These teacher guidelines do not need to be submitted for moderation. Context/setting In this activity students are expected to complete a written report on the impact of an introduced species on a native species or native community using resources provided in the classroom. Conditions Students will be given class time to complete the activity. Resources will be supplied. Insert the conditions, including time available / due date, on the activity. Resource requirements The teacher will need to collect and photocopy a range of resources on the effects and management of introduced species. Additional information The activity can be modified to suit the resources available or the interests of the students. © Crown 2006 2 Internal assessment resource reference number Bio/1/5 – A4 PAGE FOR STUDENT USE <<Insert your school name here>> “Introduced species versus native species” Supports internal assessment for: Achievement Standard 90165 version 2 Describe the control of an introduced species that affects native species Credits: 2 Student Instructions Sheet Conditions <<insert information on the conditions eg time allowed, resources available>> Instructions Use the class resources to produce written report on the management of an introduced plant or animal that causes harm to a native species or native community. Your written report must include the following points: 1. Common or scientific name of the introduced plant or animal. 2. Common or scientific name of the native plant or native animal or native community that is harmed by the introduced organism. 3. Discuss the effects of the introduced plant or animal on the individuals and the population of a native plant or native animal or native community. 4. Discuss the use and effectiveness of two methods use to control the numbers of the introduced plant or animal. © Crown 2006 3 Internal assessment resource reference number Bio/1/5 – A4 PAGE FOR STUDENT USE Assessment schedule: AS90165 version 2 Bio/1/5 – A4: “Introduced species versus native species” To determine the overall level of performance the judgement at the top of the column must be met. For each judgement, evidence can be obtained from anywhere in the report. Text in bold font includes both the key aspects of the judgement and differences between the levels A, M and E. Judgement for achievement Judgement for achievement with merit Judgement for achievement with excellence Report on a named introduced species and named native species contains descriptions of all three of: - effects on native species / population - how two control methods are carried out - effectiveness of two control methods. Report on a named introduced species and named native species contains explanations related to aspects of any of: effects on population OR how two methods of control are carried out OR the effectiveness of two control methods. Report on a named introduced species and named native species contains discussion related to aspects of any of: effects on the population OR how two methods of control are carried out OR the effectiveness of two control methods. Example of evidence for achievement Example of evidence for achievement with merit Example of evidence for achievement with excellence e.g. The German wasps eat the honeydew that would normally be eaten by the native bats. This reduces the food supply available to the bats. Petrol is poured down the nest of the German wasp. The fumes kill the wasps in the nest. This means that the wasps are now not eating the honeydew that the bats need. e.g. The German wasps eat the honeydew that would normally be eaten by the native bats. This reduces the food supply available to the bats and the bats have to compete against other organisms for other food sources which may not be as good a quality or as plentiful as the honeydew. Petrol is poured down the nest of the German wasp. The fumes kill the wasps in the nest. This means that the wasps are now not eating the honeydew that the bats need. The fumes from the petrol will kill that one colony but all the other colonies in the area would need to be found and given the same treatment. When poison bait is used the worker wasps from many colonies will take the bait back to lots of nests. This is more effective because you don’t have to find all the nests to kill them. Eg The German wasps eat the honeydew that would normally be eaten by the native bats. Petrol is poured down the nest of the German wasp. This is method is used to try to kill out the whole hive quickly. This is not always effective. Poisonous powder can be used to kill the wasps. The powder is placed around the opening to the nest. As the wasps enter the nest they take some of the poison down into the nest. This method is effective © Crown 2006 Poisonous powder can be used to kill the wasps. The powder is placed around the opening to the nest. As the wasps enter the nest they take some of the poison down into the nest. 4
