Mayan+Studies

Ok, I am so new to this format, I am not really sure what I am doing! I'd really like to have a greater understanding of the 4th grade curriculum so that I can integrate my program into it a bit better. Sometimes I feel like I am "off" with what I am doing and with what you guys are doing in the classroom. Here's what I do: shore studies (to integrate with Shore Trip and Sea Creature reports), electricity (philadelphia), mold (which fits in with nothing, but is just plain fun and a great science process unit) and rainforst (Maya). It is pretty packed, but is one of my favorite grades curriculum-wise. Any suggestions for better integration? Moving units around perhaps? BTW, I love your ideas for the Philadelphia unit - can we somehow have the electricity unit fit in a biit better with it? Perhaps a bit of current electricity issues/topics? Michelle, what do you think? Folding in an environmental bent to this? Usage patterns in Philadelphia? Ways to conserve electricity? Alternate energy sources?
