Hello! I am teaching 4th grade Science and we are working on the body systems (digestive, respiratory, circulatory, and excretory.) I'm frustrated that we have so little time to spend on each one (not to mention the fact that it is taught in a language that the students are not proficient in, as an added difficulty.) I'm curious about how much time other teachers spend on each system, and if anyone has any effective demonstrations/experiments to illustrate key aspects. Thanks!
If they are learning in English, may I suggest you acquire FANDEX - The Human Body, as a reference that is visual, easy to use, and perfect for your age group? I bought mine on Ebay, less than $10. Kids love them.
When it is fun, the kids will spend more time and be more enthused. This is a resource that students can use on their own, it can be used in a fun way, to create teams that have to answer questions from the given information - my kids always love that. The same company that makes the Fandex cards also makes Brain Quest cards for varied grade levels, and if you get them cheap enough, they may have info you can use. http://www.rainbowresource.com/product/sku/005298/24876a25a2d0c41ba57e77a2 You may find more appropriate material at the link above. I don't know your age group, so just kind of flying blind. I like some of the things enough to purchase for my older kids with ED/BD problems. Anything visual, hands on, kinesthetic makes your life easier. Good luck
