Poll

Where are you on the learning scale?

• Level 1

  Identify the elements of a closed circuit (5.P.11.1, 5.P.11.2)

• • Level 2

  • Compare and contrast closed and open circuits (5.P.11.1)

  • Recall that some materials conduct energy better than others (5.P.11.2)

• • Level 3

  • Investigate and illustrate the fact that the flow of electricity requires a closed circuit (a complete loop) (5.P.11.1)

  Identify and classify materials that conduct electricity and materials that do not (5.P.11.2)

• Level 4

  Design and conduct an investigation that requires the transformation of energy to improve something that currently uses a form of energy. Explain how this could improve any current objects that use energy. (5.P.10.1, 5.P.10.2, SC.5.P.10.4)

I can investigate and illustrate the fact that the flow of electricity requires a closed circuit (a complete loop) (5.P.11.1)

I can identify and classify materials that conduct electricity and materials that do not (5.P.11.2)
