On 3 August 2009, we learnt about accretion and subtraction from Dr. Syarmila. Then, we are asked to do two cubes which combined together that shown accretion and subtraction. The elements that have been eliminated in the subtraction cube (A) should be included as a design in the accretion cube (B). Besides, the cubes must contain light bulb. After that, we are asked to build a black box which acts as energy generator by Mr. Wan Burhanuddin.
