Weeks 8, 9 & 10-

Build and Wire!

This week:

1. 1. 1. 1. Complete construction of the model building with electrical components.

Remember each group will need to provide their own extra component. (E.g. motor, buzzer etc from jaycar)

1. 1. 1. 1. Calculate the cost to run electricity, per day, week and month (show relevant website as evidence of the cost of electricity)

3. Prepare a presentation for your project

Building Model and working electrical circuit

Requirements for your circuit:

two light bulbs and holders (provided)

one other component (for example a buzzer, or motor/fan) which you will need to supply.

wire and alligator clips (provided) which will be used to connect your house circuit to a power pack.

You will also need to make your own switch/es

Make sure you watch this video on how to wire your houses!👇🏼

Equipment List:

Each group will be provided with

Wire - 2 meters

Power pack

2 globes and 2 globe holders

Alligator clips x 2

Paper fasteners x 6

Paperclips x 3

A3 Sheets of cardboard

You will also use wire cutters, masking tape and scissors.

BYO your Jay Car component!

Remember you can only use the 2 m wire provided no extra.

Your house model can be no bigger than 30 cm by 40 cm and a maximum

height of 12 cm.

Most equipment can be obtained from your science teacher,

but you will need to organise your own third component and bring it to class.

Presentation!

Your presentation should include information that:

Describes how working in groups helped complete this project (four examples)

Provides a detailed description of new relevant skills learned during the project (four examples)

Includes a detailed description of two major problems you encountered, and a description of the processes used for each to resolve them.

Discusses and shows the uses of each component and room.

Justifies the building's purpose and design and relates to function.

Evaluates how it is a cost-effective building to help your named social purpose

Evaluates how much it will cost to run the electricity👇🏼in the building using referenced websites to justify the cost...

THIS VIDEO WILL SHOW YOU HOW TO ATTACH WIRE TO YOUR ALLIGATOR CLIPS!

1. Carefully snip the plastic off the end of the wires.

2. Twist wires together tightly.

3. Unscrew the screw (lefty loosey) so the screw is slightly elevated off the clip.

4. Feed the wires through the long tube-like part of the alligator clip, make a hook so you can feed the wire through the hole near the screw.

5. Wrap the wires under and around the screw in a clockwise direction.

6. Screw your screw back into place (righty tighty).

You should now have a path for the electrons to travel!
