To celebrate World Oceans Day on 8th June 2012, we have created a special hands-on science lesson exploring the issue of ocean acidification. Get your students to replicate the work of Arctic scientists and gain an understanding of current science research in action!
Known as ‘the other CO2 problem,’ data on ocean acidification is showing that the increased rate of CO2 entering the atmosphere is also mirrored in the oceans, at a rate not seen for 300 million years. The effect of increased absorption of CO2 into the oceans is lowering the pH. Much scientific research is ongoing with regards to possible impacts.
The experiments in the lesson replicate the work of scientists on the Catlin Arctic Survey 2010-11, who camped on the frozen sea ice for two months and were examining what changes may occur to phytoplankton and zooplankton in the oceans’ current state, as well as if they were to become more acidic.
- A 60-min Science lesson, suitable for ages 11-14
- Includes three simple practical activities: what’s happening, the impact it may have on specific marine organisms, and the impact on the larger food web
