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
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.

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...

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
Students 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...

Introduction to Human Anatomy & Physiology
If the only support you are in search of is lists of vocabulary terms, this presentation may fit the bill. Slides simply list terminology. These categories are included: hierarchy of structural organization, cell functions, cell...

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
Evidence of Evolution by Natural Selection
Walk your junior biologists through the evidence that supports evolution. The fossil record, anatomical record, and molecular record are explained and supported by colorful graphs and pictures. Extensive notes are provided for some of...
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.

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
Evidence for Evolution
In this evidence of evolution worksheet, students review notes given by referring to the Nelson Biology text, chapter 11/13. Students read the notes and the specified pages in the text.
Curated OER
Natural Selection
High schoolers 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...
Curated OER
Molecular Sequences & Primate Evolution: Amino Acids, Hemoglobins in Evolution
Students compare differences in amino acids in the beta hemoglobin from representative primates, complete a matrix of those differences, and from these data, construct and interpret cladograms as they reflect relationships and timing of...
Curated OER
The Pickle "Dill"emma
High schoolers study a problem in their local farming community regarding a pickle factory, and the class is asked to help determine if the pickle factory is the source of a seed germination problem.
Curated OER
A Feast for the Future
Students participate in an activity that uses a simulated meal of transgenic foods in order to initiate a discussion of the controversy concerning the use of transgenic food products.
