Earthlearningidea will use the opportunity of the International Year of Planet Earth (2008) to publish on the internet a new Earthlearningidea each week for use in classrooms that have few resources. The International Year of Planet Earth (IYPE) was proclaimed by the United Nations for 2008, with the activities extending from 2007-2009. IYPE has a scientific programme with an equal and parallel outreach programme, with the objective of enhancing the understanding about the Earth of the global population. The Earthlearningidea activities are aimed at teacher trainers (pre-service educators) of teachers in science, geography and Earth science, and interested teachers as well. Each activity, using minimal resources, provides the opportunity for interactive and engaging teaching that will not only develop knowledge and understanding of how the Earth works at individual, local and global scales, but will enhance the investigational and thinking skills of pupils. Internet discussion around each activity will be encouraged through a blog. Readers can join us via our website www.earthlearningidea.com through linking to "Blog-free subscription to ELI", by contributing to the global discussion, by offering expertise, and by providing support to this voluntary, fundless initiative.
