After the exploration the teacher, with the student's help, constructed the concept: "Used paper can be recycled to make new paper." The students then engaged in another activity which was a letter writing campaign using, the newly made paper, to encourage policy makers in their community to urge all citizens to recycle. Mrs. Smith evaluated her students based on the their ability to demonstrate to her how to make paper from recycled paper, and on the quality of the arguments the students used in their letters to local policy makers.

She had one magnet that she used to demonstrate how magnets can pick up objects.

She asked each child to circle which objects will be attracted to a magnet. The next day her science lesson was on plants.
E) Mr. Strong's lesson about rocks and minerals to his fifth grade students started with a lecture on what would happen to anyone if they were caught throwing any of the rocks in his classroom. After that lecture he called upon different students to read the pages from the textbook out loud. When the students came to an activity in the chapter Mr. Strong stopped and talked about what would happen if they were to do the activity. After his brief explanation he continued calling on students until they reached the end of the chapter. Mr. Strong then assigned the questions at the end of the chapter with a warning that all of the questions were to be completed by the end of class as the students were going to be tested on that information the next day.
