Summer PD Series: Differentiating Half-Life
Half-life is a core concept if you are teaching nuclear chemistry. It's also a relatively easy one to differentiate according to students' math backgrounds.
In this online session I will share with you three levels for approaching half-life problems: arithmetic, graphical, and exponential. I'll go over a suggested instructional sequence, practice problems and an inexpensive hands-on simulation application differentiated the same way as the problems. You can choose any combination of options to implement simultaneously.

Presenter bio:
Sue Klemmer earned her BA in Chemistry at Wesleyan University in 1975, and over the last few decades has spent several years in graduate school in several universities in several programs. She has taught science for forty years, thirty-two of them at Camden Hills Regional High School on the coast of Maine. In addition to chemistry (honors, college prep, tech prep, alternative, and adult ed) she has taught physics, earth-space science, and an integrated course for special needs freshmen. Sue currently teaches honors chem and C.P. physics. Her special interests are the use of history of chemistry to teach content and scientific methods, the use of concept mapping to both help students learn and to help teachers understand what students are thinking, and submicroscopic representations and modeling in chemistry. She has also recently become focused on metacognition. She serves as the Northern Division Chair of NEACT and facilitates the monthly ChemChats on ZOOM sponsored by NEACT.
