4th Grade Physical Science Activity.
4.1.4 Experiment with materials to identify conductors and insulators of heat and electricity.
4.1.5 Demonstrate that electrical energy can be transformed into heat, light, and sound.
Adaptions: have the ELL and special need students (as well as whole class in order not to single out students) draw a demonstration of how + & - affect each other before doign the experiment in oder to enhance understanding of what the objects represent in regards to their charge.
Extensions: You can extend this activity to younger get students by using balloons and rubbing them on their heads. Also, draw a demonstration showing the charges. Then, have the students determine how the positive charge of the balloon affects different items.
