Are students expected to complete the entire experiment, including all data and all trials, and not make up or extrapolate data for points they do not have time to take?

Yes, students are expected to complete the entire experiment, including all data and all trials, and not make up or extrapolate data for points they do not have time to take. Par 4 "Any student not addressing the assigned question or topic area will be ranked behind those who do, because not conducting an experiment is a violation of the spirit of the event."
