SC.912.L.16.13

The student will be able to describe the process of human development including major changes that occur in each trimester of pregnancy. 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.

In this lesson, students will examine the process of fertilization. First, students will make predictions regarding the structures of egg and sperm and how it will aid or impede the fertilization process. Students will also make predictions about why meiosis produces differences in the numbers of sperm and eggs made available. Next, students will use microscopes to examine prepared slides of sperm and eggs. They will sketch each and label structures, and answer follow up questions at various DOK levels. For a final activity, students will use a word bank to fill in a narrative paragraph describing the fertilization process.

The Making of a Marvel Part 1 is the first lesson of the reproductive unit (six lessons total). Students will begin with making cost analysis lists, as a class, of costs and benefits to asexual and sexual reproduction. The goal of this introductory exercise is to grab attention and illustrate that in sexual reproduction, the value of genetic diversity is well worth the cost. The second phase of the lesson begins with a brief discussion on the anatomy of both male and female reproductive systems. Together as a class we will then label diagrams of both systems. As a final activity in the lesson, students will receive cut out diagrams of both male and female systems. In this hands-on-manipulative students will match the corresponding structure and function labels given to them with the correct part of the diagram. This lesson follows the gradual release method of I do, we do, you do.

Type: Lesson Plan

Students will observe, explore, and create a story about the main structures of the female/male reproductive systems, describing how these systems interact during the process of fertilization to a create human being.

Type: Lesson Plan

In this lesson, students explore the development of the human fetus during pregnancy.

Type: Lesson Plan

Students learn about the male and female reproductive systems and the developmental changes of pregnancy. Students will create a timeline about the trimesters of pregnancy.

Type: Lesson Plan

Students will identify and/or describe the basic anatomy and physiology of the human reproductive system. Students will understand how the structures of the human reproductive system work together to create and deliver gametes for fertilization.

Type: Lesson Plan

Explore the genetic advantage of sexual reproduction, describe the basic anatomy and physiology of both the male and female human reproductive systems, describe the process of human development leading up to birth, and identify major changes associated with each trimester of pregnancy.

This informational text resource is intended to support reading in the content area. This is a fine synopsis of a previously reported (and highly technical) study that shows the thought process behind challenging an existing theory. The subject is human evolution and the biology of childbirth. It encompasses basic anthropology concepts such as walking upright, as well as the biology of energy needs in pregnancy. Long-held views (that narrow birth canals are required for bipedalism) are debunked by careful analysis of how women with varying hip widths actually walk—and the authors found no difference.

This informational text resource is intended to support reading in the content area. This article gives an overview of the human reproductive system, including the organs that are present in both sexes and the role that each gender plays in reproduction. It is organized in a manner that supports readers' comprehension of the subject and captures their attention.

Type: Text Resource

This informational text resource is intended to support reading in the content area. There are many stages of the development of living things. This article focuses on the development of a human being starting at fertilization. The author gives vivid descriptions of each step of the process, breaking these steps into two larger groups: early development and the fetal period.

This Khan Academy video describes what happens to a zygote as it becomes an embyro. It further explains what a stem cell is and discusses why there are questions concerning the use of stem cells.

This tutorial will help you to understand the function of the follicle. Each follicle is a single egg cell surrounded by several layers of follicle cells. An ovary consists of many follicles. The follicle cells protect and nourish the egg prior to its release into the oviducts during ovulation.
