Linda called a space museum to see if she could find out about astronauts and their low
gravity environment. She also went to the library to read about gravity.
Linda noted that without water the spools of thread on a string stand tightly against each
other. With water, the spools float upwards and their is some separation between them. Linda measured
how much string was left when spools were not and were in water. She wrote these observations and
measurements in her notebook.
The woman at the space museum said she could try an experiment. These are the steps Linda
A. Cut the bottom of a two-liter bottle.
B. Place 6 spools of thread on an 18 cm string.
C. Attach the string to the bottle cap and then turn the bottle upside down (cap
end down, cut off bottom up).
followed
D. Hold the other end of the string up and watch what happens.
E. Fill the two liter with water from the cut off bottom.
F. Hold the other end of the string again and watch what happens.
Linda and her class learned that gravity is a force the pulls objects towards the center of
Earth. If gravity palls everything down, then bow does gravity effect human height?
Linda learned that the spools of thread spread out and took up more length of the string in a
low gravity environment. If the spools of thread were like the spinal column in a human, then, in a low
gravity environment, the discs would spread out and a person would be taller.
After studying her background information, she thought that gravity probably does effect
human height.
