Codes & signals is a 4th grade science skill in the Waves & Information region of the TernQuest map — wave patterns, seeing with light & codes. It is aligned to California Common Core standard 4-PS4-3. Children work through 0 grade-tagged questions at the reason level (reasoning it through), and Pip the tern offers a hint — never the answer — when they get stuck.
How does it unlock?
