    Climate change

    Since 1990, New Zealand’s agricultural greenhouse gas emissions have grown by about 1% each year. Intensified farming has led to added emissions of nitrous oxide and methane in particular.

    Climate change – as a wicked problem – can form a rich real-life context for developing students’ thinking, visioning and problem-solving skills, action competence and an array of key competencies.

    Focusing on one main issue – the science and innovations of reducing dairy sector greenhouse emissions – can provide an opportunity for students to develop a deeper understanding.

    History of dairy farming in New Zealand

    Dairy farming has changed significantly over the centuries from hand milking to machine milking. The size of farms and the expectations on farmers have also changed with time.

    There is no doubt that agricultural intensification can come at a cost to the environment. However, we need to balance this cost with the importance of food production. As the Earth’s population grows, so does the need for farmers and others to produce more food.

    For younger learners

    One aspect of DairyNZ’s education and extension programme is supporting our youngest learners to engage with and learn about dairy farming in New Zealand. There are opportunities for cross-curricular learning.

    Rosie’s World is a safe, fun site designed to entertain kids and help them learn about dairying.

    These Rosie’s World links provide some engaging resources pitched especially for younger learners.

    Environmental factors

    The environmental concerns associated with farming are often the subject of media reports and emotive debate. It is the role of scientists to provide reliable information and data concerning farm practices and potential environmental impacts.

    Provide an opportunity for students to dive deeper into the information and make sense of the complexities within it. Scaffold their understanding of concepts such as nutrient cycling and interdependence as well as exploring socio-scientific aspects.

    Dairy farming as a context for learning

    Learning on the farm creates opportunities for students to experience practical learning as well as reinforcing knowledge.

    Learning about farming in an urban classroom provides opportunities to explore an industry that is embedded in New Zealand innovation and history.

    Agriculture has a diverse curriculum including economic, historical, social and cultural influences on primary production and the interrelationships of science, technology, society and the environment.

    These resources will provide some tools to support teachers exploring aspects of dairy farming in the classroom:

    Dairy research development and innovations

    The industry recognises the crucial role it plays in protecting the environment. Research and innovation is vital to ensuring the industry continues to improve practices and minimise impacts on the environment while producing an important product – milk.

    Ruminant digestion

    Ruminants are mammals with specialised digestive systems that use fermentation processes to gain nutrients from plant material. Cattle, sheep, horses, deer, goats and camels are all ruminants.

    Each part of the digestive system from the mouth to the intestine has a part to play in the breakdown of plant material. The adaptation that sets ruminants apart from other animals is their complex multi-chambered stomach comprising the rumen, omasum, reticulum and abomasum.

    Cows are an amazing species, turning something that a human could never eat into something that is really, really nutritious and allows them to produce a lot of milk and grow babies.

    Have a look at DairyNZ’s FeedRight resources for a more in-depth look at ruminant digestion.

    Te ao Māori perspectives

    The dairy industry recognises the crucial role it plays in improving and protecting water quality and mitigating greenhouse gas emissions. As stewards of the land, many farmers are working to protect, restore and enhance the environment, an approach that aligns with kaitiakitanga – guardianship and care for the environment. Other perspectives to consider are the roles of mātauranga Māori and whakapapa (interconnections).

    Pasture and soil

    Soil – it’s much more than dirt. Soil keeps us alive. Without soil, we would be hungry, thirsty, naked, homeless and breathless.

    It is important in science to not only build students’ knowledge and understanding of science but to support them to make connections between science concepts and the world around them. Soil and pasture is an ideal context for this as it links to many other aspects of science as well as global and local issues such as growing food and farming practices.

    The students thought ‘dirt’ was pretty boring until their eyes were opened to ‘soil’ and what lies beneath the ground. They were fascinated to discover roots, glass, worms and clay. What made a huge impact on them was how important soil is to us and the world in which we live.
