Digestive System Interactive Notebook is an alternative method to simply labeling the digestive system in lesson. Suitable for KS3 and KS4.I have often found students often struggle to retain knowledge from simply sticking a diagram in their book and labeling it, so I created this as a more hands on approach to the human digestive system. There are 2 versions of the sheet for differentiation; one unlabeled, the other with the organs already labeled. The sheet is printed off and folded along the vertical fold line. The student then cuts along each of the horizontal lines to the fold line. They can then glue the sheet into their books and now have a flap based digestive system. The students then label the parts, find information on the organs and write this information under each of the relevant flaps. The final part is to colour in the different organs.
