Finding a better milk is a week long scientific investigation based on the teachers experience with the Teacher Researcher in Partnership Program. Where they were placed with an Agriculture and Food researcher investigating milk alternatives.

Nature of the inquiry problem

The problem given to students will be based around researching milk alternatives. Their aim will be to experiment with Cow, Goat and Soy milk to establish which is the most easily digested.

Suitable year levels and subject areas

Year 8 - 10 Australian Curriculum

Curriculum links

Multi-cellular organisms contain systems of organs carrying out specialised functions that enable them to survive and reproduce (ACSSU150)

Chemical change involves substances reacting to form new substances (ACSSU225)

Additional content covered:

Collaboratively and individually plan and conduct a range of investigation types, including fieldwork and experiments, ensuring safety and ethical guidelines are followed  (ACSIS140)

Measure and control variables, select equipment appropriate to the task and collect data with accuracy (ACSIS141)

Summarise data, from students' own investigations and secondary sources, and use scientific understanding to identify relationships and draw conclusions based on evidence (ACSIS145)

Communicate ideas, findings and evidence-based solutions to problems using scientific language, and representations, using digital technologies as appropriate (ACSIS148)

Learning Objectives

Students will:

  • demonstrate how to use Biuret indicator to analyse protein content
  • practice how to dilute samples for analysis
  •  recall how enzymes work in protein digestion
  •  show how to take accurate measurements using pipettes
Student Learning Outcomes*

At the end of the inquiry students will:

  • understand that different milks are digested differently
  • understand how to conduct an experiment based on real-world contexts
  • be able to evaluate experiments to identify its validity and accuracy
  •  understand how studying food could support the health of future populations
Format

Work booklet, research (collaborative or individual)

Assessment outcomes

Informal, formative assessment is built into this week long investigation.

Information and communications technology (ICT)

Technology could be accessed to prepare student reports, graphs, and/or diagrams and to conduct further research.
