Purpose

To raise awareness of 14 and 15 year olds to the process of how energy is transformed into matter and antimatter

Information

This lesson plan is part of the Anti-Matter Teaching Module (see related documents).  
Duration of lesson:  approximately 30 minutes.  ( duration may vary depending on how it is used)
 
 
Care has been taken to ensure that the mathematical knowledge required for students to successfully complete these lesson plans harmonizes with that which is expected of students in the 9th and 10th forms, according to a representative sample of national curricula. For some of the more calculation-intensive lesson plans, teachers may find the Background Materials helpful. Teachers may also discover that the required calculations can provide an opportunity for training in the use of calculators and/or computer graphing programs.
In the related lesson plan "Operation Annihilate" (see related documents), the students learned that the annihilation of matter by antimatter produces energy. This lesson gives students a look at the reverse process: the transformation of energy into matter and antimatter.
Upon the completion of this lesson, the student shall:
-Be aware that energy and mass are interchangeable quantities (that they can be transformed into each other).
-Understand that when energy is converted to mass, it always does so by producing 50% matter particles and 50% antimatter particles.
-Be able to perform calculations involving the conversion of energy to mass using the formula E=mc2
