Do You See What I See? Lesson Overview

The student will be able to describe the process of human development including major changes that occur in each trimester of pregnancy.In this activity, students will become scientists and explore the major changes that occur during embryo development. First, students will work in groups and correctly match the fetal development picture cards with the appropriate description. Next, students compare and share their findings with other groups and record this data. Finally, students will act as physicians as they investigate a medical case study of a pregnant woman and determine what trimester she is in by analyzing ultrasound reports detailing certain makers of the stages of development. Students will use a claim, evidence, rationale style activity using the ultrasound pictures and learned content to support their answers. The lesson culminates with students sharing their findings through a gallery walk.

Engage 5 min 1.3, 3.1, 5.3 Internet & Video 2 Students watch a video and make observations on the developmental changes that occur during pregnancy.
Explore 40 min 3.3, 3.5, 3.7, 5.3 none 3 Students will match pictures of a growing fetus with the appropriate descriptions. Next, students match picture and information cards to learn the stages of fetal development.
Explain 10 min 6.1, 6.2 none 3 Students will answer questions about their learning and understanding from the explore activity.
Expand 40 min 7.2, 7.3 none 2 Students will act as physicians and examine a medical case study of a pregnant woman. In the investigation students will need to find out how far along the patient is in her pregnancy by analyzing post ultrasound reports indicating certain markers of the stages of development. Based on the given evidence, students will diagnose which trimester the patient is in, support their claim with evidence from their previous work, and the rationale for their evidence. Students will share their CER with other students through a gallery walk.
Evaluate 5 min none 1 There are formal and informal assessments available for this activity.

Level of Student Engagement
1     Low     Listen to lecture, observe the teacher, individual reading, teacher demonstration, teacher-centered instruction
2     Medium     Raise questions, lecture with discussion, record data, make predictions, technology interaction with assistance
3     High     Hands-on activity or inquiry; critique others, draw conclusions, make connections, problem-solve, student-centered
