Inquiry-based activities covering the basics of electricity. Perform a variety of hands-on investigations to study the properties of electricity. Students will explore the concepts of electric currents, open and closed circuits, and series and parallel circuits. They?ll also investigate static electricity using an electroscope. The students will apply the knowledge gleaned from these activities to classify materials as either conductors or insulators of electricity and electrical power. Your students will understand concepts of electrical charge, current, resistance and voltage. Understand the concept of electric circuit and power. Distinguish between resistors in series and parallel. Classify materials as electrical conductors or insulators. Identify cases from everyday life where electricity is being used. Class Size: 40 Students. Grades 7-10

Teach your students basic problem-solving skills! Challenge them to develop and test a hypothesis which determines the ideal environmental conditions for specially encapsulated sponge animals to emerge from their "cocoons". In the process, they learn the basics of how scientists design experiments, control variables, gather information, summarize and present data, and solve scientific problems. Grades 7-10
