Assessing the impact of sea level change in Google Earth

I’ve completed a new Google Earth based lesson which is part of a sequence of activities on surfing and climate change that will be announced later in the year. I’d like to get some feedback on this one though.

The case study is based on the Gold Coast of Queensland, Australia

The lesson gets students to create maps of sea level change which are then used to assess the likely impact on the region.

The lesson plan can be found at Juicy Geography: Modelling Sea Level Change
