It's About Time

Welcome to It's About Time! In this event, teams will answer questions related to time and they may construct and bring one non-
electrical device that triggers a single signal to occur three times at equally spaced time intervals.

The information below should not be interpreted as an extension of the rules. You can find free online copies of the current rules for download on the 2023 Rules page of the Science Olympiad website. The official rules in the current Rules Manual take precedence.
