INVESTIGATING CONDUCTIVITY

(Grades six and up)

GOALS OF INVESTIGATING CONDUCTIVITY

• The child will discover how an electric current follows a path from a power source to a light bulb and return to the power source effecting an electric circuit.
• The child will discover the principles of electrical conductivity.

OBJECTIVES OF INVESTIGATING CONDUCTIVITY

The child will:

• Explore relationships among a battery, copper wires and light bulbs.
• Be able to explain in his or her own words the difference between Direct Current and Alternating Current.
• Be able to explain in his or her own words that an ampere or amp is a unit measure of electricity.
• Measure in amps, using the milliammeter, the electrical output of the battery used in the milliammeter.
• Discover and measure with the milliammeter the degree of electrical conductivity of various solids and liquids found in the child's environment.
