Journey to the Stratosphere
When a helium balloon is released it races rapidly towards the sky. Does it continue to travel at this speed? Watch the YouTube video of a weather balloon with included telemetry to help answer the question. Students race the balloon, using regression to make predictions for the elevation at 30 minutes. Students check their answers on the video rather than the back of the book. Enjoy the flight and the view as the balloon journeys into the stratosphere.
