Keep your cat inside

We know that cats are natural hunters, but what does the data tell us about cats and their prey – and how do we know if the data is reliable?

This article explores the tension that many of us have regarding cats. We know that they are natural predators, but many of our pets live in urban locations and away from our native endangered species – or do they? We hope that our furry companions keep the mice and rat populations down and potentially help native species by doing so. But is this true?

The role of evidence in science

The article also explores the role of scientific evidence, its relevance and reliability. It uses diagrams to present data from two New Zealand studies. The text includes questions that guide readers to consider what evidence means and whether it is reliable. The article supports the science capabilities ‘Gather and interpret data’ and ‘Interpret representations’.

The teacher support material (TSM) can be downloaded from Tāhūrangi as a PDF file. The materials list the key science and nature of science (NoS) ideas featured in the article. The notes provide explicit NoS links to sections of text.

The TSM offers six learning activities:

  • Digging deeper

  • Cats in our place

  • You be the judge

  • Critical thinking

  • Can we do it?

  • Building solutions

The activities support the ‘Understanding about science’, ‘Investigating in science’ and ‘Participating and contributing’ strands of Nature of Science.
