This resource material aims to help teachers and students in secondary schools investigate and understand more about primary industries in Australia.
The objectives of the educational resources are to:
- Support Primary Industries Education Foundation Australia and its members in expanding awareness about primary industries in Australia by engaging and informing teachers and students about the role and importance of primary industries in the Australian economy, environment and wider community.
- Provide resources, which help build leadership skills amongst teachers and students in communicating about food and fibre production and primary industries in Australia.
- Develop educational resources that can be used across Australia to provide encouragement, information and practical teaching advice that will support efforts to teach about food and fibre production and the primary industries sector.
- Demonstrate to students that everyone can consider careers in primary industries and along the supply chain of food and fibre products.
- Develop engaging learning programs using an inquiry process aligned with the Australian Curriculum.
- Develop in school communities, an integrated primary industries education program that emphasises the relationship between food and fibre industries, individuals, communities, the environment and our economy. These educational resources are an effort to provide practical support to teachers and students learning about food and fibre production and primary industries in schools.
About the approach
Several key principles underpin the theoretical and practical application to this unit. Students are guided to:
- Search for information using both digital and non-digital means
- Use research techniques and strategies
- Use thinking and analysis techniques
- Present findings to a real audience, and
- Reflect both on the product created and the process undertaken.
Rather than seeing knowledge as something that is taught, the emphasis in this unit is on knowledge and understanding that is learned. The unit involves students in:
- Working from a basis of their prior knowledge and experience
- Seeing a real task or purpose for their learning
- Being directly involved in gathering information firsthand
- Constructing their knowledge in different ways
- Presenting their learning to a real audience
- Reflecting on their learning.
This is a unit developed with a learning sequence to look at two connected streams of science. Firstly the development of practices in agriculture to improve yields and sustainability, and secondly to understand the connections of science through disciplines, including the role of reproductive technologies in the primary industries. There is a focus on Biotechnologies.
The resource is designed with learning experiences. This is to provide you with content to cover, but over time frame that is flexible to your classroom and school set-up.
In this unit, students:
- Explore past and present methods/practices in modern farming
- Investigate technological developments that have been applied to modern farming to improve yield and sustainability
- Develop an understanding of how science can connect through disciplines
- Develop an understanding of the variety of reproductive technologies and how these are applied in science and the field of primary industries.
- Investigate and present findings on types of technological developments in reproduction and where they are use
- Explore and evaluate knowledge regarding GMO and consider different claims and explanations from a range of difference perspectives
Based on Australian Curriculum, Assessment and Reporting Authority (ACARA) materials downloaded from the Australian Curriculum website in February 2015. ACARA does not endorse any changes that have been made to the Australian Curriculum.

Teacher Background information
Agriculture (also known as Primary Industries) is an innovative industry. Innovation has often been driven as a consequence of being in a difficult situation and needing to find a new way to do something.
There are many examples of innovation and development of technology in primary industries that include: new farming tools, new farming methods, new varieties of plants, new breeds of animals, new scientific discoveries, and applied technology from outside the field of science, for example GPS in tractors. Here is a case study on how technology is improving the detection of protein in grains, and why this is important to crop development and humans.
Case study - Analysing protein in grains
Why is protein important in grains and for humans?
Protein is a macronutrient needed in relatively large amounts by the body. Protein is an essential component of every cell in the body and helps to build and repair tissues. Protein that you eat in your diet, when digested by the digestive juices in your stomach and intestines break the protein down to basic units called amino acids. The amino acids then make the proteins work to make enzymes, hormones, and are the building block of bones, muscles, cartilage, skin and blood.
Scientists have identified 22 amino acids that are very important to human health. There are 13 amino acids that your body can make, and 9 that you need to consume. These 9 amino acids are essential and can be found in animal sources such as meat and milk. Meat and milk contain all 9 essential amino acids, however vegetarians can also get all 9 essential amino acids by eating a wide range of protein-rich vegetable foods.
So, how is protein measured?
The way in which protein is measured was using the level of nitrogen, and then a conversion factor was applied. In the past, methods used to analyse protein content in grains involved detailed analysis using wet chemistry. The Kjeldahl Method was developed in 1883 by Johann Kjeldahl. The following article outlines the method. Watch on YouTube how to measure using Kjeldahl method
In that last couple of decades methods have been developed over time to reduce labour and time, and allow greater accuracy. Current methods include Near Infrared (NIR) spectroscopy. Near infrared spectroscopy is the measurement of the wavelength and intensity of the absorption of near infrared light by a sample, in this case a crop variety such as wheat. The following websites outline information about NIR
- Commercial portable NIR protein analysis
- Review of different methods
- Commercial company conducting protein and seed analysis
This information and development of technology has been important to the application of fertilisers and development of new crop varieties that produce higher protein content.Download Worksheet 1
- Provide worksheet 1 for each student
- Internet access
- Digital device
- Students to review a primary industries timeline looking at technologies developed over time to improve yields and sustainability. Historical developments in primary industries - historical experiments compared to current methods emerging)
- Provide students with worksheet 1 and get students to have a look at the following website
- Using the following (or similar) website develop a timeline. (Alternatively for a no-tech activity, you could map this with the class on paper)
- Can the students identify a pattern in the rate of change over time? I.e. Change happened slowly in early development, and accelerates in recent times since the 1700’s but prior to that time scales and developments occurred over a greater timescale. Discuss with the students why this may be the case
- Students will need to research recent primary industries technologies. They will then need to include on their timeline an additional 5 new technologies developed over the last 10 years that has lead to improved yields and/or sustainability. They can choose marine or terrestrial production systems. Suggestions of these include: biotechnology including gene technology, precision agriculture, drought resistance, data analysis, NIR technology etc. Some websites are included in the resources below.
- To complete this activity students will need to evaluate and identify which technology was the most significant ‘game changer’ (from their research) to the primary industries sector. Ask the students to support with the science information they have gathered. They can record on worksheet 1. They will need to communicate this with the class.
Optional activity to help students understand how to analyse protein
- Teachers that are chemistry trained may like to set up the Kjeldahl Method as a demonstration. The following website identifies a method. You could then show students the promotion video about on the commercial portable NIR protein analysis to see the difference in analysis techniques

Teacher Background information
Evolution of crops
For thousands of years’ farmers, gardeners and professional plant breeders have been breeding plants and animals to develop varieties with more desirable characteristics. Characteristics (or traits) such as improved yield, quality (taste and looks), pest and disease resistance and the ability to grow in various environments and climate conditions. New varieties have been achieved through the employment of different plant breeding techniques some of which have been practiced since near the beginning of human civilisation such as selecting plants with desirable characteristics for propagation. Farmers would employ these as progenitors for subsequent generations, resulting in an accumulation of desirable traits over time. Other techniques include interbreeding (crossing of closely or distantly related individuals to produce new crop varieties), classical breeding/hybridisation (the homologous recombination between chromosomes to generate genetic diversity) and more recently molecular breeding.
Molecular breeding involves using techniques of molecular biology to select, or in the case of genetic modification, to insert, desirable traits into plants. This process involves the application of biotechnology. Varieties developed this way are referred to by a number of names including genetically modified.
Modifying the traits of plants genetically came about when in 1886, scientists looking at organisms on a cellular level which lead to the discovery of deoxyribonucleic acid (DNA) - a molecule that contains all the information to determines each trait of the plant). Since then studies of gene technology has taken off. Gene technology is the term given to a range of activities concerned with understanding gene expression, taking advantage of natural genetic variation, modifying genes and transferring genes to new hosts (Ref).
With advancements in our understanding of genetics scientists believe that significant improvements can still be achieved by means of genetic modification.
The following resource written by Agricultural Biotechnology Council of Australia is a very good resource: http://www.abca.com.au/wp-content/uploads/2014/03/The-Official-Australian-Reference-Guide-to-Agricultural-Biotechnology-and-GM-Crops_2nd-edition.pdf
It is interesting to have a look at the ancestors of the food we eat today before plant breeding allowed them to develop into the varieties of which we are familiar today. The following website takes a closer look at this.

Learning Experience 3
The lesson will provide students with an understanding of how science can connect people through disciplines
Students will be able to:
- Identify and match information relating to different areas of science.
- Understanding problems across industries and how solutions are being found
Teacher Background information
Science discoveries can come from surprising places and collaboration from people from all different walks of life. It has been through collaboration that many of the innovations in science have been developed:
- Discovery of radium by Marie Curie
- Newtons Law of Gravitation
- Evangelista Purkinje – discovered fingerprints in 1823
- Michael Faraday – discovered electricity in 1821 and 10 years later created the first generator
Expanding on different science discoveries:
Probably the most important “accidental” discovery was penicillin. It was discovered in 1928 when Sir Alexander Fleming, a Scottish biologist who was studying the bacterium staphylococcus, left his petri dishes stacked on a bench while he went on holiday. When he returned, he noticed that a mould in a discarded petri dish (which he identified as Penicillium notatum) was growing in such a way that it dissolved all the bacteria around it. Fleming didn’t even hold out much hope for his discovery: it wasn’t given much attention when he published his findings the following year, it was difficult to cultivate, and it was slow-acting – it wasn’t until 1945 after further research by several other scientists that penicillin was able to be produced on an industrial scale, changing the way doctors treated bacterial infections forever. Penicillin antibiotics are historically significant because they are the first drugs that were effective against many previously serious diseases such as syphilis and Staphylococcus infections.
The adhesive behind Post-it® notes was discovered in 1968 by Spencer Silver, a researcher at 3M Laboratories, who was actually looking for a stronger adhesive than what was currently available. Instead, he found a weaker one, an adhesive that stuck to objects but could be pulled off without damaging them or leaving a residue. A few years later his colleague at 3M, Art Fry, spread the adhesive on small pieces of paper to mark and re-mark his place in his choir hymnal. When he started using the small pieces of paper at work, colleagues came by to borrow some, and the Post-it note was born.
In 1839, Charles Goodyear was looking for a way to fix the current flaws of rubber, which solidified and cracked in winter, and melted in the summer heat. But Goodyear discovered vulcanised rubber quite by accident when he happened to spill a mixture of rubber, sulfur and lead on a hot stove. The mixture charred and hardened, but the rubber was still malleable enough to be usable. He patented his vulcanisation process in 1844, long before the age of automobiles. Years later, in 1898, the men who started the Goodyear Tyre & Rubber Company named it after the man who made their business possible.
The concept behind the thermal ink-jet printer was discovered by accident in 1977 when an engineer at Canon in Tokyo, Ichiro Endo, rested a hot soldering iron on a syringe, which held ink, causing the syringe to eject the ink. This concept eventually became the mechanism behind the first BubbleJet printer.
Have you heard of Friedrich Miescher? Miescher first identified and isolated DNA (called nuclein) in 1869. It was nearly 100 years later in 1953 that Watson and Crick first discovered the double helix structure of DNA.
Discoveries shape humanity, and many people have thought philosophically about this providing many thought provoking quotes including:
‘Mistakes are the portals of discovery’ – James Joyce
‘Somewhere, something incredible is waiting to be known’ – Carl Sagan
See the following website for more details: Life changing science discoveriesDownload Worksheet 3
- Copy of the student worksheet 3 for each student
- Provide a copy of the student worksheet 3 for each student.
- Discuss with the students content from the teacher background. Using the background information, list (dot points) with students on worksheet 3 some of the science knowledge obtained through connecting ideas across the disciplines of science.

- review and be familiar with reproductive technology terminology
- be presented with information on gene technology and Genetically Modified Organisms (GMO)
- gain some understanding gene technology through completion of a corn plant transgenic example
Teacher Background information
Biotechnology includes the discovery of genes (genomics), understanding gene functions and interactions (functional genomics), the use of DNA markers and genetic modification, which includes controlling gene activity, modifying genes and transferring genes to new hosts. Gene technology is a key aspect of Biotechnology.
Gene technology is the term given to a range of activities concerned with understanding gene expression, taking advantage of natural genetic variation, modifying genes and transferring genes to new hosts. http://www.csiro.au/en/Research/Farming-food/Innovation-and-technology-for-the-future/Gene-technology/Overview
Directly inserting or deleting one or more genes, or turning them on or off (these processes are collectively referred to as genetic modification, genetic manipulation or genetic engineering. The resulting crops may also be referred to as ‘transgenic’).
The full definition of a Genetically Modified Organism (GMO) appears under section 10 of the Act (Ref). In essence, a GMO means:
- an organism that has been modified by gene technology; or
- an organism that has inherited particular traits from an organism (the initial organism), being traits that occurred in the initial organism because of gene technology.
- Provide a copy of worksheet 4.1 to all students
- Projection of video to view web content and sound
- Worksheet 4.2 provides solutions
- It is import to get the students familiar with the terminology surrounding reproductive technologies. First watch this video that provides an introduction to genetics and evolution. Get the students to review the following website on gene technology terminology. Provide a classroom list of definitions. This list should be an evolving list over the course of the learning experience.
- Read through the definition of GMO with the students. Get them to think about any questions they have of the definition. Ask them to share their questions. Write these down for the class to see as a group and compare and synthesis to common questions the class would like to answer. Spend 20 mins, answering these questions and keep the list available if there are unanswered questions to continue to answer.
- This is a great video on explaining GMO.
Please note it doesn’t show the whole video (only 4mins 20), however the video that is released covers content relevant to this topic. You can get a free 5 day trial that you could sign up to view the remaining content (but is not necessary for this exercise)
- The following website has a number of good resources that you may like to use in your classroom. The following sections in particular are worth viewing. This content is for year 11/12 students and you may need to assist with explanations. The website has a good glossary.
Watch the wheat breeding techniques (6/8) and answer the questions outlined on worksheet 4.1
Other excellent videos on this website include:
2/8 Traditional techniques
5/8 Recent developments in tomato breeding
8/8 – conclusion – this is a good summary video and supports the use of gene technology for feeding the growing population
- The next exercise refers to Transgenic Technology.
- To complete ‘creating transgenic corn’ in Worksheet 4, you will need to provide students with information on transgenic technology. See Transgenic Infographic given in Learning Experience 5.
- Provide students with a definition of transgenic such as ‘transgenic is a term that describes an organism containing genes from another organism put into its genome by artificial means.’
- Each student to complete the transgenic corn exercise will need:
- A white copy of the corn DNA
- A copy of the pink Agr DNA (Agr – Agrobacterium sp.)
- 2 different colours (highlighters or pencils)

Learning Experience 5
The lesson will provide students with an understanding of reproductive technologies and how to graphically represent their research
Students will be able to:
- conduct research into one area of reproductive technology
- represent the summary of information collected
Teacher Background information
Information graphics or infographics are graphic visual representations of information, data, or knowledge intended to present information quickly and clearly. Infographics have evolved in recent years to be for mass communication as they can easily communicate large amounts of information.
Infographics can be created by hand using tools such as graph paper, pencils, markers and other stationary. However computer software is now widely available in being able to produce infographics. A simple search of ‘infographics’ in Google will provide you with some possibilities
The following two videos on Scootle may assist students with their content for the infographic.
The first video is about cyanobacteria and using genes identified to help with other crops such as wheat
The second video is called ‘genetically modified organisms, 1999’ http://www.scootle.edu.au/ec/viewing/R9194/index.html. The transcript provides further information which is where the below information came from.
Remember what they said about the peas and beans. Here is what was recorded in the educational content below the video:
‘The development of the genetically modified peas shown in this clip was discontinued after tests showed that the peas caused an immune response in mice. Beans are resistant to the pea weevil because they produce a protein that inhibits one of the weevil's digestive enzymes. The gene coding for this protein was transferred to the peas, but the peas produced a protein of a slightly different structure. Although it inhibited the weevil enzyme in the same way as the bean protein, it produced a different immune response in mice.’
- Paper to record ideas and drafts
- Items and tools to create infographics, pens, magazines
- Provide paper or worksheet 5
- Get students to develop one infographic on a reproductive technology (worksheet 5). Students can choose from the listed types of gene technology below.
- Students must provide a real life example of how the technology is used.
- Timing for this activity is flexible. You may just get students to develop a draft or take it through to completion.
- Splicing (Splicing Ex 1)
- Cloning (Cloning Example 1, Cloning Example 2)
- Selective breeding (Selective Breeding Ex 1)
- Marker assisted (MA Ex 1)
- Transgenic technology (Transgenic Tech Ex 1)
The infographic may be:
- an IT design (interactive or static),
- a collage
- hand drawn or
- composition of above ideas
Teachers will need to provide students with paper and items/tools/ access to computers to create their infographic. There are a couple infographic examples and free tools below. Here is one website you can direct students to: www.canva.com/create/infographics
- The infographic will need to use an example from primary industries/fisheries to describe how technologies have been applied to modern farming techniques
- An infographic assessment rubric (Resource 1) is included to assist with marking students’ work.
