1. Learning Task Design for Science KLA Chow Kai Yin Maryknoll Fathers’ School

2. 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

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

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

8. Semi-final
