    Evidence shows that sea levels are rising – but how do scientists gather this evidence? After all, the sea level changes daily due to tides, waves and the weather. This article explains how scientists use tide gauges and satellites to look at data over long periods of time. It also explains some of the implications of sea level rise.

    The importance of evidence

    Climate change is one of the world’s big issues. To understand how the climate is changing and to understand how human actions have contributed, scientists gather and interpret data as evidence. The article provides a number of great images that show the impacts of climate change and sea level rise. There is also a diagram that maps the changes in sea level in New Zealand and provides students with the opportunity to develop the science capability ‘Interpret representations’.

    Teacher support material

    Check your school library for the article from the 2014 Level 3 Connected journal ‘Why is that?’, download it as a Google slide presentation or order it from the Ministry of Education. The slide presentation contains multimedia that supports the article, including a video on how tide gauges work.

    The teacher support material (TSM) can be downloaded from TKI. (Look for Word and PDF icons under the article abstract.) The material lists the key science and nature of science (NoS) ideas featured in the article. The notes provide explicit NoS links to sections of text. There are also four activities that support students to explore climate change issues and take action.
