Why was the scientist able to survive in an airtight (closed) space with plants?
Write a claim:
This is an actual headline from a newspaper:
Living in a box: Scientist to spend 48 hours in an airtight container with 160 plants to keep him alive.
The scientist survived! He set up an experiment where he collected data before and during the time he was spending the 48 hours in the container. Throughout the study, the scientist kept the lights on and measured carbon dioxide, oxygen, and humidity (water in the air). Here we will look at three sets of data from this experiment.
