  1. electricity static electricity grounding electric current circuit resistor Lesson 4 Splash

  2. What is static electricity? Lesson 4 a

  3. How can electricity flow? A circuit is formed when an electric current passes through an unbroken path of conductors. Lesson 4 b

  4. What kinds of circuits are there? series circuit parallel circuit Lesson 4 c

  5. How can you use electricity safely? Lesson 4 d

  6. Vocabulary A _______________ is formed when an electric current passes through an unbroken path of conductors. _______________ is the movement of electrons. _______________ is the buildup of charged particles. Electricity Static electricity static electricity circuit electricity Lesson 4 Vocab Review a

  7. Vocabulary _______________ is a flow of electricity through a conductor. An object in an electrical circuit that resists the flow of electrons is called a _______________. _______________ occurs when a conductor shares its excess charge with a much larger conductor. Electric current Grounding electric current resistor grounding Lesson 4 Vocab Review b

  8. An object rubs against another object or surface. Sequence What happens as objects rub together and form sparks? Electrons are exchanged. The buildup of electrical charge attracts the electrons to protons in the other object. The electrons discharge through the air, creating a spark End of Lesson Lesson 4 GO Review

  18. How can magnets produce electricity? axle turbine water in water out As the coils spins next to magnets, high-voltage electricity is generated. Lesson 5 c

  19. What is magnetic levitation? train magnets track magnets Lesson 5 d

  20. Main Idea What happens when a bar magnet is cut in half? Two bar magnets are formed, each with a north and south pole. Lesson 5 Main Idea Review

  21. Vocabulary _________________ is the lifting of an object by means of magnetic forces. The directional lines of the magnetic forces around a magnet are called the _________________. _________________ is electric current that rapidly changes directions. Magnetic levitation Alternating current magnetic levitation alternating current magnetic field Lesson 5 Vocab Review a

  22. Vocabulary An electric circuit that produces a magnetic field is called an _______________. _______________ is the ability of an object to push or pull on another object that has the magnetic property. A _______________ is a device that creates electric current by spinning an electric coil between the poles of a magnet. Magnetism magnetism generator electromagnet Lesson 5 Vocab Review b
