29. Partner up!
You will be put into groups to complete the next assignments.

30. 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 up your diagnosis.

31. 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 she has to urinate frequently.
What month is this?
Month 1

34. Case Study #2
The fetus is inches long and weighs 5-6 pounds. The fetus continues gaining weight until the week before birth. The skin becomes smooth 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 mother’s blood and moves into the pelvis, ready for birth. The mother feels lightening as the fetus drops into the pelvis; breathing becomes easier. Other discomforts continue, and a total weight gain of pounds is typical. False labor pains called Braxton Hicks contractions may be experienced.
What month is this?
Month 9

35. Case Study #3
The embryo is ¼ inch long and has developed face, eyes, ears, and limbs. The bones have begun to form. The embryo changes to a fetus and remains a fetus until birth.

The fetus is about inches long, weighs about 2 ½-3 pounds as the month begins. The weight gain continues rapidly. The fetus may react to loud noises with a reflex jerking action. The fetus moves into a head-down position. The mother may show signs of discomfort from increased size. She might show signs of backache and fatigue along with leg cramps and shortness of breath. The fetal kicks may disturb the mother’s rest. At the beginning of the month, weight gain totals about pounds.

The mother’s abdomen has become large enough to let others know she is pregnant. Slight fetal movements are felt. Increased size has begun to affect her posture.
What month is this? 
Month 5

42. Fetal Development Growth & Weight Chart
Materials:
Construction paper
Ruler
Scale
Colored Pencils
PowerPoint Notes
Directions:
Use materials to create a size chart of the growth of the fetus each month
You should chart it on paper, month by month and beside each month measure the size.
Look for teachers example.
You will also use scales and classroom materials to determine the weight of the fetus each month.
Record your findings on the fetal growth chart construction paper.
