Stage 3 Science and Technology: Environment Matters Effects of human activities on the environment Stage 3 Foundation Statement Students independently develop questions for scientific investigation, conduct scientific investigations based on fair testing and collect, record and analyse the resulting data. They identify trends in data, evaluate findings and prepare possible explanations. Students use, select and evaluate equipment, computer-based technology and other resources to meet the requirements and constraints of investigations. Students independently plan, implement and manage the design process and evaluate the results using design criteria. They consider the implications of design and production in relation to environmental, aesthetic, cultural, ethical safety and functional factors. Students select, safely use and evaluate equipment, computer-cased technology and other resources to meet the requirements ad constraints of design tasks. Students identify, describe and evaluate interdependent relationships between living things and the environment within ecosystems. They identify and describe various sources, forms, uses, transfers and changes in forms of energy. Students explore how natural forces and human interaction cause changes to the Earth over time. They recognise that the Earth is the source of most materials, and resources must be managed for sustainability. Students recognise that built environments are systems created to meet the needs and requirements of people and communities. They identify techniques used to engage audiences and convey meaning when creating information products. Students explain how production processes have changed over time and model systems used to manufacture products and provide services.

Outcomes – Learning Processes Investigating INV S3.7 Conducts their own investigations and makes judgments based on the results of observing, questioning, planning, predicting, testing, collecting, recording and analysing data, and drawing conclusions. Designing and Making Using Technology DM S3.8 Develops and resolves a design task by planning, implementing, managing and evaluating design processes. UT S3.9 Evaluates, selects and uses a range of equipment, computerbased technology, materials and other resources to meet the requirements and constraints of investigating and designing tasks. Outcome LT S3.3: Identifies, describes and evaluates the interactions between living things and their effects on the environment. Indicators • Predicts outcomes of seed growth tests, undertakes tests, documents findings and shares conclusions. • Undertakes a detailed observation of an insect colony, develops questions and plans nondestructive tests to collect more data. • Plans and manages the construction of a bush food/vegetable garden, identifying and resolving the need for funds and expert advice. • Develops a detailed plan to conserve or improve a local nature reserve/park using a simple scale, symbols and annotations. • Uses a water testing device to check the water pollution level in a local waterway and discusses findings, eg with an expert. • Selects the most appropriate medium to record and investigate local plants used by an Aboriginal community. • Prepares arguments about the potential effects of a new technology on living things after viewing a newsclip, eg the bionic ear.

Weeks 2–3 Design and make a product to satisfy an identified need, taking into account environmental costs. Weeks 4-5 What do we already know about the effects of human activities on the environment? Brainstorm using mind map, etc. Share a story, visual text, sites on the internet based on the Unit to build up background knowledge. Encourage children to share what they already know about the unit with others. What are our Outcomes? What do we hope to learn by the conclusion of the Unit? Title Page. Whole Class : Evaluate how selected products satisfy human needs. Outline the environmental impact of the item’s production. Include packaging, production methods, the product’s use and eventual disposal. Children form into groups and select product. Design modifications to minimise the effects on the environment, eg an environmentally sound product may be poorly packaged, a simple object may be made of rare rainforest timbers. Describe the design problem, including environmental requirements. Generate ideas using drawings, words or both. Outline solutions or make a model of the product. Include disposal procedures. Research large-scale production methods. Analyse the design solution, identifying its strengths and weaknesses. How is the item received by others? Get an expert opinion. Present your proposal/ suggestion to the original producers. Report back to class. Investigate the effect of human activity on environments both in Australia and the rest of the world. Share Information texts, visual texts, etc and identify characteristics of natural environments, include plants and animals in particular areas. Visit national parks, watch videos, etc. List human activities that interact with/ impact on natural environments, eg land for farming; hunting/ fishing; mining; urban development; use of resources; quality of air/water; use of pesticides, cars/planes. Suggest effects of identified activities, eg farming leads to reduced natural habitats/animal food sources. Directly observe and critically appraise effects of human activity, eg soil salination, air/water pollution, species endangerment. Use reference materials. Research causes of problems, identifying as many reasons as possible, eg species endangered through habitat destruction, introduced species, hunting. Date Week 6 Weeks 7-8 Revision and Catch Up Design and implement/maintain a system to recycle materials within the school. Week 9 Present pros and cons of human activity. Explore conservation in traditional Aboriginal societies. Make predictions for the future, eg forest felling causing species extinction, green house effect. Examine current waste disposal in the school. (If a recycling system already exists, evaluate its function.) Trace where waste products go. Measure the amount of rubbish thrown away in a day, a week. Evaluate the effects of this on the school and wider community. Identify materials that can be recycled, eg food scraps, paper, plastic containers, glass, and aluminum cans. Separate materials that can be usefully reused within the school, eg yoghurt pots. Organise recyclable materials into those to be recycled at school, eg food scraps made into compost and materials that can be sent to a recycling service, eg paper, glass. Define the purposes of recycling system, eg to gather suitable food scraps and organise compost area. Generate ideas and illustrate the steps of the system. Consider location of rubbish collection points, ways of encouraging their use, systems for separating different materials, storage, and collection by outside agencies etc. Include an ongoing management plan that may allow for shared responsibility. Trial the plan over a period of time and evaluate its effectiveness. Make changes as required. Compare amounts of ‘rubbish’ thrown away before and after implementation of the plan. Investigate the ways people, worldwide, are addressing the problems of environmental damage. Review the range of effects human activities have on natural environments. Evaluate the necessity of human activities, eg farming is harmful to indigenous plants/animals, but necessary to provide food. Use arguments to justify judgments. Classify consequences as preventable or able to be addressed. Propose ways of preventing problems. Research current means of addressing problems using pamphlets, organisations, and references. Areas of enquiry may include: Identify and contact concerned organisations, eg ACF, State Pollution Control Commission. Discover aims, activities, etc. Contact government agencies and explore legislation or statutory requirements/controls Make judgments about their effectiveness. Suggest ways of reducing use of resources and waste. Research recycling systems. Identify actions being taken in the local community, state, and other countries. Explore the roles and functions of zoos and botanical gardens in protecting animals and plants under threat. Evaluate methods/solutions suggested. Consider their complexity, expense, and applications to other situations. Propose ways that individuals can have some effect. Assess how current activities are changing society’s attitudes and actions. Reflect on whether ‘technology’ is a destructive force or is it part of the solution to environmental survival? Investigate the use of renewable and non-renewable resources. Research the availability of this service, such as how frequently garbage is collected, are recycled paper/plastic/ bottles collected etc. Make a list of everything your family has thrown out in one day (or go through your trash can in the house — this may have taken a couple of days to accumulate). Make a second list which shows how many of these items have only been used once. Have students brainstorm/design items which do not use up our fossil fuels and other non-renewable resources. Research how some of the thrown-away material is manufactured (eg plastic detergent containers, poppers, aluminium cans). Do a flow chart showing how it goes from manufacturer to the store. Don’t forget to include raw materials, energy use, paper cartons and plastics for wrapping, fuel used in transporting the raw materials and finished products to market. Find out what processes create pollution of one kind or another. What type of pollution does the power create? What type of pollution or toxic waste is created in the manufacturing of the plastic and the paper from pulp (investigate atmospheric, ground water, and surface water). What impact does logging/mining have on loss of top soil, animals losing their habitat, extinction of species, or the quality of life of future generations? Investigate what health effects are caused by these toxic chemicals entering the environment. Research some of the ways in which local councils or the State Pollution Control Commission, Water Board and Department of the Environment remove the toxic waste. Revision Week 10 Reflect on the mind map, etc from Week 1. Now, in another colour, add what else the class has learnt on this topic. Evaluate unit and allow time for children to reflect over their work and to summarise in their own words what their greatest learnings were throughout this unit.
