From the chemist's point of view, the loss on ignition of the sample is a historical parameter that is directly related to the content of organic matter in the soil sample and it is used to rating soils or solid fertilizers. Loss on ignition is also directly related to the total carbon content, which is another similar parameter that can be determined in the laboratory. This paper is aligned to the analysis of the possible transforming the methods of solid samples analysis into a form, which is usable in the chemistry teaching. The possibilities of applying mathematical methods to the analysis of the relationships between the above parameters are discussed and the use of such a procedure as an interdisciplinary project in education at various types of schools is discussed.","PeriodicalId":194970,"journal":{"name":"Proceedings of the Conference on the Didactics of the Sciences DidSci+ 2021","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127303302","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
