Knows that when an element has atoms that differ in the number of neutrons, these atoms are called different isotopes of the element; although neutrons have little effect on how an atom interacts with others, they do affect the mass and stability of the nucleus.

Teaching Atomic Structure Using Cooperative Learning

Cooperative Learning is a teaching pedagogy that is great to use, but often challenging to implement. In a high school general chemistry classroom (non-honors level), the range of math abilities across the student population often means that some students catch on quickly to the algebra-based concepts. Other students struggle with very basic algebra. The beauty of using Cooperative Learning is that the science teacher can use the higher ability students as another resource for the students that need to have concepts reinforced.
