Comparative Embryology
Young scholars 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.

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
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...

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
Evolutionary Relationships Based Upon Comparative Genetics
Young scholars investigate the protein cytochrome c in an attempt to use its genetic chemistry to study possible evolutionary relationships between organisms. The lesson integrates technology with the use computers to perform DNA analysis.
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.

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
Comparative Embryological Study of
Learners 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.

Adaptation and Evolution
Um may be the atomic symbol for confusion, but it won't be needed in this lesson. Scholars rotate through seven stations completing experiments, hands-on activities, writing exercises, and analysis. Stations include material on...

Using Living Organisms to Explain Evolution
Students investigate evolution in its most fundamental form: the observation of living organisms. By comparing variations that exist among living animals, students formulate their own hypotheses and conclusions about the evolution 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.
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...

Molecular Sequences & Primate Evolution: Amino Acids, Hemoglobins in Evolution
Young scholars 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...
Curated OER
THE EMBRYO GAME
Students develop a game similar to BINGO. They compare the reproduction and embryo development of different organisms while initiating group and cooperative learning. They constuct cards from vocabulary words.
Curated OER
Gene Regulation Mechanisms
Students explore genetics. They discuss how chromosomes and/or genes are regulated during the life of an organism. In a lab setting, students compare and contrast the genomic regulation of prokaryotic and eukaryotic cells using...

Taxonomy: Who is in My family?
Find similarities in seemingly unlike organisms. The second instructional activity in a series of 12 builds the concept of a taxonomy and explores the use of a dichotomous key. Learners begin in part one by attempting to group a set of...
Curated OER
Who is the Sea Otter Related to?
Students examine the genetic relationships of different organisms. In groups, they discover the importance of genes and how different amino acids show various evolutionary relationships. They use an online database to continue their...

Inside the Egg, Hatching Chickens
Students conduct an egg candling activity to show the life inside a fertile egg. Students discuss the needs the egg has of the hen, as well as similarities and differences between plants and animals. Students complete a life cycle wheel...
Curated OER
Stem Cell Bioethics
Students study the steps of embryonic development. They distinguish between the advantages/disadvantages of embryonic stem cells vs. adult stem cells and discuss the ethical implications of stem cell research.
Curated OER
Gene Regulation Mechanisms
Learners explore the control of expression of DNA into proteins which is divided into two main categories: transcriptional and post-transcriptional. They construct examples of the control mechanisms and discuss disease processes that...

How Fragile Is an Egg?
Young scholars design a "container" for his/her egg to determine whether the egg remain intact when dropped from a predetermined height.

Development of I.Q. and the Degree of Relatedness
Studnets, in groups, analyze data regarding genetic and nongenetic relationships of I.Q. They make observations and discuss correlations from a diagram. Cooperative learning teams discuss a given set of questions and present information...

Alex: Why Comparative Embryology Matters in the Real World
In this lesson, students compare similarities in the embryos of different organisms to look for features that would indicate common ancestry. They will then investigate how understanding this aspect of evolution has real-world...
