Year 12 Biology 2014

Dear Students

Welcome to all new year 12 Biology students. This year is going to be great. We have four of the best teachers at Hutt Valley High School looking after you, and of course Biology would have to be the most interesting subject ever studied at school.

We are beginning the year with an internal assessment investigating a pattern in an ecological community. Our focus is going to be on the effect of introduced mammals on a native species of your choice. The other topic we will begin in term one is the life processes at the cellular level which is an external achievement standard.

Biology Revision Classes

All Y12 Bio students are welcome to attend these revision classes taking place in B11. These have been scheduled to fit around 12 Chemistry classes so that there is no clash with time and less trips into HVHS. 

If you are finding elements of your externals difficult we really encourage you to attend and bring lots of questions!!

Thursday 7 November          0900-1100       Topic = Cell Biology

Wednesday 13 November    1200-1400       Topic = Gene Expression

Thursday 14 November        0900-1100       Topic = Genetics and Variation   

Chemistry is scheduled spell 3/4 on Thursday 7 & 14 and Spell 5 on Tue. 

A reminder that your BIOLOGY EXAM is scheduled on the 22nd November at 0930.

Last 12 Biology class for 2013

Team Excellence?

12 Biology revision

Dear Students

I hope your Biology revision is well underway and you are making good use of the long weekend. In class last week I mentioned two very good web pages that could help your preparation. They were No Brain too Small and Pass Biology. 

Regards

Mr Edwards

Dear Students

This Saturday 19 October there will be a Biology revision class in room B 12 from 1 pm to 3 pm.

Students from any Biology class are welcome to attend.

Collaborative activity - Genetic Drift NZ Examples

Hi 12BIO students of Miss Meehan
Please find the link below to contribute your research idea (1 x Founder, 1 x Bottleneck) to the NZ examples list.
Click here and edit the table by adding your contribution. If table is fill, create a new row by clicking at the end.

What are linked genes?

Are you stuck on what is genetic linkage?

Normally when we talk about dihybrid crosses we are looking at two different traits where the genes responsible are on different chromosomes (i.e trait A on Chromosome 2 and trait B on Chromosome 7), but sometimes the two traits were are looking at are on the SAME chromosome. If this is the case then we will see a different inheritance pattern in the offspring - there will be less variation as the genes are inherited together as a pair.

The following page has some walk through videos that show meiosis of linked genes with and without crossing over. Click here.  (Sex linked traits are also discussed here, this may be interesting as an extension)

Population genetics simulation program

Use this simulation to see the effect of genetic drift. Try changing the features of the population and view the effect on the allele frequency.

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
