Transportation: Cars, bicycles, buses.
Household: Appliances, heating, lighting.
Industry: Manufacturing processes, power plants.
-
Positive impacts: Renewable energy, sustainability.
Negative impacts: Pollution from fossil fuels, nuclear waste.
-
Simple experiments to demonstrate types of energy (e.g., using a rubber band to show potential and kinetic energy).
Projects: Building a simple solar oven, constructing a basic electric circuit.
