In this unit, students will compare various materials and ways to produce DC voltage using chemical reaction. They will conduct experiments to become familiar with circuitry and connections. Students will compare cost versus power, along with the advantages and disadvantages of common types of cells, batteries, and other energy sources. Students will also explore producing power through alternative materials. Students will design and build their own batteries.
Throughout this unit, students will also learn and explore new vocabulary terms and types of electrical connections used in the electronics field. By taking electrical measurements and doing calculations, students will integrate mathematics and science into their knowledge and understanding of electronics.
Students will work in groups of three to four to research and collect information and data, perform experiments on common types of cells/batteries, and design their own batteries. Throughout the unit, students will contribute to a project notebook that will contain their research, notes, time log, and tasks performed. The students will answer the essential question by presenting their findings and completed batteries to a panel. They will compete with other groups to design the best battery in several categories.
