NASA Connect - The Right Ratio of Rest: Proportional Reasoning



NASA Connect video containing the following four segments. In the first segment of the Right Ratio of Rest: Proportional Reasoning, Lynn Swann gives a summary of the entire video. Next Jennifer Pulley explains to the circadian clock to R. J. and how sleep in space differs from sleep on Earth. The first segment ends with a inquiry based question about Norbert and Zot as they encounter light dark cycles on other planets. In the second segment of the Right Ratio of Rest: Proportional Reasoning, R.J. talks with Dr. Charles Czeisler about what the circadian clock is and what it does in the body. Dr. Charles Czeisler also discusses the factors that influence the circadian clock and the benefits of sleep. In the third segment of the Right Ratio of Rest: Proportional Reasoning, Jennifer Pulley explains three types of rational numbers: Fractions, Decimals and Percents. Jennifer also describes ratios and proportions. In the third segment students at Cole Middle School conduct an activity in which they record and graph sleep data in different ways. The third segment ends with an inquiry based question posed by Derek Wang comparing time on Earth to time on Neptune. In the fourth segment of the Right Ratio of Rest: Proportional Reasoning, R. J. talks with Dr. Dave Williams about the things that interfere with astronauts sleep in space. Dr. Dave Williams tells R. J. what it is like to sleep in space. Later on, R. J. receives a call from Dr. Charles Czeisler, Dr. Czeisler gives R.J. a schedule so that R.J. can get the full amount of sleep that he needs. At the end of the segment Jennifer Pulley reviews what we learned about sleep patterns and rest.
