Content Focus:
Stage 3 of the Physical World strand focuses on the difference between contact and non-contact forces and how energy is transformed from one form to another. Students are provided with an opportunity to investigate how electrical energy can control movement in products and systems. Stage 3 of this strand develops students’ abilities to design, test and evaluate a product or system that demonstrates energy transformation, further developing an understanding of the interrelationship between force and energy.
Skills Focus:
Working Scientifically
Questioning and predicting
|
Design and Production
Producing and implementing
|
Inquiry and Focus Questions:
Describing and exploring specific forces
How can we make a force stronger or weaker? |
Transfer and transformation of energy
What types of energy transformations can be observed? |
Students:
- friction and air resistance - tension and elastic force - gravity - magnetism - buoyancy
- how increasing or decreasing the strength of the force of air resistance by changing the shape of an object results in increases or decreases in speed |
Students:
- heat energy to light energy
Forces and energy in products and systems
How can energy be used in a product or system? Students:
- a microphone transforms sound energy into electrical energy - a solar panel transforms light energy into electrical energy
