biol+2+assessment

Info about various assessment tasks can be found below.


 * Ecological issue (Friday 7th, 12th and 14th November) **

You have a double and a triple to work on this and be ready for the Ecoconference on Friday 14th November.

Link to the ecological isse page is below. biol 2 ecological issue


 * Homeostasis test (Monday 11th August) **

You will need to be familiar with all thework covered over the last two weeks.
 * Stimulus-response model
 * Negative feedback
 * Nervous and endocrine systems
 * Glucose regulation
 * Thermoregulation
 * Water balance

**Zoo excursion task** information and group lists

**Area of study 2 biology skills test (Wednesday 17th September)**

While you have been given the content that is important, this assessment is more about the biological skills associated with the content.

For example
 * measuring distribution and abundance
 * quadrat sampling and transect lines
 * creating food chains and linking into a food web
 * understanding the implications of changes to a food web
 * describing and explaining the various interactions between organisms in a given ecosystem

The key is that you will be given information in a variety of contexts that you may not have seen before and therefore have to apply your knowledge and understanding. You will not have to worry about plant hormones, reproductive strategies or animal behaviours for this task as they are part of area of study one. But of course they will be examinable later on!

**Media analysis (due beginning of lesson on Friday 24th October)**

You have been given the media articles and question handout. Spread the workload out, don't try and do it all in one go. If you lose any of the articles or handout, use the links below. You will have the option of working on this task in the lesson on Wednesday 22nd October. [|biol2 media analysis AT 2008.doc]

**Field trip report (due Wednesday 29th October)**

You have Wednesday 22nd October double lesson to work on analysing the results as well as part of the Friday 24th October double. A copy of the report guidelines is below. [|biol 2 scientific report on field study.ppt]

You can access all the photos on the studentdrive in the 11 biol folder. You can also post any questions and queries using link below. biol 2 field study report

**Area of study 2 test (Wednesday 5th November)**

You will need to be familiar with all the content covered as part of area of study 2. This section relates to ecosystems and all the associated ideas.

For example
 * characteristics of an ecosystem (abiotic and biotic factors)
 * measuring distribution and abundance in an ecosystem
 * creating food chains and linking into a food web
 * understanding the implications of changes to a food web
 * describing and explaining the various interactions between organisms in a given ecosystem (including feeding and symbiotic relationships)
 * human impact including introduced species, chemical control (and therefore also bioaccumulation)
 * population dynamics of ecosystems
 * movement of energy and matter in an ecosystem (including cycling of carbon and nitrogen)
 * ecological succession
