Determine which characteristic of batteries—capacity or stability—poses the greater challenge.
Students are introduced to two significant challenges to developing batteries to meet the needs of storing the potential energy generated by solar and wind power—capacity and stability. Students use information about electrolytic and electrochemical cells to determine which challenge is more significant.
Assess your students’ ability to:
Decide which changes to water power technology have increased the efficiency of hydro power the most.
Does a hydroelectric dam satisfy Kirchhoff’s laws?
Illustrate how various forms of generating electricity interact with the geosphere, atmosphere, ecosphere, and hydrosphere.
