Standard
Goal
Monday
(Aligned to Texas Essential
Knowledge and Skills)
C.12B: describe
radioactive decay
process in terms of halflife of radioactive
isotopes
Students will describe
radioactive decay in terms of
a radioactive isotope’s “halflife”
Access Prior
Knowledge
New Information
“Think – Pair – Share” What is Carbon-14? How
does Carbon-14 dating
work? (10 min.) (7, 9)
Notes/Interactive Lecture –
Interactive ppt. presentation
– use grid/two-color visual
representation to teach halflife concept (2, 3, 6)
Review concept of isotope
(different neutron count)
Apply Knowledge
Kinesthetic Activity – Halflife of M&Ms (students will
simulate decay of atoms of
“radioactive” M&M isotope
to Skittles “daughter
isotope” atoms), plot curve
on graph paper (2, 6, 7)
