Our very survival depends on a reliable source of natural resources, including food. Primary industries use their knowledge of how physical conditions of the environment affect the growth and survival of living things to ensure good yields. However they are faced with new environmental challenges, such as rising salinity and changing weather patterns, which provide a highly relevant context in which to investigate how living things are affected by such changes.
The Rising salt unit is an ideal way to link science with literacy in the classroom. Through hands-on investigations, students explore how physical conditions of the environment, including methods of watering and salinity, affect the growth and survival of living things. With support, they plan and conduct an open investigation and design solutions to improve agricultural sustainability.
