What Is Wrong With Me?

• Directions
• Work with a partner.
• Read the scenario.
• Each partner should have a paper labeled with the
  above heading, name, date, block
• Work together to list the symptoms
• decide what is wrong with the person in the
  scenario.
• Use may use The Developing Child textbook to back

• Hi, My name is Mary. When I got up this morning
  to go to work, I did not feel well. I had a mild
  ache in my lower abdomen and a very full feeling.
  I feel very tired and a little faint. I told my
  husband that I think my period is late. I hope I
  am not diabetic because I have to urinate
  frequently. I have noticed for the last few days
  that my breasts are swollen and tender and are
  causing me discomfort. I also have been feeling
  nauseous and I had to throw up right before I
  left for work. What could be wrong with me? I
  need your help to diagnose my problem.

32
Name That Month

• Directions
• Class will be arranged into nine groups.
• Each group will receive one case study strip.
• Each group will read the case study (table tent)
  together to decide which month of the pregnancy
  is described.
• Be ready to share your response.

33
Case Study 1

• The zygote is the size of a pin head. The egg is
  attached to the lining of the uterus. The zygote
  is attached to the lining of the uterus and
  becomes an embryo. The mother has missed her
  menstrual cycle, her breasts have enlarged, and

Case Study 2

• The fetus is 17-18 inches long and weighs 5-6
  pounds. The fetus continues gaining weight until

  as fat deposits continue to develop. Movement
  decreases as the fetus has less room to move
  around. The fetus acquires antibodies to fight
  disease from the mothers blood and moves into
  the pelvis, ready for birth. The mother feels
