Lesson 1: New topic on Electricity. Brainstorm all that you can think of to do with Electricity. Think about what you use electricity for every day and imagine you lived 200 years ago and what life would be like without it - write an account of 1 day without electricity. Give some ideas of how to use electricity safely and what not to do when using electricity. Find out what is an electrical conductor and an insulator, give 4 examples of each.

Lesson 2: P114, 115 and 116 textbook: Know that a complete circuit is required for electricity to flow, and that this flow is called current and measured in Amperes or Amps (symbol A). Copy the table of components and symbols on P116 into your book. Know that current is not "used up" and is the same everywhere in a series circuit. Describe a switch and what it might be used for in a circuit.

Lessons 3-5: Know what electrical resistance is and how it affects flow of current in a circuit. Series and pararllel circuits - how to connect them, how they work and what happens to lightbulbs and ammeters when they are connected in series and in parallel. P117-120 textbook

Lesson 6: Voltmeters; know that a voltmeter measures the potential difference and therefore the energy given up in a component in a circuit. Voltmeters measure this in Volts (symbol V). P 120-121 in textbook.
Know that voltmeters must be connected in parallel and ammeters in series.

Lesson 7: Plugs - know the wiring and what a fuse is and why we use a fuse. Know how to wire a plug practically.

Lesson 8-9: Testing fuses practical - know about different types of fuses and their uses in electrical appliances. Also know about electricity in us - how electricity is important in our nervous impulses, heartbeat (pacemaker) and muscle contraction.



Lesson 10: test on electricity

New Topic - 7K Forces
This topic should cover an introduction to forces including the ideas and practical applications of gravity, upthrust, uneven and balanced forces. Students should know the terminology associated with forces, eg, mass, Newtons, weight, density, non-contact and contact forces etc as well as the different types of push and pull forces and how they act on an object.
The textbook has comprehensive notes and questions to answer on each double page, so I would like the students to work through the entire chapter on forces (chapter 7K) themselves, making notes on any sections they do not understand entirely. They can then either contact me through this wiki site (the e-mail or discussions sections allow this) or they can wait until we get back to school. Looking forward to getting stuck into the practical with you all when we get back!!

Extension work on forces to be completed after the work from the textbook is finished:-
- attempt the following and complete the designs/investigations NEATLY in their exercise books;
1) Analyze a water park in terms of its use of force.
2) Design a container to protect a raw egg from the force of a fall from a designated height.
3) Design an experiment to investigate if heavy and light objects fall at the same speed... Think about what you will change (1 thing only!), what you will keep the same and what you will measure.
