MS Science Using The Atomic Mass and Creative Applications

JPII science teacher Nicole Schatzle's 8th grade science students where each given an element from the periodic table of elements and they had to use the atomic mass to determine neutrons, use the atomic number to determine protons and electrons. "They had to use that information to make 3D models of their assigned element," said Mrs. Schatzle, "showing where the nucleus is located and where their subatomic particles are located."

Benefits include:
Understanding Atomic Structure: 

  • Protons, Neutrons, and Electrons: By calculating the number of protons, neutrons, and electrons, students gain a solid understanding of the building blocks of atoms. Students learn how to use the atomic number and atomic mass to derive the composition of an element's atom.
  • Nucleus vs. Electron Cloud: Constructing a 3D model helps students visualize the nucleus, which contains protons and neutrons, and understand how electrons are arranged outside the nucleus in specific regions or orbits.

Applying Mathematical and Analytical Skills:

  • Critical Thinking: Determining the number of neutrons from the atomic mass requires students to subtract the atomic number from the atomic mass, reinforcing their mathematical and problem-solving abilities.
  • Real-Life Application: This task allows students to see how scientific data can be represented visually, strengthening their ability to interpret and apply abstract numbers and concepts in a tangible, real-world way.

Strengthening Spatial Reasoning and Creativity:

  • 3D Models: Constructing a physical model requires students to translate theoretical information into a spatial representation. This strengthens their spatial reasoning skills and helps them visualize atomic structure, which can be abstract when viewed on paper.
  • Creative Engagement: The creative aspect of designing models engages students more deeply in the material and encourages them to personalize their learning experience.

Solidifying Knowledge of the Periodic Table:

  • Element Properties: As students focus on a specific element, they are introduced to the diversity of the periodic table and how different elements vary in structure. This also reinforces their ability to navigate the periodic table and understand how atomic numbers and masses are organized.

Preparing for More Advanced Topics:

  • Future Learning: This exercise is foundational for more advanced studies in chemistry, including understanding chemical bonding, reactions, and molecular structure. By grasping atomic structure early on, students are set up for success in higher-level science courses.


According to Mrs. Schatzle, she hopes her students build a concrete understanding of atomic structure and subatomic particles and that the assignment merges scientific understanding with creative application, aiming to solidify abstract concepts in a memorable, hands-on way.. "Developing critical thinking and problem-solving skills through calculation and model-building is a major take-away," she explained. "As is experiencing the satisfaction of making connections between abstract numbers and visual, physical representations, engaging creatively with science, fostering a deeper interest in the subject."
