Hi H, Can you check the epa sites for rights. I can't find it. I think the reading currently are above our target audience and would like to swap them for the epa ones. Makes the content more about global warming. I will rework the activity a bit more
Sorry Tina - now i'm confused ;-) which are the epa sites? I've checked the rights for http://eo.ucar.edu/kids/green/cycles6.htm and it should be fine. Must provide citation details but ok for non-profit/educational purposes. Will try and track down which ones epa refers to...
