Week 1

Google Meet: Wednesday 11:20am

This week is a short week so we will only have three lessons. We are starting our new topic, Electricity and Magnetism. We will spend the next 10 weeks (all of Term 2) on the topic, hopefully having our test in Week 12 of Term 2.

I have uploaded the mahi kāinga book materials, all of the worksheets, the textbook activities and linked to the notes for this topic in Google Classroom so that you can find them whenever you need. As usual I will distribute the answers to the mahi kāinga book as we go through the topic.

  1. Static Electricity

    • Work through the static electricity notes
    • Make copies of diagrams
    • Answer the questions.
    • Complete questions 1-4 on Worksheet 1 - Statics & Fields
  2. Conductors & Insulators

    • Work through the notes for charge and current, these notes include conductors and insulators.
    • Complete questions 1-5 on Worksheet 3 - Voltage, Current and Resistance
  3. Charge & Current

    • Complete questions 1 and two from Activity 18A in the textbook
    • Compete Question 2a from the Mahi Kāinga Booklet

Week 2

Google Meets: Wednesday 11.20am, Thursday 2.10pm

  1. Voltage & Power

    • Read through the voltage and power notes & answer the embedded questions
  2. Resistance & Ohm’s Law

    • Read through the notes & complete the embedded questions
    • Complete Q1-5 on Worksheet 3 if you found them hard last week and got stuck
    • Complete Q1 on Worksheet 5 - Circuits. This will require you to use all the equations you have learned so far!
  3. Series & Parallel Circuits

    • Read through the notes & complete the embedded questions
    • Complete Question 7: 12V Lamps in the Mahi Kāinga Book - DC Electricity

Week 3

Kia ora, everyone!

Going forwards I would like to see more of us on the scheduled Meets. From here on in we are entering new territory, so it is important that we all take the time to engage. My thanks to those of you who have been putting in the effort to attend regularly so far!
