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.

Spotlight On Stem Cells
Students discover the differences in how stem cells develop and function depending on their source. They see how scientists are using stem cells - from a variety of sources - to study how they can be used to cure certain illnesses and...
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...

Biotechnological Issues and Bioethics
Culminate a bioethics unit with the implementation of a lesson that incorporates the Socratic method to encourage class feedback and participation. Pupils participate in a discussion on bioethics and morality, complete a writing seminar,...
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.

How To Make an Artificial Organ
High schoolers examine the advances made in technology with regard to prosthetics and replacement organs and limbs. They describe the anatomy and functions of different organs and create their own artificial organ. They defend and...
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...
Curated OER
Homology: Where Does The Evidence Lead
Students are introduced to the topic of homology. In groups, they read a case study and compare different drawings of early vertebrate emryos. They work together to answer discussion questions and label the various parts of each embryo.
Curated OER
The Cell Cycle and Cancer
Learners compare and contrast the cell cycle of frog eggs, normal cells, and cancer cells. They watch a video about early development of the frog embryo, generate a hypothesis in small groups, and listen to a teacher-led lecture. ...

Are Adult Pancreatic Beta Cells Formed by Self-duplication or Stem Cell Differentiation?
A case-study of Dr. Melton's experiment on pancreatic cells highlights this worksheet. Details of the study adorn the first three pages, complete with diagrams. Biology buffs then analyze the data and identify problems within the...

Understanding How Genes Are Inherited via Meiosis and Fertilization
Bring the excitement of genetics to scholars with a dynamic hands-on meiosis modeling experience. During the activity, biologists follow step-by-step procedures to build chromosomes, model independent assortment, learn about crossing...
Curated OER
A Hard Sell on Stem Cells?
Young scholars 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...
Curated OER
What Is Cloning?
Students differentiate between reproductive and therapeutic cloning and then use research, discussion, and writing in journals to examine their own personal opinions on these subjects.
Curated OER
Bioethics And Fetal Tissue Research
Pupils are introduced to the topic of fetal tissue implantation. In groups, they examine a case study and share information with the rest of the class. Then they do a reflective writing assignment to assess understanding of the ethical...
