 • I can recall the different types of energy and give examples 

 • I can describe the energy changes involved in a range of common situations 

 • I can define the term system 

 • I can recall that energy cannot be created or destroyed 

 • I can use describe how kinetic energy changes over time 

 • I can recall the units needed for Ek = ½ mv2 

 • I can rearrange Ek = ½ mv2• I can use Ek = ½ mv2 

 • I can use describe how elastic potential energy changes 

 • I can recall the units needed for Ee = ½ ke2 

 • I can rearrange Ee = ½ ke2 

 • I can use Ee = ½ ke2 

 • I can use describe how gravitational potential energy changes 

 • I can recall the units needed for Ep = mgh 

 • I can rearrange Ep = mgh 

 • I can use Ep = mgh 

 • I can use describe how objects have different specific heat capacities 

 • I can recall the units needed for ΔE = mcΔθ 

 • I can rearrange ΔE = mcΔθ 

 • I can use ΔE = mcΔθ 

 • I can use define power 

 • I can recall the units needed for P = E/T 

 • I can rearrange P = E/T 

 • I can use P = E/T 

 • I can recall the units needed for P = W /T 

 • I can rearrange P = W/T 

 • I can use P = W/T 

 • I can recall that energy cannot be created or destroyed 

 • I can describe what happen to wasted energy 

 • I can recall ways to reduce wasted energy 

 • I can describe how insulation can reduce energy loss 

 • I can describe why a system might not be 100% efficient 

 • I can describe whys to increase the efficiency of a system 

 • I can recall the units needed for Efficiency = useful energy out/ total energy in 

 • I can rearrange Efficiency = useful energy out/total energy in 

 • I can use Efficiency = useful energy out/total energy in 

 • I can recall the units needed for Efficiency = useful power out/ total power in 

 • I can rearrange Efficiency = useful power out/ total power in 

 • I can use Efficiency = useful power out/total power in 

 • I can state the different sources that can be used to get energy 

 • I can determine if a resource is renewable or finite 

 • I can consider the impact that using these resources has on the environment 

 • I can discuss the advantages and disadvantages of each source of energy
