Today Dave began class by reviewing what the class had learned earlier in the week. He then went on to have them break up into groups before he told them what they would be doing today. He explained to them that they would be making a Power Point presentation tomorrow. The students were to complete an entire presentation including a model and some of the things that have gone over throughout the week. He continued by saying that each presentation would have to last about twenty minutes. The students worked hard on their projects all afternoon.
