Lesson Plan: Atomic Structure Unit Plan
The AACT high school classroom resource library has everything you need to put together a unit plan for your classroom: lessons, activities, labs, projects, videos, simulations, and animations. We constructed a unit plan using AACT resources that is designed to teach Atomic Structure to your students.

Isotopes, Atomic Mass, Subatomic Particles  Middle School, High School
Activity: Candy Isotopes & Atomic Mass
In this activity, students will learn about isotopes and be introduced to basic average atomic mass calculations. They will use simple numbers and M&M candies to model ratios that approximate real world atomic mass values on the periodic table.

Isotopes, Atomic Mass, Subatomic Particles  Middle School, High School
Activity: Simulation Activity: Isotopes & Calculating Average Atomic Mass
In this simulation, students first learn how the average atomic mass is determined through a tutorial based on the isotope abundance for Carbon. Students will then interact within a workspace where they will select the number of isotopes, the mass of each isotope as well as their abundancies in order to successfully build a mystery element. Finally they will use their choices to calculate the average atomic mass of the mystery element.

Isotopes, Atomic Mass, Subatomic Particles
Simulation: Isotopes & Calculating Average Atomic Mass
In the May 2017 simulation, students first learn how the average atomic mass is determined through a tutorial based on the isotope abundance for Carbon. Students will then interact within a workspace where they will select the number of isotopes, the mass of each isotope as well as their abundancies in order to successfully build a mystery element. Finally they will use their choices to calculate the average atomic mass of the mystery element.

Isotopes  High School
Lab: Isotopes Make Cents
In this lab, students use a sample of pennies to mimic how average atomic mass is calculated.

Isotopes  High School
Activity: Beanium Isotopes
In this activity, students will determine the average atomic mass of a sample of an imaginary element called Beanium.

Atoms, Subatomic Particles, Isotopes, Atomic Theory, History, Elements  Middle School, High School
Activity: Atomic Structure RAFT
In this activity, students choose from a number of activity options in order to best display their understanding of atomic structure. The RAFT model will be followed for this assignment, which means the students choose their assignment and may modify the assignment based on Role, Audience, Format, and Topic.
