Magnetism and Electricity

Unit Review Sheet

Facts and Definitions

Lesson 1: The Power of Magnets

• Magnetism vocabulary: attract, magnetic field, magnetic poles, repel, force

Lesson 2: Experimenting with Magnets

• Magnets come in different shapes, sizes, and strengths.
• Magnetic force can be transferred from a magnet to a magnetic object.

Lesson 3: Magnetic Fields

• All magnets have a magnetic field.

Lesson 4: Magnet Action

• Magnets are found in many items people use in their everyday lives.
• Magnets can attract and repel other magnets, depending on which poles come into contact.

Lesson 5: Magnetism on Earth

• The Earth is surrounded by a magnetic field.

Lesson 6: Exploring Electricity

• Electricity vocabulary: atom, circuit, electricity, conductor, current, electron, proton, static electricity

Lesson 7: Conductors and Circuits

• Electricity flows in a loop.
• Materials through which electricity does flow are called conductors and those materials through which electricity does not flow are called insulators.
• A switch stops and starts the flow of electricity.

Lesson 8: Motors and Batteries

• Many electronic items have motors.
• In a series circuit, the components are connected, one after the other, in a single loop.
• In a parallel circuit, the electrical current is split into two or more pathways or loops.
• Batteries come in a variety of sizes.

Lesson 9: Products of Electricity

• Electricity can produce light, heat, and sound.
• An electromagnet is an object that acts like a magnet, but its magnetic force is created and controlled by electricity.
• An object with an electrical current also has a magnetic field.

Lesson 10: Sources of Electricity

• Lightning is one of the most dangerous forces in nature.
• Power sources include nuclear power, solar power, fossil fuels, and wind power.
