Step by Step
6 An electrical diagram told the young researchers where to place each of the kit’s parts on the circuit board.
7 The do-it-yourself kits included diodes.
8 Additional parts perform other jobs. Those functions make electronic circuits work in radios—and lots of other electronic devices.
9 The radio’s pieces didn’t just snap into place. Each had to be soldered (SAAH-derd) to the circuit board.
10 The students patiently soldered parts in place. Even so, the process was sometimes tricky. “Trying not to burn myself was really hard,” noted 13- year-old Isabella O’Brien of Canada.
11 Getting everything into place at the same time got awkward, too. “I had a couple of parts that weren’t physically touching the board,” says 13-yearold Raghav Ganesh of San Jose, Calif. “It’s like you needed some sort of third arm to make it easier.”
