VCE Biology students will learn biological concepts and undertake field research techniques to enable them to fulfil the assessment requirements for school-assessed coursework (SACs) in scientific investigation.
The physiology and behaviour of common intertidal species within Ricketts Point Marine Sanctuary will be explored. Applying an ecological perspective, students will undertake an area study to observe and determine how species adaptations, relationships and interactions with abiotic factors in the environment influence their survival in this challenging habitat. Insight provided into the function of physiological systems (e.g. homeostasis and osmoregulation) within an aquatic environment will reinforce students’ classroom learning.
Students will have an opportunity to develop their fieldwork skills including the use of quadrat surveys, species identification and classification techniques (e.g. the dichotomous key), field observation and data recording, as they investigate the distribution and abundance of intertidal reef species. Through discussion, students will be enabled to formulate hypotheses and interpret data results to develop conclusions for compilation into scientific reporting.
This program delivers:
– Overview of Victoria’s Marine National Parks systems and the role they play in the protection of Victoria’s marine biodiversity.
– Developing knowledge of the role of research and data collection in the management of Victoria’s marine resources.
– Discussion and presentations introducing key intertidal species, intertidal communities, concepts regarding food webs and species interactions and the influence of abiotic factors in the coastal/marine environment.
– An (ecological) area study introducing students to field observation, data recording techniques, species identification, classification and environmentally responsible behaviour.
– Practical experience in gathering species distribution and abundance data using quadrat surveys, data collection and data interpretation.
Inclusions and Notes
Restrictions: Delivery of program is tide dependent. Please provide alternative dates that spread across at least two weeks.
Prior knowledge required: A short preparatory exercise will be provided to classroom teachers to be undertaken by students in advance of their field trip to Ricketts Point. The material is pertinent to enabling students to adequately engage with field studies on the day. The preparatory material will provide students with a background understanding of key abiotic factors and their impacts in marine and coastal environments and species adaptations.
Some degree of understanding of food webs and trophic levels and homeostasis and osmoregulation will be advantageous for students. Familiarity in the use of dichotomous keys, species identification charts and scientific nomenclature will be helpful as would be knowledge of data collection techniques including quadrat surveys.
The sampling techniques used in this program are based Parks Victoria Sea Search moderate-level of difficulty sampling method for intertidal reefs. It is recommended teachers and students review intertidal species identification charts for Ricketts Point Marine Sanctuary and quadrat sampling methods (found at https://www.parks.vic.gov.au/get-into-nature/volunteering/sea-search).
Equipment needed: A copy of workbook, clipboard and pencil per student. Appropriate clothing and footwear (long sleeve top, long pants, jacket, hat/beanie, soft-soled shoes e.g. runners). Students will need a snack/lunch and water.
Equipment supplied by Gould: Tape measure, quadrats, algal dichotomous keys, species identification charts.
VCE Biology Unit 1 (Area of Study 2/Outcome 2)
Survival through adaptations and regulation
– The structural, physiological and behavioural adaptations that enhance an organism’s survival and enable life to exist in a wide range of environments
– Successful adaptations as models for biomimicry to solve human challenges
– How regulation of factors is needed to maintain a relatively constant internal environment, explained by the stimulus-response model and the use of homeostatic mechanisms including feedback loops
– Classification of biodiversity, past and present, into taxonomic groups based on shared morphological and molecular characteristics, and naming using binomial nomenclature
Relationships between organisms within an ecosystem
– The beneficial, harmful and benign relationships between species including amensalism, commensalism, mutualism, parasitism and predation
– Interdependencies between species as represented by food webs, including impact of changes to keystone species
– The distribution, density and size of a population of a particular species within an ecosystem and the impacts of factors including available resources, predation, competition, disease, chance environmental events, births, deaths and migration.
VCE Biology Unit 1 (Area of Study 3/Outcome 3)
– The characteristics of scientific research methodologies and techniques of primary qualitative and quantitative data collection relevant to the investigation: laboratory work (microscopy), fieldwork (quadrats, transects and field guides) and/or observational studies of animal behaviour; precision, accuracy, reliability and validity of data; and minimisation of experimental bias.
