Curated OER
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.
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
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 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.
Curated OER
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...
Curated OER
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
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...
LABScI
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
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
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...
