Food
How astronauts prepare suitable food
Freeze-drying
At least two of the ways astronauts meet psychological needs
following routines, exercising, relaxing, spending time with others, or enjoying their surroundings
In the microgravity of the ISS, settling is not a good way to separate mechanical mixtures because
no gravity to pull the denser sand to the bottom
What is something we breathe daily?
What is oxygen?
Two foods or drinks that astronauts eat

The steps to make a filter.
build a filter, calculate the efficiency of filters, then calculate how many filters are needed
How food freeze-dries
freezing and then warmed under vacuum pressure to remove wate
how astronauts exercise
they use a stationary bike, a treadmill, and a specially designed weightlifting machine
To prevent microbial growth and manage pH in the ISS water recovery system, this element is used
Silver (or iodine)
HARD BONUS: astronauts test oxygen filters by
using advanced, automated monitoring systems, rather than manual tests, to ensure the air is safe and properly filtered.
