AS 91158 (2.6): Investigate a pattern in an ecological community, with supervision
AS 91158 (2.6): Investigate a pattern in an ecological community, with supervision
In this unit we will investigate how the biology of a species relates to the pattern of their distribution within their environment in which they live, with a focus on the intertidal rocky shore.
The biology of a species involves looking at the structural, behavioural, and physiological adaptations of organisms and how they are related to the physical environmental conditions as well as the inter-relationships of organisms within and between species that they navigate on a daily basis (e.g. competition, predation, or mutualism).
We are looking forward to a field trip to Motukiekie in early March, a local rocky shore, to conduct our own field observation to provide data for our assessment report.
AS 91156 (2.4): Demonstrate understanding of life processes at the cellular level
AS 91156 (2.4): Demonstrate understanding of life processes at the cellular level
In this unit we will investigate how life functions by understanding processes at the cellular level which will include: photosynthesis, respiration, cell division, DNA replication, and mitosis as part of the cell cycle. To understand these processes we will learn about biological models and ideas relating to: plant and animal cell structure and function, movement of materials (including diffusion, osmosis, active transport) and enzyme activity.
AS 91153 (2.1): Carry out a practical investigation in a biology context, with supervision
AS 91153 (2.1): Carry out a practical investigation in a biology context, with supervision
This unit requires us to produce a biological report on the relationship between the temperature that the pectinase enzyme works at and the amount of apple juice that can be produced from apple sauce as a result of this enzymes action.
As part of the assessment you are required to:
Carry out the practical investigation in groups of up to 4 to collect data
Process and interpret your data and report on the investigation individually
Look for trends and interpret your findings in terms of enzyme action in different temperatures.
Compare your results with the whole class and findings from books/online and other class graphs to help you with your thinking about the success or otherwise of your findings.
AS 91157 (2.5): Genetic Variation and Change
AS 91157 (2.5): Genetic Variation and Change
This achievement standard involves defining and using annotated diagrams or models
to describe and provide an account of, genetic variation and change. Genetic variation and change involves exploring the following concepts:
Sources of variation within a gene pool
Factors that cause changes to the allele frequency in a gene pool
Mutations as a source of new alleles
Independent assortment, segregation and crossing over during meiosis
Monohybrid inheritance to show the effect of co-dominance and incomplete dominance
Lethal and multiple alleles
Dihybrid inheritance with complete dominance
The effect of crossing over and linked genes on dihybrid inheritance
Natural selection
Migration
Genetic drift
AS 91155 (2.3): Demonstrate understanding of adaptations of plants and animals to their way of life
AS 91155 (2.3): Demonstrate understanding of adaptations of plants and animals to their way of life
This internally assessed activity requires you to work individually to develop a portfolio of information which you can use to produce a written report OR slideshow on the adaptations relating to the digestive system in mammals, fish and molluscs - or three different animal groups of your choice.
The portfolio should also include information on how at least two adaptations per animal allow these animals to carry out digestion effectively and occupy the ecological niches that they do.
Complete a written report comparing and contrasting adaptations relating to digestion within your chosen three animal groups to show how or why these adaptations allow each group to survive in their habitat.
Your report should:
Scientifically name the three animals and their taxonomic groups you have studied and provide a brief description of their ecological niches e.g. physical habitat, as well as their relationships with other organisms.
Describe the structural, behavioural and/or physiological adaptations that enable each animal to carry out digestion. At least two per animal group.
Explain how or why these adaptations enable each animal group to successfully carry out digestion in order to survive in its habitat. You should provide examples to support your explanations.
Discuss how these adaptations for digestion are connected in each animal. Your discussion should include examples linking several biological ideas to show how the adaptations:
enhance the effectiveness of digestion in each animal
have limitations and advantages of named features or processes within each animal.
You may use annotated diagrams to support your answer.
