It was agreed that the CSD 's multi-year programme of work CSD 11 would be organized on the basis of seven two-year cycles , with each cycle focusing on selected thematic clusters of issues derived from the WEHAB initiative . As of the beginning of July , Earth 's surface was still vibrating from the 2004 quake , each cycle moving the ground up and down about 0.5 micrometer every 20 minutes or so . Students spend a portion of each cycle designing , performing , and analyzing the results of their own project . PCR involves a repetitive series of temperature cycles , with each cycle comprising three stages : denaturation of the guiding template DNA to separate its strands , then cooling to allow annealing to the template of the primer oligonucleotides , which are specifically designed to flank the region of DNA of interest , and , finally , extension of the primers by DNA polymerase . The programme is organised on the basis of seven two-year cycles , with each cycle focusing on selected thematic clusters . We define each cycle consisting of instrumental and consummatory activities a double interact to highlight the fact that there are two interlocked behaviors , namely an instrumental activity ( i.e. the bug posting activity ) being interlocked into an initial activity ( i.e. the testing activity ) and a consummatory activity ( i.e. enjoying a non-misbehaving program ) being contingent onto the bug fixing activity . It was agreed that the CSD 's multi-year programme of work beyond 2003 would be organized on the basis of seven two-year cycles , with each cycle focusing on the five key thematic areas of water , energy , health , agriculture and biodiversity ( WEHAB ) .
