Introduction

Units of work involving the environment enable your students to immediately apply their learning in the real world, giving them greater motivation and opportunities to excel. 

You should find that the curriculum materials are designed to meet a wide range of educational needs throughout Australia including:

1.     Australian Curriculum

2.     Other state curricula

3.     Latest innovations in learning and teaching practice e.g. Principles of Learning and Teaching (PoLT)

4.     The Victorian e5 instructional model – engage, explore, explain, elaborate and evaluate

5.     The curriculum component of AuSSI – the Australian Sustainable Schools Initiative

6.     Education for a Sustainable Future, Australian Government

You will find everything you need to organise a curriculum unit on Solid Waste for Years 5 and 6 in the teacher Curriculum section of the website.  Student research materials can be found under Student Toolbox in the top menu bar along with self directed activities and various tools.

Find what you need by selecting the year levels and topic.  Otherwise, use the built-in search engine.

All units of work developed on this site integrate English, Science, Geography and Mathematics. 

Over the next two years, Cool Australia has big plans to fill the Student Toolbox sections of the website with hundreds of incredible learning resources.  Please keep referring back to these areas.

We always appreciate both student and teacher feedback.  If you find anything that may require minor changes, please contact us know as it only takes us a few minutes to make corrections.

 

Inquiry learning

A model of Inquiry learning has been chosen for the design of the Cool Australia units of work, as it can be used to incorporate and accommodate all the various educational changes and innovations to curriculum and teaching practice that have occurred over the past ten years.  It is also recommended by The Australian Government’s current document Education for a Sustainable Future, 2005.

Cool Australia’s Inquiry Learning approach has been divided into the following sections: Prior learning, Tuning in, Finding out, Drawing conclusions, Finding solutions, Considering social action and Reflection and evaluation.

Prior learning

Prior learning activities enable students to value what they already know about a topic.  While they establish what students already know, they also help the teacher to identify some of the student’s misconceptions.  Prior learning activities can be used at the start of the assessment process.

Tuning in

Tuning in activities helps students to define and focus on the issues they will be dealing with in the unit of work.

Finding out

Finding out activities help students to obtain more information about the issues they are going to investigate.  They can use them to identify questions of interest and research these either in small groups or on their own.  Once information is gathered, it can be shared using chosen communication methods e.g. short presentations.

Students can continue finding out by completing a range of investigations, including gathering data.  They can use appropriate methods to present and communicate what they have found out.

Drawing conclusions

Drawing conclusion activities provide students with tools that help them further develop their ideas and opinions.  They can describe issues from different perspectives and identify, examine and justify different points of view.

Considering social action

Considering social action activities give students opportunities to apply their learning in real world situations, in the classroom, school, home or the local community.

Reflection and evaluation

Reflection and evaluation activities provide students with the time and opportunity to reflect on what they have learnt and the learning processes in which they have been involved.

Student actions

Units of work involving the environment enable your students to immediately apply their learning in the real world, so they have greater motivation and opportunities to excel.  They become empowered as they discover their ability to create positive change for a better environmental future.

In designing the units of work, Cool Australia has identified the age appropriate actions for students so that as they grow older, they accept greater and more rewarding challenges:

Foundations years: Students learn to be responsible for their actions and belongings.

Years 1 and 2: Students take responsibility for their classroom.

Years 3 and 4: Students start taking greater responsibility for environmental tasks around their school.

Years 5 and 6: Students assist in creating change in their school and local communities.

Years 7 and 8: Students instigate and plan environmental projects and campaigns in their schools and local community.

Year 9 and 10: Students take initiatives in sustainability projects in their school and local community.

In this unit on Solid Waste, Years 5 and 6 students are provided with action-based activities that will enable them to:

  • develop a class safety plan for working with waste
  • conduct a solid waste assessment of the school
  • explore the 4Rs of minimising solid waste and how this relates to their school
  • investigate the solid waste management systems in their school
  • identify new ways for students and teachers to reduce solid waste around their school
  • produce ideas for reducing solid waste in the school and communicate these to the Principal
  • design and complete a waste reduction project for the school

 

Assessment and curriculum links

Assessment

Assessment background:  Many schools will have very prescriptive assessment policies.  Having assessment processes in place throughout a unit of work and involving students in their assessment, will assist teachers to meet these expectations.  The current overarching understanding of assessment is:

  • Assessment for learning will help teachers respond to students’ learning needs during the unit of work.
  • Assessment as learning occurs when students monitor their own progress and make learning choices.
  • Assessment of learning occurs when teachers use evidence of what students have achieved. Teachers are often obliged to measure this against Learning Outcomes or Standards.

 

To assist teachers, activities have been identified to assist with assessment.  Teachers will first need to decide what aspects of their curriculum they wish to assess.  This will be determined by their state or territories’ official curriculum policies and documents.  This in time may be superseded by the Australian Curriculum.

Teachers that use Cool Australia activities often use the following process to develop their assessment:

1.     Once the unit of work has been chosen, choose which learning outcomes, standards etc. that are going to be assessed.  Often this is around five items.

2.     Link the appropriate activities throughout this unit with the areas to be assessed

3.     Decide how students will be assessed during their learning

4.     If students are develop learning goals, then link the goals to the assessment

5.     Decide how individual student’s learning goals will be assessed

6.     Modify communication activities, so they are a neat fit with your assessment needs

7.     As the unit develops, choose self-assessment tools with which students are familiar for self-assessment

8.     Inform students at the start of the unit about their assessment requirements

 

Assessment ideas

A unit of work on an environmental topic will provide a range of tasks suitable for assessment.  Identify the tasks that best assist with the learning outcomes / standards etc you wish to assess. 

Develop two lists as follows:

1.     General – could apply to any unit of work on the environment using an inquiry learning approach

2.     More specifically – identifies activities in this unit of work that has tasks suitable for assessment

 

General

  • Use a prior learning activity to both find out what students already understand at the beginning of the unit, and to find out any misconceptions they may have.
  • When doing activities, students are able to respond to questions and can compare and explain other’s opinions.
  • Students produce informative texts.
  • Students present information or findings in a variety of ways, sometimes choosing the media.
  • Students use mathematical language and concepts to explain environmental issues and solutions.
  • Using the ‘Considering social action activities’, students apply their new understandings

More specifically

  • Use the activity sheets as you go through the unit to find out if students are learning new concepts.
  • As students collect data, ask them to explain what the data means.
  • Use the Student Toolbox to find out about a student’s research skills and their ability to present information.
  • Students design a solid waste reduction plan for the school.

Safety

The teacher needs to be aware of possible hazards in a unit on solid waste. It is recommended that the teacher prepares a risk assessment plan with common sense precautions, before starting the unit to minimise any risk to the teacher and the students. The students should be reminded of any relevant hazards before undertaking an activity. The students should also develop a class safety code. (The activity, Be safe with waste, has been designed for this purpose.)

Some possible hazards include:

Where Possible Hazards Precautions
Compost bins and worm farms
  • There are naturally occurring organisms, which can cause illnesses in people, in compost bins and worm farms. (People with allergies (e.g. asthma) and compromised immune systems are especially vulnerable.)
  • Students with allergies (e.g. asthma) and compromised immune systems should not play around nor do any activities with compost bins and worm farms.
  • All students should wash their hands after handling compost or working with worm farms.
 
  • There are many invertebrates that inhabit compost bins and worm farms. These are a normal part of the food chain in the bin. However, some of these invertebrates, such as spiders, scorpions and centipedes can bite if annoyed. The bite from a Red Back Spider is especially nasty and would require urgent medical attention.
  • All students should wear gloves when working around compost bins or worm farms.
  • Use compost bins and worm farms with lids.
 
  • Sometimes mice and rats can be found in compost bins and worm farms, where it is dark and warm and where there is an abundant food supply.
  • With compost bins, bury a ring of chicken wire or mesh (about 20 cms) below the bin to prevent rats and mice digging up into the bin.
  • Always cover food scraps in a compost bin or worm farm with a layer of soil.
  • If rats and mice appear, use appropriate rodent eradication treatments.
Bags of compost or mulch
  • As for compost bins or worm farms.
  • Follow instructions on the bags of compost – moisten compost before use, wear a face mask, wash hands after use.
Using garden tools
  • Obviously, garden tools are very useful, but they can be dangerous if used carelessly.
  • Train students to use tools safely and supervise their use
Waste audits /assessments
  • Waste studies often start with estimating the amounts and composition of the solid waste in a school. This is called a waste audit. However, to do a waste audit safely, a person needs to undergo formal training as there are many health hazards in working with waste. Examples of such hazards are viruses from paper tissues and cuts from sharp glass objects or needles.
  • A waste assessment is a much safer way of estimating waste amounts and composition, as the students are not touching the material. Explain to your students that these are just common sense steps, not undue cause for concern and worry.
  • It is strongly recommended that students do not do waste audits, which involve manually touching waste, even with gloves. (Students should never touch waste from unknown sources. The only exception to this would be when the class teacher provides clean and safe waste objects for an activity.)
  • Students should only do a waste assessment. Examples of an assessment could include taking photographs of rubbish and counting the number of objects in the top layer of a rubbish bin.
  • Students should always wear protective plastic gloves when doing a waste assessment.
  • With young children, the teacher may choose to do the assessment him or herself, demonstrating safe practices.
Outdoor observations
  • Rubbish in bins.
  • Students should not touch the material in rubbish bins. This is because you cannot be sure what is in the bin and who placed it there.
  • Careful supervision by teachers.
 
  • Injury from falls or touching sharp or hazardous waste.
  • Harm from outsiders to the school.
  • Develop outdoor safety code, especially a code if student spots a syringe in the school yard.
  • Students should always work outdoors in groups of 2 or more.
  • Careful supervision by teachers.
Outdoor observations near school skips
  • Rubbish in skips.
  • Students should not touch the material in rubbish skips. You cannot be sure what is in the skip and who placed it there.
 
  • Traffic – cars and collection trucks.
  • Clear rules that students should not go into areas where there may be vehicles.
  • Careful supervision by teacher.

 

Glossary

Biodegradable – materials that can be broken down by natural organisms, such as bacteria and fungi e.g. food scraps

Co-mingled – means all mixed up.  The term is used to refer to co-mingled recycling collections in which paper and cardboard, bottles and cans are all placed in the same recycling bin.

Compost – the material produced from a compost bin or heap.  This makes wonderful fertiliser for the garden.

Compost bin or heap – a container or area to hold food and garden scraps while they compost

Composting – Composting is the natural process of breaking down food scraps and garden waste, in a bin or heap, turning it into humus (rich soil) that can be used on the garden

Containers – things used for holding waste material (these can be boxes, bins, buckets or skips)

Contamination – occurs when the wrong materials are placed in a recycling bin or green waste bin.  This can cause major problems for the recycling company or composter.  For example, if a china cup is mixed in with glass drink bottles for recycling, it can ruin the batch of new glass.  Pieces of old fencing placed in a green waste bin may get tangled in the machinery at the composting plant.

Decompose – to breakdown.  This occurs in compost bins where food scraps and garden waste is broken down by naturally occurring microbes (bacteria and fungi).

Garbage – solid materials that are discarded to a landfill site

Green waste – waste produced from the garden – leaves, small branches, prunings and grass clippings

Hazardous waste – waste that is considered to be harmful to people or the environment and which must be disposed of separately, either by incineration or to special hazardous waste landfills

Humus – rich soil

Landfill site – a large hole or quarry where rubbish is buried.  These sites are carefully managed to prevent pollution of the air and waterways.

Litter – materials that are either thrown away or dropped by people.  Litter can end up on the ground, or in creeks, rivers and the ocean where it can looks messy and can harm people and animals.

Litter hot spot – a place where this an unusually large number of items of litter

Materials recovery facility (MRF) – a factory that takes materials that people put out in recycling bins and sorts them into different groups, bales them up and then sends them off to recycling factories where they are used to make new goods.

Midden – a mound where Australian aborigines placed their waste – shells, bones, old tools and weapons, etc.

Mulch – material used in a thick layer over the garden to prevent water loss.  Mulch can be made from a variety of materials, including pebbles, chipped wood, bark and leaves.  Mulch made from plant materials is different from compost, as it is not broken down.

Municipal solid waste – waste that is collected by local councils from the council operations and from homes

Non-biodegradable – materials that cannot be broken down by natural organisms, such as bacteria and fungi e.g. metals

Non-recyclable – an item that at the present time cannot be recycled back into either the same product or something different e.g. some plastics, nappies, tissues etc.

Organic waste – waste that is made up of either plant or animal matter – food scraps and garden waste

Recover – to collect something and either recycle, compost or reuse it, preventing it from going to landfill

Recyclable –  an item that at the present time can be recycled back into either the same product or something different e.g. a sheet of paper can be recycled into another sheet of paper or into a cardboard box

Recycle – the process of making something new from something that has been thrown away.  The new product can be the same as the old one or something quite different.  For example, a sheet of photocopy paper could be made into another sheet of photocopy paper (same) or it could be made into a cardboard box (different).

Recycling factories – factories that make new products out of recycled ones.  Sometimes the new goods are made out of all recycled material (as with some photocopy paper) and sometimes out of a mix of virgin (new) materials and recycled materials (as with cardboard boxes).

Reduce – buying and using things more carefully so that you produce less waste overall.  For example, if you buy one large box of cereal instead of two small ones, that means you will have less cardboard packaging overall.  Packing the right amount of food for your school lunch means that you will have less uneaten food to throw away after lunch.

Refuse – means to not do something in order to cut the waste you will produce.  A simple example of this is to not accept a plastic shopping bag from a shop assistant when you have bought only one small item.  Another example is to not use aluminium foil to roast potatoes in their jackets in the oven  

Reuse – to use more than once for the same or a different purpose.  For example, a girl might use a resealable bag for some biscuits for lunch one day and then take it home, rinse it out and use it over and over again to hold different sorts of snacks.

Rubbish – same as garbage

Solid waste – solid materials that are discarded.  This can include materials for recycling, green waste collection and for rubbish collections.

Trash – same as garbage

Waste – materials that are discarded– these can be a solid, liquid or gas

Waste management system – the containers in the school used to collect different types of waste and the processes used to deal with them

Wheelie bin – a special form of rubbish bin with two wheels, a lid and a handle.  They are very convenient for people to store solid waste materials and to wheel the bins to the kerb for the contents to be collected.

Worm farm – a special bin or mound that contains soil and compost worms.  Food scraps that are added to the worm farm are first broken down by microbes (bacteria and fungi) and then eaten by the compost worms, to produce warm castings that make wonderful fertiliser for the garden.
