Visualize the fluid motion of convection cells! Here's everything you need to do this activity. Have you ever really listened to a ball bounce? Exploratorium staff physicist Thomas Humphrey describes the elegant mathematics of a bouncing ball. Exploratorium staff physicist Thomas Humphrey explains what temperature and color have to do with one another. An introduction to the Ice Balloons activity, in which learners explore globes of frozen water and learn how to ask and then answer 'investigable' questions. A detailed demonstration of how to do the Ice Balloons activity, including a discussion of materials needed and strategies for getting learners to ask and then investigate questions about what they are seeing. The science and pedagogy behind this activity, including a discussion of concepts such as density, temperature, thermal conductivity, center of mass, freezing point depression, heat capacity, and the characteristics of the states of water, water vapor, and ice. Also describes strategies for observing, asking questions, and then choosing a question to investigate further. To understand how Earth’s climate system has changed over time, scientists need to find, develop and use natural recorders of temperature and precipitation. One natural thermometer comes in the form of alkenones: trans-fats produced by certain algae. How does the interaction of solar radiation on sea ice effect climate change?
Please join us as we chat live with Dr. Don Perovich, an expert in the fields of albedo effect, and sea-ice mass balance on climate.
Join us as we talk with Dr. William Fry, emeritus professor at Stanford University and the father of gelotology, the study of humor and laughter, and their effects on the human body. Join Exploratorium biologist Karen Kalumuck as she experiments with enzymes and proteins and shows at what temperatures they function best.
