The authors propose using an overhead stirrer in school chemistry settings – a device that simplifies the preparation of reagent solutions and enhances student engagement in project-based and research activities. The stirrer is easily assembled and programmed using the LEGO MINDSTORMS EV3 kit. The article details the steps for assembling and programming the device, as well as its application in a laboratory experiment involving the synthesis of nanomagnetite. It also discusses the use of this stirrer and other devices based on robotics kits in school projects.
