Year 1, Term 2: Agriculture
Focus: Precision agriculture
Scope and sequence: Problem solving
explore how agricultural processes are used to grow plants
and raise animals.
Overview: Agriculture is another word for farming so it includes growing crops and well as raising livestock. This unit builds on prior knowledge from SILO F.3 'Living things' and leads into SILO 5.1 'Biochemistry'. The main focus is on introducing children to current farming practices and investigating how problem solving can be used to develop solutions for increased efficiency and yield. The concept of biosecurity is also introduced as another application of problem solving to reduce waste and disease.
Australian Curriculum (version 9.0)
"A student describes how agricultural processes are used to grow plants and raise animals for food, clothing and shelter." (ST2-5LW-T)
"Students learn to explore how plants and animals are grown for food, clothing and shelter." (AC9TDE2K03)
Introduction to the topic
Water and irrigation
The following screenshot is from a video (2:03) about irrigation. It can't be embedded on external websites so you will need to go to YouTube using this link (https://www.youtube.com/watch?v=amrCMakolKA). After watching this, see if you can recall the three main types of irrigation.
There are five key ingredients in good soil, namely:
The following video (6:23) specifies the first four of these ingredients and then adds the 'FBI' (i.e., fungus, bacteria and invertebrates) for the organisms.
The importance of valves
The direction of fluids is discussed in this video (5:23)
about valves, arteries and veins.
This video (2:48) from the UK shows how Salmon are farmed
This video (5:30) features Rachel Wilson who is an
Australian free-range egg farmer from WA.
The following video (4:55) tells the story of Panama TR4
in Queensland titled, Charlie goes bananas.
UNE Smart Farms
The following video (1:33) features Roman aqueducts and some of the engineering principles behind them.
Aqueduct construction activity.
The following video (2:12) shows how to make a desalination plant using the sun. It is more accurate to describe this as solar thermal energy as this experiment is based on evaporation and the light energy from the sun is not transformed into electrical current.
