25. Ribiške zgodbe v šoli : priročnik za učitelje tretje triade osnovnih šolLucija Čok, Tina Čok, Urška Bratož, Irina Moira Cavaion, Anna Maria Grego, 2023, dictionary, encyclopaedia, lexicon, manual, atlas, map Abstract: Priročnik Ribiške zgodbe v šoli je namenjen predvsem osnovnošolskim učiteljicam in učiteljem tretje triade, ki bi želeli dopolniti, razširiti in poglobiti vsebine, predvidene v okviru nekaterih obveznih in izbirnih predmetov (etnologija – kulturna dediščina in načini življenja, zgodovina – odkrivajmo preteklost svojega kraja, geografija – raziskovanje domačega kraja (šolskega okoliša) in varstvo njegovega okolja, pa tudi slovenščina in italijanščina …). Ker je bilo ob omenjeni analizi obstoječih učnih načrtov mogoče opaziti izrazito pomanjkanje vsebin, povezanih z (morskim) ribištvom in življenjem ob morju, so v nadaljevanju navedeni nekateri predlogi za intenzivnejše vključevanje obmorskih vsebin v učni proces. Opisani so primeri tematsko prepletenih, toda ločenih učnih enot (o ribištvu, ribiški dediščini, zgodovini predelave rib v obmorskih mestih, terminologiji, povezani z ribištvom, kulinariki v povezavi s floro in favno Sredozemlja in podobne teme), v katerih so poleg okvirne vsebine določeni tudi operativni cilji, način dela, možnosti medpredmetnih povezav ter dodatna gradiva in delovni listi za uspešen izobraževalni proces, kar učiteljicam in učiteljem olajša pripravo učnih ur, načrtovanje projektnega dela in tudi dodatnih pedagoških dejavnosti. Seveda so ti predlogi navedeni samo kot smernice, ki jih učiteljice in učitelji lahko poljubno preoblikujejo.

27. IoT electrochemical sensor with integrated ▫$Ni(OH)_2–Ni$▫ nanowires for detecting formaldehyde in tap waterŠpela Trafela, Abhilash Krishnamurthy, Kristina Žagar, Urška Kavčič, Igor Karlovits, Beno Klopčič, Sašo Šturm, Kristina Žužek Rožman, 2023, original scientific article Abstract: Simple, low-cost methods for sensing volatile organic compounds that leave no trace and do not have a detrimental effect on the environment are able to protect communities from the impacts of contaminants in water supplies. This paper reports the development of a portable, autonomous, Internet of Things (IoT) electrochemical sensor for detecting formaldehyde in tap water. The sensor is assembled from electronics, i.e., a custom-designed sensor platform and developed HCHO detection system based on Ni(OH)2–Ni nanowires (NWs) and synthetic-paper-based, screen-printed electrodes (pSPEs). The sensor platform, consisting of the IoT technology, a Wi-Fi communication system, and a miniaturized potentiostat can be easily connected to the Ni(OH)2–Ni NWs and pSPEs via a three-terminal electrode. The custom-made sensor, which has a detection capability of 0.8 µM/24 ppb, was tested for an amperometric determination of the HCHO in deionized (DI) and tap-water-based alkaline electrolytes. This promising concept of an electrochemical IoT sensor that is easy to operate, rapid, and affordable (it is considerably cheaper than any lab-grade potentiostat) could lead to the straightforward detection of HCHO in tap water.
