Question

1. maria was having trouble falling asleep at night. some nights she would lay awake for hours, whereas other nights she fell right to sleep. sofia suggested that she keep a sleep journal to help her discover what made her fall asleep faster. maria wrote down her activities for each day, along with if she stayed awake and for how long. maria noticed that on days when she had pe she fell asleep with no problems. she wondered if increased physical activity would help her fall asleep faster. hypothesis: (increased or decreased) physical activity causes __________________. if i _________, then i will fall asleep in (more or less) time than when i ___________.

Explanation:

A hypothesis is an educated guess. Maria noticed that on days with PE (physical education, which implies increased physical activity) she had no trouble falling asleep. So the first part of the hypothesis should be about increased physical activity. The second part should state the effect, which is falling asleep faster. For the "If - then" statement, the "If" part is doing the action (increased physical activity) and the "then" part is the result (falling asleep in less time compared to when there is less physical activity).

Answer:

Hypothesis: (Increased) physical activity causes falling asleep faster.
If I increase my physical activity, then I will fall asleep in (less) time than when I have less physical activity.
