as rock crystal, rose quartz, amethyst, aventurine and a red jasper come to light. The clear and illustrated instructions show exactly how to proceed. Just like a professional in research, the children clean and document their finds and can then display them in their room. Of course, the booklet also contains additional information about minerals and stones, and those who are looking for a nice place to store their new treasures will also find what they are looking for here. A Kosmos experimental kit for children from 7 years that makes science come alive.
