Design of a Door Alarm
How does electricity work? Budding scientists explore the concepts of electrical currents and open and closed circuits with class discussion and a hands-on activity using a battery to turn on a light bulb. Learners also make predictions...
Curated OER
Circuit City
Fifth graders are introduced to the concept of circuits and how electricity works. In groups, they design their own subdivision with houses in which they have inside and outside light sources. To end the lesson, they make the circuits...
Curated OER
Lemon Battery
Students construct their own battery made of lemons. In this electrochemistry lesson, students explain why lemons conduct electricity. They perform a series of experiments to investigate its conductivity.
Curated OER
Brown Bag Science
Students discover, through the discovery method, how electricity works. They construct a simple circuit and a parallel circuit, make an electrical motor work and add a switch to turn it on and off.
Curated OER
Battery Type and Size
Students identify the different types of batteries available in the market. In this science lesson, students discuss how to select the right batteries for a car.
