Students often find chemistry more engaging when the concepts they learn in the classroom are connected to real world applications. Sapling Learning strives to provide questions that not only cover the concepts learned in the classroom, but also questions that apply these concepts to applications students might encounter in their everyday lives. One area where we have recently added questions that apply chemical concepts to real world applications is batteries.
In the spotlight question, which is targeted for use in general or introductory chemistry courses, an image of a Leclanché, or dry cell, battery is given. Students are asked to provide the half-reactions that occur at the anode and cathode during the discharge of the battery under basic conditions. To complete the question, students must take what they have learned about electrochemistry and apply it to the operation of the battery. The electrochemical concepts tested in this question include balancing oxidation-reduction reactions and identifying whether oxidation or reduction occur at the anode or cathode.
This question along with the other new questions on batteries can be found in section 17.5 Electrochemical Applications of the Sapling General Chemistry taxonomy or section 16.5 Batteries in the Sapling Introductory Chemistry taxonomy. To access the library, just follow these instructions from the Sapling Learning help pages. These instructions have details on searching in the library and finding similar questions. Your dedicated Tech TA can also assist in finding questions or providing information on newer questions.
