Dr Selai Letica from AgResearch at Invermay is concerned about the nitrous oxide emissions that contribute to greenhouse gases. Nitrous oxide Greenhouse gases warm the atmosphere to make the ...
Phosphorus is a chemical element found on Earth in numerous compound forms, such as the phosphate ion (PO43-), located in water, soil and sediments. The quantities of phosphorus in soil are ...
In this activity, students investigate microbial presence in soil by building a habitat suitable for their growth. Known as Winogradsky columns, mud, newspaper and eggs create a variety of ...
In this activity, students learn about soil quality and soil properties by conducting a visual soil assessment (VSA). The activity involves digging up a 20 cm cube of soil to examine the soil ...
In this activity, students are introduced to cells. They learn that we are made up of cells. Students also learn how to use a microscope to observe onion cells. Rights: The University of Waikato ...
Myrtle rust is a serious biosecurity threat, and help is needed to monitor its spread. This citizen science project aims to gather information on the location, hosts and intensity of this fungal ...
Capture wild microbes and turn them into bread – for science! This is a project you could do with your students in the classroom or they can do at home. Microbes are found in every environment on ...
Help this global project to develop a faster test for antibiotic resistance by looking inside bacteria that have been treated with antibiotics. This will improve healthcare for patients with ...
Our bodies have a defence system against pathogens that make us sick. This defence system is made up of cells, tissues and organs that work together to protect us. It is known as the immune ...
Students investigate silage production and test a stream to see if run-off from silage is polluting it. Students then produce a pamphlet of their findings to educate the community. Purpose To ...
Modern antibiotic medicines came into use in the middle of the 20th century. They enabled doctors to treat serious – and sometimes fatal – bacterial infections like strep throat and pneumonia ...
Dr Selai Letica explains some of the causes of nitrous oxide emissions in agricultural soils and why it is important to limit them. Points of interest: Nitrous oxide (N2O) occurs naturally in the ...
Dr Ross Monaghan from AgResearch at Invermay in Otago explains his work in managing the risk of nitrogen loss to water systems through the use of nitrification inhibitors. Nitrification ...
Dr Selai Letica explains the process of denitrification. This is the phase of the nitrogen cycle where nitrate is converted back to atmospheric gaseous nitrogen (N2). Jargon alert: Dinitrogen is ...
