Now that students have learned about waves, frequency, and energy, it is time to put their knowledge to work! Students will investigate polysomnogram printouts (used by sleep diagnostic centers) that include multiple measurements such as the EEG (brain waves), EMG (leg movement) and EOG (eye movements) taken during an actual sleep study. Since many different bodily function measurements are recorded on the printout, students will learn to identify each line of a polysomnogram, comparing and contrasting the energy each wave represents. Students will be able to extrapolate the stage of sleep just by looking at different wave patterns!
