Welcome to Year 12 Biology, 2011.
This course includes…
1. How to design and carry out an individual practical experiment at Level 2
2. How to research and write up interactions between humans and biology
3. Evolution through genetic variation and change
4. Ecology through studying ecosystems and their populations and communities
5. Diversity in animal structure and function
6. Diversity in plant structure and function
7. The basic units of life through cell structure and function
The focus of this course is to give you a high level, broad understanding of biology ideas and explanations. Assessments are secondary to this. However, you are expected to be working at an appropriate level.
Assessment and reassessment
All assessment is during the school year and is at NCEA Level 2.
There will be four internal assessments during the year. Table 1 has more detailed information on the topics we will cover and assessments.
There will be no reassessment opportunities and only one resubmission opportunity for any internal assessments. There will be clear signposts to your Whanau teacher, Dean and parents if you are not working at an appropriate level.
You are expected to be working at a level considered appropriate by the teacher and that has been negotiated with your Dean and parents.
The final examination in November assesses the external standards.
Rules and Regulations
There are some very specific rules about assessments. Please refer to your NCEA handout, particularly about the ownership of work and plagiarism.
Stationary
Year 12 Biology Student Workbook – to be purchased through school.
A 20+ page clearfile and refill to use for laboratory work and research.
Field Trips
There is one field trip to Tautuku Outdoor Education Centre in the Catlins from Wednesday 23th June to Friday 25th June (Term 2). This trip is essential for collecting data for one of the internal achievement standards which will be completed during the trip. You must make sure you can attend. Cost is approximately $90 and more information will be handed out closer to the time. Anyone unable to attend must inform the teacher by the end of Term 1 or they will be expected to pay the full amount.
Homework
Homework will be assigned when appropriate and you will be expected to complete it on time. It is also expected that you revise work covered during class on a daily basis – this is essential for getting on top of content for the external assessments.
Tutorials
Ask for them when you want them.
Laboratory work
Some practical work is assessed. All practical work is to be attempted. Be safe in the lab: follow and learn all the rules set down. In case of an emergency, listen to your teacher: they know what they are doing.

Explanatory Notes
1. This achievement standard is derived from Biology in the New Zealand Curriculum, Learning Media, Ministry of Education, 1994, p. 38, ‘Developing Scientific Investigative Skills and Attitudes in Biology’.
2. Procedures outlined in Safety and Science: a Guidance Manual for New Zealand Schools, Learning Media, Ministry of Education, 2000, should be followed. Investigations should comply with the Animal Welfare Act 1999, as outlined in Caring for Animals: a Guide for Teachers, Early Childhood Educators, and Students, Learning Media, Ministry of Education, 1999.
3. Investigations will be based on situations arising from content at level 7 of Biology in the New Zealand Curriculum, Learning Media, Ministry of Education, 1994, pp. 20-26.
4. An investigation is an activity covering the complete process: to plan, carry out, process and interpret data, and report on the investigation. It will involve students in the collection of primary data. It is expected that students will have opportunity to make changes to their initial method as they work through the investigation.
5. The nature of the investigation could be the manipulation of variables (fair test) or the investigation of a pattern or relationship.
6. With supervision means the teacher gives students guidelines for the investigation such as the context for the investigation, instructions giving the requirements for a quality investigation, and broad experimental conditions such as the availability of equipment or chemicals. It may also involve discussion with individual students in order to clarify their ideas. Students then develop and complete the investigation from the initial guidelines given by the teacher.
7. A practical biological investigation will involve
• a statement of the purpose – this may be an aim, testable question, prediction, or hypothesis based on a scientific idea
• a method that describes:
– for a fair test: the independent variable and its range, the measurement of the dependent variable and the control of some other key variables
– or pattern seeking: the data that will be collected, range of data/samples, and consideration of some other key factors
• collecting, recording and processing data relevant to the purpose
• interpreting and reporting on the findings with a conclusion reached based on the processed data in relation to the purpose of the investigation.
8. A quality practical biological investigation enables a valid conclusion to be reached. This would normally involve
• a statement of the purpose – this may be an aim, testable question, prediction or hypothesis based on a scientific idea
• a method that describes:
– for a fair test: a valid range for the independent variable, the valid measurement of the dependent variable and the control of other variables, with consideration of factors such as sampling bias and sources of errors
– for pattern seeking: a valid collection of data with consideration of factors such as sampling bias and sources of errors.
• collecting, recording and processing data to enable a trend or pattern (or absence) to be determined
• interpreting and reporting on the findings with a valid conclusion reached based on the processed data in relation to the purpose of the investigation
• a discussion of the biological ideas relating to the investigation.
9. Evaluate means to justify the conclusion in terms of the method used. This will involve, where relevant, consideration of the:
• reliability of the data
• validity of the method.

Only one format is required to show an interrelationship or pattern.
8. Biology of the organism refers to any adaptation of an organism that relates to the interrelationship or pattern being investigated.
9. Terms:
• Describe requires the student to recognise, name, draw, give characteristics of, or an account of.
• Explain requires the student to provide a reason as to how or why something occurs.
