Example: Go Up, Stay High (GUSH)Science Design Project
• Design a flight device and a launcher
• Judge by the time that the flight device stays in air
• Restrictions:– height not exceeding 5 m– maximum mass of flight device is 0.3 kg– no chemical or electrical device

Stages
1. Preliminary design and preparation
6 weeks • KF (discussion)
2. Prototype production and trial flights
2 weeks • Making the device• KF (discussion)• Semi-final contest
3. Modifying and testing of the product
2 weeks • Refining the device• KF (discussion)• Final contest

Problem of the week for KF discussion
Week 1 Launching mechanisms and launching principles
Week 2 What determines the time taken for an object to reach the top of its flight?
What determines the time for an object to fall to the ground?
Week 3 How can one ensure the object will fall back to the same location
Week 4 Design rocket and launcher to maximize the height
Week 5 Design features of the rocket to maximize the fall time
Week 6 Fabricate the model during the Easter holiday
