To increase understanding of how cosmic rays are related to antimatter


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 will give students an understanding of the nature of cosmic rays (in particular, how cosmic rays are related to antimatter). The lesson also includes a half-day hands-on activity that allows the students to detect cosmic ray particles in the classroom.
Upon the completion of this lesson, the student shall:
-Understand how antimatter is created by a natural process
-Realize that antimatter was first discovered in cosmic rays
-Be aware of the existence of two other types of particles: pions and muons
-Become familiar with the construction and use of a simple particle detector
