An anteater is an animal that has long, sharp claws and a long, sticky tongue for finding and catching ants inside anthills. The picture below shows the South American giant anteater.
Picture shows an anteater that has long, sharp claws and a long, sticky tongue for finding and catching ants inside anthills.
  1. Identify a garden tool that can be used like the anteater’s claws.
  1. Describe how the tool you identified in part (a) and the anteater’s claws can be used in a similar way.
  1. Identify another animal that uses a body part in the same way as the tool you identified in part (a) is used. Explain your answer.
A student wants to catch different types of insects.
  1. Describe a method that could be used to catch insects that is similar to how an anteater uses its tongue to catch ants.

ScoreDescription
4 The response demonstrates a thorough understanding of how to compare natural systems with mechanical systems that are designed to serve similar purposes. The response correctly identifies a garden tool that can be used like the anteater’s claws, clearly describes how the tool and the anteater’s claws can be used in a similar way, and correctly identifies another animal that uses a body part in the same way that the tool is used. The response also clearly describes another method that could be used to catch insects.
4
3 The response demonstrates a general understanding of how to compare natural systems with mechanical systems that are designed to serve similar purposes.
2 The response demonstrates a limited understanding of how to compare natural systems with mechanical systems that are designed to serve similar purposes.
1 The response demonstrates a minimal understanding of how to compare natural systems with mechanical systems that are designed to serve similar purposes.
0 The response is incorrect or contains some correct work that is irrelevant to the skill or concept being measured.

Note: There are 2 sample student responses for Score Point 4.
