Students learn to consider how people use scientific explanations to meet a need or solve a problem. They use the visual model, precise vocabulary and evidence to explain and apply the concept.
Learning routine: Observe → Model → Investigate → Record → Explain
Transfer the idea to a new example and justify the choice with evidence.
Apply the same relationship to the new context, then justify the answer using the labels and evidence shown.
Curriculum coverage and elaborations
The content description and elaborations below show the curriculum ideas taught in this unit. Items marked as teaching context support lesson planning.
Content description: consider how people use scientific explanations to meet a need or solve a problem
E1: recognising how First Nations Australians observe and describe developmental changes in plants and animals to make decisions about when to harvest certain resources (teaching context)
E2: exploring the history of manure and compost use in agriculture and how composting can help improve soil condition and plant growth
E3: investigating how understanding of life cycles of insect pests such as fruit flies led to effective control strategies
E4: investigating why salt, was so important to people’s diets, food preservation and medicine in ancient times that it was known as ‘white gold’
E5: exploring how science knowledge of heat transfer has helped people develop different ways to cook food, such as by boiling, frying or roasting
E6: investigating how engineers test the insulation properties of materials, and how this information is used to design food and beverage packaging, building insulation or clothing
Cultural safety for First Nations elaborations
Use reliable, community-approved sources and identify the specific Nation, People or community where the source does. Do not present diverse First Nations knowledges as one generic tradition. Follow local cultural and intellectual property protocols before reproducing cultural material or inviting community participation.
Guided learning activities
1. Model and notice
Use the visual model to identify need, then explain the important features.
Create an example using need, criterion and solution.

Revision Notes
Core idea: Students learn to consider how people use scientific explanations to meet a need or solve a problem. They use the visual model, precise vocabulary and evidence to explain and apply the concept.
Remember
Recognise need
Use criterion
Explain solution
Apply in a new context
Justify with evidence
