Quick summary: Students model the effect of camouflage and feeding strategies on natural selection by conducting two experiments. In the first experiment they are asked to pick up coloured toothpicks off coloured paper using tweezers. In the second they are asked to use different implements to pick up dried beans.
- Students understand what is meant by the term ‘natural selection’.
- Students recognise what is meant by the term ‘selective agent’.
- Students understand that variations in camouflage or feeding strategies can influence natural selection.
