I have just sent for a FREE science resource pack on Climate Change called Our Environment, from BP Education Service. I'm impressed with this teaching resource which is the latest addition to their website called Young Science Investigators Online Experiments.
In the pack there are four hands-on science experiments aimed at developing pupil's investigative skills, together with lesson plans, worksheets, stickers, stencils and a colourful A1 poster. The theme is Climate Change and what we can do about it. It is appropriate for Key Stage 2 children (P4-P7 in Scotland). Postage and packing is free too, so I think it's worth registering if you are in the UK.
Not only do you get this free pack, but if you register you will be able to access the great online animations which work really well on an interactive whiteboard and which have very positive reviews from teachers.
