Creepy phagocytosis!

Check out the Neutrophil (a special white blood cell) gobbling up the bacterial cell in this short video. this happens as part of the immune response when cell membranes detect 'foreign' cells.

The second clip shows two PROTISTS (we will look at some of these under microscopes next week). The Amoeba is phagocytosing the Paramecium.

Amazing cells!! (great interactive resources)

Check out the following link to look at comparision of size between different cells, cell structures, bacteria, virus and molecules. This page (click here) also has a huge number of videos that will be useful to watch along side your BIOZONE activities.

View A TOUR OF THE CELL and then view INSIDE THE CELL - click on the organelles of animal and plant cells to find out more about what they do.

Ecology Investigation

Have you chosen which native species you are going to research for your assessment?  By now you have covered the theory in class and you should be busy collecting articles and information so you have all the material you will need to write your reports.
One good way to get started could be to read the Wikipedia entry for your species. At the foot of the Wikipedia entry there is a list of references they have quoted. These references are a great starting point for your research. Please ask your teachers if you have any problems.

Reproductive strategies

In this clip Mr Anderson talks about two different reproductive strategies, R and K. After watching this clip, you should consider what does R stand for? What does K stand for? What does it mean by a continium? Think about our native species, what strategy do they follow in general? Compare with Introduced species? What impact will this have on populations of our native species?

Hutt Valley Science Student Day

YEAR 12 and 13 SCIENCE STUDENTS: THE HUTT VALLEY SCIENCE STUDENT DAY:

Friday 1 March Spells 1-4.

We have 7 invitations to the GNS Science Day. It’s a hands-on program of activities that include making your own icecream with liquid nitrogen, splitting the atom with ion guns and carbon policing the air. So if you are thinking you might study Science at tertiary level and could be keen to obtain future employment locally –this would be ideal for you. Sign up on the Science Department Noticeboard.

What is an ecological niche?

The following video clip from 'the virtual school' gives a good overview of what an ecological niche is and how we describe them. Click here to watch clip

2013 has begun

Dear Students

Welcome to level two Biology for 2013. Please make use of this blog during the year to follow up our in-class activities. In particular I would urge you to view the internet links for videos and online learning.
