Jet sings a song about not giving up when he and his friends are having a hard time solving a problem in this short clip from the PBS KIDS show Ready Jet Go! They are looking for a set of wheels for Jet 2 so he can move on the rocky surface of Mars. They try all sorts of things, but none of them work! Sydney’s mom, Dr. Skelley, encourages them not to give up and to keep trying because that’s what scientists do.
