This PBL was a lot of fun. I chose just one 4th grade class to do it with because of all the details and the field trip at the end. The students literally loved this work. They did the research, but I gave guidance, especially in thinking of "older" music. I took two students to the Senior Living Center to interview the seniors on their musical favorites and the class went from there. They chose and designed 10 songs for performance. We took a field trip to the Senior Center and a Day-Care to culminate their research. They were SO excited. This piece details the steps including student instructions.It took 9 weeks from start to finish.
