Human Cloning: Is it Biological Plagiarism?
Is cloning good or harmful? Help your class understand the risks and benefits as they read, research, and discuss human cloning. Individuals form teams, research information, and present to the class before concluding with an in-depth...

The Way We Were: Embryological Development and Disease
Young scholars use microscopes to study live fish embryos and animated diagrams of cell division on the Internet. They see that scientists rely on technology to enhance the gathering and manipulation of data. They create web pages on...
Curated OER
Variety Is the Spice of Cellular Life
Do you need to review animal cell structure? Investigate the ways in which different types of cells interact in a common human reflex. Your students can explore the functions of stem cells, consider various illnesses and assess stem...
Curated OER
Human Embryology
Ninth graders are introduced to the concept of human embryology. Individually, they complete an exercise in which they determine which trait they got from which family member. In groups, they identify and label the reproductive organs...

LP 6--8: Xenopus laevis (frog) Development for a 7th Grade Audience
Seventh graders view lab stations with Xenopus at different stages of development. They identify the life stage of the sample, as well as the previous and next stages. Students must explain their reason for selecting the specific stage.
Curated OER
Zebrafish Development
Middle schoolers examine the early development of zebrafish as a model for embryo development in humans. They observe various stages of zebrafish reproduction from sperm and eggs to fertilized eggs and hatchlings.
Curated OER
Heredity, Genetics, Traits
Eighth graders study how an embryo develops into a fetus by undergoing many physical changes which they observe on a poster. They examine the metamorphosis of fruit flies as they develop through a series of changes. They record the...
Curated OER
Embryo Development
Students observe the development of a chicken embryo. In this biology lesson, students compare and contrast the development of human and chick embryo. They make a chart and explain their findings to the class.
Curated OER
The Effects of "Recreational" Drugs on the Development of Chick Embryos as a Model for Human Embryogenesis
Young scholars conduct experiments on fertilized chicken embryos to determine the possible developmental effects that various recreational drugs (caffeine, alcohol, nicotine, and aspirin) might have on them.
Curated OER
Assisted Reproduction
Students are actively involved in presenting some of the issues in implanting previously frozen embryos through a cooperative learning lesson. This lesson helps students to develop decision-making skills through discussing various types...

Comparative Embryology Using Japanese Medaka Fish
Students conduct an experiment to control the breeding of Japanese Medaka fish. They collect the fertilized eggs and view and record the fish's embryological development daily to compare the stages to human development.
Curated OER
Zebrafish as a Model for Muscle Development
Students explore the steps of protein synthesis in zebrafish. They view video clips to identify the parts of a zebrafish and observe them as they sequence the developmental stages. In groups they identify the muscles and how proteins are...
Curated OER
Comparative Embryology
High schoolers compare and contrast the embryonic development of human, chicken and fish embryos. They create a detailed outline of similarities and differences among the three embryos at various stages of development.
Curated OER
Zebra, Zebra Where Are Your Stripes?
Students observe the embryological development in the zebrafish. Developmental hierarchy from three germ layers is studied in depth. Research is validated on the body plan of the embryo.
Curated OER
Natural Selection
Students estimate how many different species of organisms inhabit the Earth. In groups, they match the pictures of embryos at the different stages of development. They compare and contrast animals from the sky, land, and water and...

The Effects of Alcohol and other Teratogens: A model using Zebrafish
Students investigate the interference of various drugs on an embryo through experimentation. This is an open-ended lab to allow students to see effects of various chemicals humans choose to put in their bodies and create questions they...
Curated OER
The Energy of Life in Zebrafish
Students study the stages of development of an unknown organism. In this zebrafish lesson, students examine and collect data as they use microscopes to view a zebrafish embryo.
Curated OER
A Hard Sell on Stem Cells?
Students examine their prior knowledge of cell regeneration and therapeutic use of stem cells. After reading an article, they discover new techniques for deriving embryonic stem cells. In groups, they research on the different types of...
