Mr.Yeung

Electricity unit:

Use this page to guide you along with all the necessary items for the Unit.

Unit Project:

• Build the following:
• For 60% build both a series and parallel circuit with 3 light bulbs, at least 1 switch, and battery power.
• For 80% build above plus the loop the loop
• For 100% build above plus the “Operations” game.

Assessment:

• Demonstrate by building a series or parallel circuit
• The Project outlined above
