This teaching resource provides a comprehensive guide for educators to engage students in exploring the principles of electromagnetism through hands-on activities. Spanning 30 to 45 minutes, the activity involves groups of four students who take on specific roles (Materials Manager, Data Recorder, Hypothesis Leader, and Test Coordinator) while conducting experiments that demonstrate how electricity can create magnetic fields. Essential materials for these experiments include batteries, copper wire, iron nails, and magnets. The guide emphasizes collaborative problem-solving, scientific testing, and data observation as key skills developed during the inquiry. The activities encourage students to create and test their own electromagnets, understand the effects of static electricity, and compare results with peers to identify factors affecting magnetic strength. Reflective discussions and real-world connections highlight the relevance of electromagnetism in various technologies, making the learning experience both interactive and informative.
