Short overview of Practice 2 Classroom teacher Paul Anderson gives a short overview of Practice 2.

NSTA Webinar This webinar uses Blackboard Collaborate when playing. It will not harm your computer. If your computer prompts you, you will need to "accept" to allow playback. This webinar was created before the final version of NGSS was available. However, the information presented is still pertinent and accurate. This webinar is excellent and I encourage you to view the whole thing. Please pay particular attention to the classroom examples that are given starting around 45 minutes into the webinar.

Ready, Set, Science!: Putting Research to Work in K-8 Science Classrooms Please read pages 76-83. A middle school classroom is described. The teacher is deepening student understanding through the use of models. Discussion and debate (practice 7) are also evident. Although this section of the book is focused on learning progressions, the use and evaluation of models provides us with a great illustration. Additionally, please read chapter 6.

Engineering connection. These Engineering is Elementary resources are lessons that teach the engineering design process in grades 1-5. Part of that process is creating models and refining the design. Please watch some of the classroom videos and look to see how the teacher guides the students in the process of creating models to work toward  a solution. The water purification examples, part 1 and part 2, could be used to elaborate on the water purification lesson example that was used in the NSTA webinar above. There is a social studies connection and an ELA literacy connection that can be seen in the 5th grade classroom video of lesson 1. Please pay attention to the engineering design process that is emphasized in the video resources, particularly in the classroom video segments of lesson 3 and 4.
