To reinforce learning acquired from CERN Antimatter Lesson Plan "Living in the Anti-Material World"



This 'extension topic' 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 one possible solution to the problem introduced in the CERN Anti-Matter lesson plan "Living in the Anti-Material World" (see related documents) - how to tell the difference between matter and antimatter.
Upon the completion of this lesson, the student shall:
-Become aware of another example of the underlying symmetry between matter and antimatter.
-Become aware of another form of radioactive decay (electron emission) and of the concept of nuclear spin.
-Understand how the decay of Cobalt-60 and anti-Cobalt-60 differs
