Act 5:
Act 5:
Design Situation
9-year-old Helen and 7 year old Mariela live in a mountain at remote village in Bolivia. Their typical day starts at 5am in the morning where they walked 2.5 hours to school through the dense jungle in Bolivia. The girls live in extreme poverty as does 60% of the Bolivia's rural population. Helen and Mariela dream of leaving their homes to live a better life when they grow up. Helen dreams of becoming a doctor and Mariela wants to own her own farm. Education is the only way out of their poverty. Everyday, children in Bolivia travel long distance on foot to their school. Often, they must travel in the dark through the jungle. There are no lights available for them.
Design Brief
To design and make an electronic light tag for children in Bolivia so that it can be used as light markers to help them travel to school safely.
Design Specifications
1. The electronic light tag must be made of acrylic.
2. The electronic light tag must have a design theme of transport or superhero.
3. The electronic light tag must have at least one light emitting diode (LED) and a coin cell battery.
Ideation : Shape borrowing
Every design starts with an idea. Ideate using 2D sketches through:

Act 6: Development
Act 6: Development
(In view of the limited time, you can skip the paper mock-up in Act 6. Instead, draw your circuit diagram in your journal)
From your 18 designs, choose one for further development. You will need to do the following:
Refer to the sample below to design your circuit.
Use cardboard, paper clip, LED and copper tape to build your mock-up circuit.
Complete your production flow chart and production plan.
Paste your mock-up in your design journal (Pg 14).
Act 7: Prototype of your electronics light tag
Act 7: Prototype of your electronics light tag
In Act 7, you will need to build a prototype of your mock-up using the following:
Acrylic, switch, wire connectors, CR2032 battery and LED.
Refer to the following video for practical process
