This page introduces K12 teaching resources related to embryology and development. The current page is designed to help teachers find useful curated online resources for use in biology classes related to embryology and development. The content and links on this current page are under ongoing development, I am happy to receive feedback and requests for design of specific K12 content and exercises for your classes.
The section entitled Additional Useful Resources links directly to resources and currently there is no content designed for K12 student use, but content and resources on these pages may be useful in designing your own specific content around these topics.
Note that content on K12 pages has been simplified in both terminology and descriptions from that found on other embryology pages designed for university level students. That does not mean that other embryology pages are not useful for students, but may be to difficult to place in context given the advanced terminology and descriptions used on non-K12 pages.
Note that clicking the "Expand" text on pages will open collapsible tables with more information or resources.
|Please note content on this site has been derived from a number of sources and under a range of different copyright conditions. I am happy for educational reuse in the classroom without republication. I specifically do not allow republication of content on the internet. This is to prevent misuse of content out of context and also to prevent multiple search results for the same content. In general, opening an image will show the specific copyright restrictions associated with the image.

Student exercise sheets have been designed to be printed and used in the classroom.
Below are a list of the current K12 designed resources.

|This page has been designed as an introduction to Comparative Embryology. The page has 4 student exercises contained within collapsible tables. These exercises have worksheets that can be printed out to be completed by students. Also look at the series of student designed projects on animal development.
Comparative Brain Anatomy
|This page was designed originally as a presentation for brain awareness week. Students should understand that the description of early brain development is the same for most species. A more specific page on K12 Comparative Brain Anatomy is under development.
Additional Useful Resources
The following pages are not designed for K12 students but may provide background information and resources for teachers in other Biology areas.
|The movies page has many different animations showing developmental processes. Some of these movies are simplified cartoons, while others are derived from developmental research articles.
The moves can be:
This is the first MRI recording of childbirth.
These pages are designed for university level students but also contain images and movies that can be used with students.
The page link opens a movie page with additional descriptions about what is being shown in the movie.
|This movie shows chromosomes being segregated during mitosis, the last image is a normal microscopic view of the 2 daughter cells following cell division. Chromosomes have been labelled (white) and align at metaphase, then separate into the two daughter cells. Note the chromosomes unfold at the end of mitosis.
Exercise - Allow the students to see the unlabelled movie and then identify specific stages of mitosis by time. The labelled movie can be shown after the student have attempted the exercise.
|This movie shows how in the oocyte (egg) during meiosis 1 excess DNA is segregated into a specialised structure, the polar body. The polar body contains DNA in an exclusion body that does not contribute to the embryo. DNA is labelled blue and the same oocyte is shown in both bright field (left) and fluorescence (right). Note the remaining oocyte chromosomes arrest at metaphase 2.
This generally available cartoon image shows the major structures in DNA compaction from duplex to chromosome. Note that this process of compaction occurs only during preparation for cell division and that cells carrying out their normal function have uncompacted DNA to allow gene transcription.
|This cartoon shows the general structure of the nucleus when the cell is transcriptionally active and not dividing. Chromosomes are unravelled and spread throughout the nucleus in "chromosome territories".|
|There are also a set of cartoon diagrams illustrating genetic mechanisms of inheritance. There is also a downloadable student worksheet exercise on inheritance patterns (see below).
Current Reproductive Technologies
Louise Brown, the first IVF baby as an adult.
|The general public more commonly recognise the term In Vitro Fertilisation (IVF).
Note the Nobel Prize in Physiology or Medicine 2010 was awarded to Robert G. Edwards "for the development of in vitro fertilization" who battled societal and establishment resistance to his development of the in vitro fertilization procedure, which has so far led to the birth of around 4 million people. (More? Assisted Reproductive Technology | Nobel Prize 2010) 10 April 2013 - Sir Robert Edwards has died aged 87. BBC News
Exercise - Students should identify the many different ways in which pregnancy can be now be achieved using ART.
|Statistical data on assisted reproductive technology is released regularly in this publication. Student can download the full report and there is an overview executive summary available.|
Anatomy and function of the Human Ear
|This is a university lecture on the immune system, but also contains easily understood simplified cartoons and electron micrographs of B and T cells.|
