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...
Curated OER
Chick Embryology
Students investigate techniques that can be used to observe the development of the chick embryo. They explore the environment in which the chick develops and how it can be manipulated.
Curated OER
Elegant Embryology
Students observe embryogenesis in action through early stages of development of eggs. They observe cultures with dissecting and compound microscopes. They draw their egg, record any details and observe for changes. They compare their...
Curated OER
Comparative Embryology
Students 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
Embryology as Evidence of Evolution
Students observe the two major developmental pathways (protostome and deuterostome). They analyze data regarding differences in nucleotide sequences and construct a phylogenetic tree. They observe the similar evolutionary history shared...
Curated OER
The Embryology Review Game
Students create a game that may be used to review and reinforce embryological terminology and concepts. They create a game board and question cards while promoting cooperative learning.
Curated OER
Embryological Development Using Medaka Fish
Students analyze and record major events that occur in the development of Medaka fish eggs from fertilization to hatching. In small group, students describe the processes involved, creating a timeline of the major events in the...
Curated OER
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
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
Evidence of Change
Pupils identify evidence of change in species using fossils, anatomical similarities, and embryology. They identify homologous structures and arrange the steps of fossil formation. Students complete a group of selection of organisms by...
Curated OER
Stem Cell Differentiation Game Questions
Thirty-five multiple-choice questions are spread out into boxes bordered with dotted lines so that they can be cut out to become game cards. Playing a game to review concepts is an effective way to learn, even if you are in college. Give...
Curated OER
Comparative Embryological Study of
Students complete two labs. They observe the fertilization and development of sea urchin and zebrafish embryos. They examine the similarities and differences in the development of an invertebrate vs. a vertebrate animal.

A Study of the Effects of Ethanol and Heavy Metal Chemicals on the Development of the Zebrafish Embryo
Students are exposed to the dangers of alcohol abuse through the study and experimentation of alcohol on zebrafish embryos. This exercise can be used to demonstrate the effects of ethanol, cadmium, and lead on embryological development.
Cold Spring Harbor Laboratory
Master Genes Control Basic Body Plans
Have you ever been so tired you missed a major announcement? Eric Wieschaus woke to a call explaining he won the Nobel Prize, but he thought it was just a dream until Christiane Nusslein-Volhard, a co-winner, explained it to him later...
Curated OER
Apoptosis: Programmed Cell Death During Development
Students model the plasticity of neural pathways for memory in the brain. They simulate the cell activity according to dots on cards that they are given. They complete various simulations of different cell combinations.
Curated OER
Inside the Egg, Hatching Chickens
Young scholars explore how an egg becomes fertilized. In this biology lesson, students "candle" a variety of eggs in order to determine which ones have been fertilized and which ones haven't. Student use paper plates to create a graphic...
Curated OER
Sea Urchin Embryology
Students explore the process of evolution. They examine examples of how homeotic genes may work and obtain gametes. Using a microscope, students observe the fertilization of sea urchins. They video tape the process and write a...
Curated OER
The Effects of "Recreational" Drugs on the Development of Chick Embryos as a Model for Human Embryogenesis
Students 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
AN EMBRYOLOGY PLACE MAT
High schoolers create a place mat to attain the following objectives: determine the important ideas, concepts, and definitions relating to a list of embryological terms. Match the terms with their definitions and create short quizzes for...

Embryology Word Search Puzzle
In this biology instructional activity, students look for the words that are part of the word search puzzle that is focused around the theme of the sheet embryology.
Curated OER
SEXUAL LIFE CYCLE DEVELOPMENT USING MONOCYSTIS
Students perform a lab to becoe familar with scientific concepts. The skill of inquiry is essential and this lesson furthers its development. The intelligence of kinesthetics is used as learners perform the many aspects of this lab...
Curated OER
Introduction to Kingdom Animalia
Embryology and symmetry of animals is presented in this group of slides. Because it covers embryonic germ layer, protostome, and deuterostome development, it is most appropriate for your advanced biology learners or college students. Use...
Curated OER
Zebra, Zebra Where Are Your Stripes?
Learners 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...
