Ck 12: Half Life
[Free Registration/Login may be required to access all resource tools.] In this module, students will explore the radioactive decay process in terms of balanced nuclear equations to discover the concept of half-life.
Texas Instruments
Texas Instruments: Half Life Lab
This activity explains how students use a CBL2 and TI-83 or TI-84 calculator to collect and calculate the half-life of a barium isotope. Students can use an isogenerator to milk out a meta stable isotope of Barium with a short half-life....
