In the photo, two people partake in building the word “participate” out of LEGOS. To participate means to partake in something and contribute to it. That could be anything like participating and helping out in a project, or participating in helping the community. This image relates to “Participate” not because the blocks spell out that word, but because the two people at the end partake in building the word, block by block. Participation can also beget improvement the more you partake and contribute, so the blocks in each letter can also symbolize improving bit by bit.
