Opposites Attract
Pupils demonstrate the attraction of small pieces of paper to a charged plastic rod and conduct experiment with other objects to determine whether they can hold a charge. They then use online applets to apply their experiments to...
Curated OER
Coulomb's Law
Students solve problems involving electric charges and force. In this physics lesson, student solve word problems using addition and subtraction of vectors. They identify the direction represented by a vector as it relates to an electric...
Curated OER
Coulomb's Law
Ninth graders observe the relationship between electrical charge and force. In this electrical charge lesson students experiment and find the quantitative relationship between force and the center to center distance between objects.
Cornell University
Splitting Water with Electricity
Explore how electricity splits water molecules into hydrogen and oxygen. Learners begin by calculating the voltage necessary to separate the water. They then perform the experiment and measure the ratio of hydrogen and oxygen bubbles.

What Is Electricity
Fourth graders develop an understanding of static electricity and discover how to detect a charge by using electroscopes. In this electricity lesson, 4th graders complete a lab on electricity and discuss the results with the...
Curated OER
Electroscope
Students examine what an electroscope is and who invented it. In this electrical lesson students build their own Emergency Radiation detector Electroscope.
Curated OER
Electromagnets: Winding Things Up!
High schoolers explore solenoids and electromagnets. After building an electromagnet, students use a TI Graphing calculator, a CBL 2 interface and a magnetic field sensor to measure the strength of a magnetic field. They create a graph...

Newton's Theory of Universal Gravitation
High schoolers explore how Newton tied together the gravity observed on Earth and the motion of the Moon. They apply an earlier lesson about centripetal forces.
Curated OER
Electric Current and Circuits
Compare the drift speed of conduction electrons in a current-carrying wire to the signal speed of changes in current. They also distinguish between DC and AC and describe how AC is converted to DC.
