Toss the ball in the air and watch the colors magically flip! These fascinating balls transform back and forth between two colors. Amazing!!! Colors may vary. Chemistry teachers - for a great Activation Energy Demo, see the Pair of Switch Pitch Balls listed below. Pair of Switch Pitch Balls: Gently toss one in the air without spin and notice no change. Repeat with increasing energy until a change occurs. A beautiful lesson in activation energy! Point out the activated complex. Show the difference between translational and rotational energy. Use to demonstrate the activation energy needed for a reaction when two particles collide. Relate to the Arrhenius equation: k=Ae-Ea/RT. Demonstrate isomerization. Lesson plans (included with pair) offer suggestions on teaching chemistry from middle school to graduate p-chem courses. Includes two Switch Pitch balls with the same color combination and lesson plans.Hoberman Switch Pitch Ball
