AS90718+Biological+Techniques

This is an internal assessment worth 3 credits. The assessment will be issued on May the 2nd. View the Achievement Standard below,

AS90715

= ﻿Internal Guidance .... 25th May comment from Ms Altena = Your assignments are due Friday, be prepared and ready to hand in on time. Remember if you are late you will get an Not Acheived From the selection of reports I have read I have some general comments for you all.

Many of you are DESCRIBING the techniques well, however there is not the depth in your EXPLAINATIONS - this means to say WHY a particular step or substance or temperature etc is required/done. The types of works teachers look for as indicators of an explaination are BECAUSE, THEREFORE, AND SO, THIS MEANS, THIS OCCURS BECAUSE ...

Refer to the marking guide in your assessment for the general marking criteria﻿. Click on the AS90715 link above to reread the actual NCEA standard.

For excellence the standard states you need to evaluate :- //Discuss// requires the student to show understanding by **linking biological ideas**. It may involve students in justifying, relating, evaluating, comparing and contrasting, and analysing.

So consider **what aspect(s)** of your report you can do this ie it might be in the assessing the human need ... evaluate the application or justify its use or the use of one technique over another.


 * This is a relevant and interesting topic, I hope you remember to be facinated by the complexity of what you are investigating. Enjoy :) **

In class we will look at both the Techniques and Applications
==Then you will do your own research on two Applications and in doing so explain two techniques involved in each application. To be clear you will be discussing four techniques in total ... two for each appliciation.==

Class work Wednesday 11th May ... click here
Follow the links, complete the exercises and reading in Biozone (p 283 - 334) - note we will not cover all techniques and applications in class, this will not be necessary for this assessment. You will be amazed and inspired and may wish to learn about all the techniques.

Also the ESA guide textbook contains details of Techniques in Chapter 27 p 321 and the Applications are in Chapter 28 p335

There are many interactive websites to access to see the techniques. Follow the links above and explore :)

Hi there, Gavril here.

As some of you know, I went to Hot Water Beach to collect some samples to be tested. However, that activity was cancelled but instead we went to the labs at Mercury Bay Area School and extracted and amplifed the DNA available in the sand sample collected on Friday by the scientists from Massey University and students from Mercury Bay Area School. The process used was DNA extraction and PCR(polymerase chain reaction).

I made a log on what we did and notes on lectures from scientists.
