Quick summary: In this activity students will model ‘natural selection’ by using different utensils to pick up food. Students participate in trials using different utensils, recording the results of their trials and reflecting on these results. Finally, students will be asked to create an cartoon, podcast or video to describe a real-life example of natural selection.
- Students will begin to understand the process of natural selection.
- Students will recognise the role of ‘selective agents’ in natural selection.

Australian Curriculum Mapping
Year 10 Science
- The theory of evolution by natural selection explains the diversity of living things and is supported by a range of scientific evidence (ACSSU185)
- Plan, select and use appropriate investigation methods, including field work and laboratory experimentation, to collect reliable data; assess risk and address ethical issues associated with these methods (ACSIS199)
- Evaluate conclusions, including identifying sources of uncertainty and possible alternative explanations, and describe specific ways to improve the quality of the data (ACSIS205)
Syllabus Outcomes: SC5-14LW.
General capabilities: Critical and creative thinking.
Cross-curriculum priority: Sustainability OI.2.
Relevant parts of Year 10 Science achievement standards: Students explain the processes that underpin heredity and evolution. Students independently design and improve appropriate methods of investigation, including field work and laboratory experimentation. When analysing data, selecting evidence and developing and justifying conclusions, they identify alternative explanations for findings and explain any sources of uncertainty.
Time required: 60 mins.
