For this lesson, Professor Wyrick and I were asked to be a guest speaker for a geology lesson. Within the two-hour time frame we had, students had an activity packet that they worked through, dissected a rock-cookie to see the minerals-materials that make up one, and went for a walk around the school grounds to identify types of rocks. The lecture included direct instruction, hands-on experiments, and collaborative work. Professor Wyrick and I co-taught the entire lesson, going back and forth with direct instruction and instructing student participation. The activity packet included concepts like the rock cycle, activities like a crossword puzzle, and a classification chart where students sorted rocks. All activities, worksheets, and hands-on experiences fit into where the students were at in their unit and supported their learning and application of concepts. 

Throughout this entire lecture, the students were constantly receiving information and applying it to the activities being performed. If students were unsure of an answer or did not understand a concept, Professor Wyrick and I would direct students to the concepts we covered and walk students through the process to get the answer they needed. This lecture was a constant assess and reassess for students to make sure they understood concepts and could find information if need be. The students themselves were constantly asking for clarifications and questions, which indicated that they were eager and interesting in what was going on, which showcases meeting this particular TPE.

Setting up this entire guest lecture was an entirely different process than lesson planning and teaching a lesson (even though there are many similarities) so by going through this process and what goes into planning and executing something like this, I feel more confident about putting together a lesson like this or asking a guest speaker to come to my classroom.  One thing for this particular lesson that I would add is for the actual hands-on experience to identify rocks to include a rock collection for the students to experience. Not only will students have the opportunity to identify, sort, and collect rocks, but they will have a mini collection as a souvenir that might inspire them to continue their collection.
