How much sleep do I really need? Do daytime activities such as yoga, exercise, or caffeine affect my sleep? Do nighttime activities such as screen-time, journaling, or reading affect the time it takes for me to fall asleep? Birches School students probe these and other interesting questions in a classroom-wide sleep and journaling project. Join us at the 2017 Cambridge Science Festival and Carnival on April 15th from noon to 4pm as we outline the details of crafting a questionnaire, designing a protocol, and analyzing group data. We’ll help you to make your own sleep journal!
