Rhonda watched a video taken by a camera that was lifted into the upper atmosphere by a weather balloon. she saw the balloon pop when it reached a certain height. afterward, rhonda wondered what effect the air pressure at high altitudes has on the volume of gas in balloons. what scientific practice is rhonda performing?

The scientific practice that Rhonda is performing could be described as a scientific method in which she follows steps in order to conclude or analyze the results that she wants to find out or the experiment that she has been doing. This involves the observation in which she watches the video and could lead into the next steps such as hypothesis, experimentation, reports and conclusion that could lead her into solving how the reaction had happened.

Neptune is the eighth planet from the sun. it was the first planet to get its existence predicted by  mathematical calculations  before it was actually seen through a telescope on sept. 23, 1846. irregularities in the orbit of  uranus  led french astronomer alexis bouvard to suggest that the gravitational pull from another celestial body might be responsible. german astronomer johann galle then relied on subsequent calculations to   spot neptune via telescope. previously, astronomer galileo galilei sketched the planet, but he mistook it for a star due to its slow motion. in accordance with all the other planets seen in the sky, this new world was given a name from greek and roman mythology — neptune, the roman god of the sea.
