Science Activity: Stnd 01 Date Standard 01: 8.PS2.1 Magnetism and Electricity Design and conduct an investigation about magnetism and electricity. Examine factors that increase or diminish the electric current and the magnetic field strength. Key Focus: Science and Engineering Practice(s) Develop and Use Models Key Focus: Crosscutting Concept Recognize cause and effect relationships

(Generating Electricity) Electromagnetic Induction (Generating Electricity) These devices are commonly called generators. Magnets and a coil of wire can induce (generate) electricity The magnet has to move through the coil (solenoid) … or the coil has to move through the magnet. To Increase/Decrease the Electrical Current: (1) Move it faster or slower (2) Add or remove coils.
