Competency Goal 3: The learner
will make observations and conduct investigations to
build an understanding of magnetism and electricity. |
Objectives
3.01 Observe and investigate the pull of magnets on
all materials made of iron and the pushes or pulls on
other magnets.
3.02 Describe and demonstrate how magnetism can be
used to generate electricity.
3.03 Design and test an electric circuit as a closed
pathway including an energy source, energy conductor,
and an energy receiver.
3.04 Explain how magnetism is related to electricity.
3.05 Describe and explain the parts of a light bulb.
3.06 Describe and identify materials that are conductors
and nonconductors of electricity.
3.07 Observe and investigate that parallel and series
circuits have different characteristics.
3.08 Observe and investigate the ability of electric
circuits to produce light, heat, sound, and magnetic
effects.
3.09 Recognize lightning as an electrical discharge
and show proper safety behavior when lightning occurs.

Glossary
- Attract- the result of two objects being pulled toward each other
- Circuit- a complete path that through which electricity flows easily
- Circuit breaker- a reusable switch that protects circuits from dangerously high currents
- Compass- a small magnetic needle that turns freely and indicates direction by pointing towards the earth's north pole
- Conductor- a material through which electric current passes easily
- Current- when electricity flows through a wire or some conductor
- Current electricity- a moving electrical charge
- Discharge- the sudden movement of an electric charge from the object where it built up to another nearby object
- Electricity- a form of energy caused by the motion of electrons and neutrons
- Electromagnet- a magnet made when electric current flows through a wire
- Energy- a quantity that describes the capacity to do work; a source of usable power
- Filament- a very fine wire or thread (tungsten) that sits in the middle of a light bulb that glows and produces light
- Force- a quantity that tends to produce movement or acceleration of a body in the direction of its application; a push or pull - any push or pull that makes an object start moving, stop moving, speed up, slow down, or change directions
- Generator- a machine that uses an energy source and a magnet to make electricity
- Glass mount- the object that holds up the filament in a light bulb
- Heat- the movement of thermal energy from warmer to cooler objects
- Insulator- a material through which electric current does not pass easily
- Lightning- a discharge of static electricity from a huge cloud called a thundercloud
- Magnet- an object that pulls iron and steel things to it
- Magnetic field- the space around a magnet where magnetism acts
- Magnetism- the force around a magnet
- Parallel Circuit- a circuit that connects several objects in a way that the current for each object has its own path
- Pole- one of two ends of a magnet where the magnetism is strongest
- Repel- push away from each other
- Resistance- how well electricity flows through a material
- Series Circuit- a circuit that connects several objects one after the other so that the current flows in a single path
- Static electricity- the building up of electrical charges on a material (ex. Rubbing two pieces of material together) because negative charges have moved from one material to another
- Switch- a device that can open or close an electric circuit
