Success!! 100% fertilization

Today at day 6 the embryos are 'candled'. We find 100% fertilization, all eggs are developing nicely.

We can see when the egg is placed near an overhead projector that light passes through the transparent egg shell but we see a dark shadow where the network of veins are developing and the even darker still outline of the duck embryo.

We can keep an eye on the development by using this method which is non invasive. The following link has a gallery of images to show duck development visible through candling. Click here. 
We will be able to observe any eggs that die during development and remove these from the incubator if required.

Hatching success rates in incubating duck eggs is rarely 100%, this is often due to fluctuating humidity (water) levels, not turned frequently enough or the duck not breaking through the membrane/shell if the membrane dries out. We can predict perhaps 6-8 of the 12 eggs to complete development and pip successfully.

One of our developing ducks can be seen in this photo

Are humans still evolving????

Hi Students (and Caregivers)

We hope you are enjoying your holidays and are having a restful break. 

We also hope you are revising for the examinations and if you are interested in coming to a study class check out the following timetable.

 

These are open to all students regardless of your subject teacher and you are welcome to invite other HVHS students who might not have received this email. 

Classes will take place in B11/B12 (or check door for any room change on the day). 

It would be great if you could please reply by email to let us know which class/s you may attend so we have an idea of numbers.

The structure of these tutorials will be students working in small groups on model question/answers, completing workbook activities, plus come with any problems/questions you have on specific topics

Regards

Mr Edwards
