I am planning earth science for 6th grade. We have been pretty lax with science, interest led, nature, documentaries. Considering this he has a good base knowledge(better than I thought) Science is my son's least favorite subject, he had no passion for it. I'm giving up trying to make it fun and get him excited. We just need to get it done. I want all planned out, do the next thing. Otherwise it will not get done. I will supplement with lots of documentaries because he has the best retention from them.
Thanks for the tips. I think I will go with the topic books. I actually have bacteria to plants I think I will pull it out and do a few lessons to check how it goes.
