This NASA video describes how the Wright Brothers used the scientific inquiry in learning to fly. It will demonstrate how their first plane worked. It discusses pitch, yaw, and roll.
This NASA film will discuss how scientists predict the weather and why it is difficult to be 100% accurate. This video also has a section on the different cloud types out there.
This NASA video describes what the sun is and what it is made out of. Part of the discussion is about sun spots and solar flares. They do a great job showing actual video and talk on a younger grade level.
This NASA video demonstrates how scientists compare distances between the planets and the sun using the measurement system, Astronomical Units. They do a great job discussing scaling and why we use AU's as the measurement system when talking about our solar system.
This video was done by NASA education and discusses a little bit about the history of measurement systems. It then moves on to our US standard of measuring and how to calculate distances using it. Finally it discusses the Metric system and how easy it is to use and how to convert between meters and kilometers.
