Purpose

To introduce 14 and 15 year olds to what happens when matter meets 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.
 
This lesson gives the students an understanding of what happens when matter meets antimatter. Some simple calculations enable students to get a quantitative idea of how much energy is produced when matter and antimatter annihilate each other. It is meant to be used in tandem with the related lesson plan titled "Energy's Spawn."
 
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 energy is also quantized in particles called photons.
-Be able to perform calculations involving the conversion of mass to energy using the formula E=mc2.
-Understand that an enormous amount of energy can be obtained by the annihilation of matter with antimatter, and that the energy produced is in the form of gamma radiation.
