26 Two Sample Test Questions

27 1. Which illustrates the development of a fetus during the third trimester? A. Arms and legs develop B. Fingers and toes begin to develop C. Lightening occurs D. Nostrils, mouth, and eyelids form Answer=C

28 2. A pregnant woman is very restless and tired. She suffers from backache, shortness of breath, and leg cramps. Which stage of pregnancy is this? A. Conception B. First trimester C. Second trimester D.Third trimester Answer=D

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 mother has swelling of breasts and increased urination due to pressure on the bladder. She is not having nausea or morning sickness. What month is this? Month 2

36 Case Study #4 The fetus is 3 inches long and weighs one ounce. The fetus can suck its thumb, swallow, hiccup, and move around. The facial features become clearer. The mother’s abdomen continues to grow slowly. Most discomforts of early pregnancy, such as morning sickness, usually are gone. Appetite increases. What month is it? Month 4

37 Case Study #5 The fetus is about 8-10 inches long and weighs about 8-12 ounces. The mother senses fetal movement as strong kicks, thumps, and bumps---some may be visible. The mother gains as much as pounds during this month. What month is it? Month 6

38 Case Study #6 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. What month is this? Month 8

39 Case Study #7 The fetus is about one inch long. Nostrils, mouth, lips, teeth buds and eyelids form. Fingers and toes also develop. All the organs are present, although they are immature. The mother’s breasts become firm and full, and they may ache. Nausea, fatigue and frequent urination are still present. The abdomen becomes slightly larger. The uterus is about the size of an orange. The mother has gained 2-4 pounds. What month is this? Month 3

40 Case Study #8 The size of the fetus is inches long and weighs about 1½ -2 pounds as the month begins. The fetus experiences periods of rest and quiet. The mother’s increased size may affect her posture. What month is this? Month 7

41 Case Study #9 The fetus is about 6 ½-7 inches long and weighs about 4-5 ounces. Hair, eyelashes, and eyebrows appear and teeth continue to develop. The organs are maturing and the fetus is becoming more active. 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.

43 Fun Way to Remember Directions: –Use teacher’s example to create a fun way to remember the 9 months of pregnancy for Baby and Mother. Materials: –Index cards –Colored pencils –Teachers Mnemonic I will post on document camera

44 Brain Pop Directions: –Look on the board for Brain Pop username and password. –Go to website –Login –Click: Health Genetics, Growth & Development Fetal Development –Complete the following in this order: 1.Watch video 2.Quiz 3.Activities 4.Q&A 5.FYI –You will need to turn in evidence of Brain Pop use. One paper per group

45 Let’s see what you know! Directions: Close eyes and put heads down on desks. I will describe each month of pregnancy. You will hold up the # of fingers corresponding to the month of pregnancy that is described. Teacher will rotate around the room and touch student’s hand if incorrect. –If hand is touched you will know you need to try again! –If hand is not touched, leaved your fingers up until the next description is called out. Test may consists of 9-18 questions.

46 3.02 Fetal Development Test Review Directions: –Complete MiTiReLa 3.02 Learning Mode. –Record score after clicking daily progress. –Teacher will need to see and sign off on your MiTiReLa paper.
