Cambridge Lower Secondary PhysicsStage 9 Forces and energy Checklist

Learning objectives

• 9Pf.01I can use density to explain why objects float or sink in water.
• 9Pf.02I can describe the difference between heat and temperature.
• 9Pf.03I know that energy is conserved, which means it cannot be created or destroyed.
• 9Pf.04I know that thermal energy always transfers from hotter regions or objects to colder ones, and that this is called heat dissipation.
• 9Pf.05I can describe thermal transfer by conduction, convection and radiation.
• 9Pf.06I can explain how evaporation causes cooling.
