Students use potatoes to light an LED clock (or light bulb) as they learn how a battery works in a simple circuit and how chemical energy changes to electrical energy. As they learn more about electrical energy, they better understand the concepts of voltage, current and resistance.
Students experientially learn about the characteristics of a simple physics phenomenon the pendulum by riding on playground swings. They use pendulum terms and a timer to experiment with swing variables. They extend their knowledge by following the steps of the engineering design process to design timekeeping devices powered by human swinging.
This resource is from Tools4NCTeachers.In this lesson, students explore telling time to the hour and half hour. Students have opportunities to use math vocabulary as they explain why half hours are halfway between two hours.
This lesson is from Tools4NCTeachers.In this lesson, students are introduced to telling time to the hour and are given opportunities to explore the concept using both analog and digital clocks.
