Curated OER
Animal Reproduction and Development
Details of fertilization, cleavage, the placenta and fetal development are presented, along with important diagrams and illustrations. By using these slides, you and your students will generate discussion points, along with details...
Curated OER
Zebrafish Development
Students examine the early development of zebrafish as a model for embryo development in humans. They observe various stages of zebrafish reproduction from sperm and eggs to fertilized eggs and hatchlings.
Curated OER
investigating and Modeling Sea Urchin Fertilization and Development
Students begin by using clay to model fertilization and early development of sea urchins and chordates. They move on to mixing live sea urchin sperm and ova together to observe, diagram and record events occurring in fertilization and...

LP 6--8: Xenopus laevis (frog) Development for a 7th Grade Audience
Seventh graders view lab stations with Xenopus at different stages of development. They identify the life stage of the sample, as well as the previous and next stages. Students must explain their reason for selecting the specific stage.
Curated OER
Invertebrate Phyla
Students explore the invertebrate phyla. They discuss the characteristics of the invertebrate Phyla in the Kingdom Animal. Students classify organisms into Phyla based on their characteristics. They distinguish radial symmetry, bilateral...
Curated OER
Embryological Development Using Medaka Fish
High schoolers 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
Body Plans and Adaptations
In this body plans and adaptations activity, students will review the different types of symmetry found in organisms. Students will identify body parts as found on either the ventral or dorsal part of an animal. Then students will look...
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.
