For the past few years we have been using Jeannie Fulbrights Apologia Science and we all love it! Right now we are using the Human Anatomy and Physiology elementary science book. We just finished working on cell structure so the kids made their cells out of jello and candy...what kid wouldn't like this book?? Here are some pictures of them making the cells and then eating them. Fun Stuff!!! Sorry about the yellow pictures, I took them with my cell phone and it wasn't the best light.
