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 instructional activity, student solve word problems using addition and subtraction of vectors. They identify the direction represented by a vector as it...
