These educational posters can be used in conjunction with Ralph Pirozzo’s book The Thinking School (HB7658).


 The PSDR poster encourages students to go through a four-stage thinking process that involves:



  • 1. Predicting the outcome of an experiment


  • 2. Sharing their predictions with others


  • 3. Doing the experiment


  • 4. Reflecting on the outcome of the experiment
