Redox and Electrochemistry
In this redox and electrochemistry worksheet, students identify the anode in electrode pairs of electrochemical cells. They also describe how a lemon battery works and how wet and dry voltaic cells work.
Curated OER
Electrical Energy
Students compare and contrast a cell and a battery. In this physical science instructional activity, students explain how they create energy. They conduct an experiment to apply what they have learned in this instructional activity.
Chymist
Batteries
Young scientists study the construction of a battery through experimentation. They engage in five experiments which combine to create a thorough study of the history of batteries beginning with a model of the first battery.
Curated OER
DNA Extraction
In this DNA extraction worksheet, learners learn how to extract DNA from various foods. Students complete 2 short answer questions.
Curated OER
History of the Battery
Students study the development of batteries. For this electrochemistry lesson, students compare the different types of batteries. They explore its applications especially in the medical field.
Curated OER
Electrical Battery
Young scholars investigate the different types of batteries and how they work. In this energy lesson students experiment with batteries and see which ones last the longest.
