If a researcher watches one-week-old babies and records how many times they open and close their eyes while lying in their cribs, he is most likely using:
 
  the case-study method.
  a controlled experiment.
  cross-sectional research.
  scientific observation.

Question 2

If a scientist wanted to use scientific observation to see how frequently schoolchildren share food at lunch, she could:
 
  give half of them candy and see how many would share.
  mingle with the children and ask them about sharing.
  bring a small group into her laboratory and observe them eating.
  watch the children from an unobtrusive spot in the school lunchroom.
