Electrical Conductivity & Atomic Structure

Matter is composed of atoms containing positively charged nuclei and negatively charged electrons. Students will understand how atomic structure, electron mobility, and bonding determine whether a material conducts or resists electrical current.

Technology productivity tools

Use technology tools and resources for managing and communicating
personal/professional information (e.g., finances, schedules, addresses, purchases,
correspondence).

Investigate and apply expert systems, intelligent agents, and simulations in real-world
situations.

Understanding electrical conductivity is fundamental to modern electronics, energy transmission, materials science, and chemical analysis. Knowledge of conductive properties enables real-world applications in circuit design, industrial manufacturing, and environmental testing.

1. Formative Assessment: Pre-lab worksheet evaluating student understanding of atomic structure and charge interaction.
2. Performance Assessment: Lab investigation measuring the conductivity of various solid materials and liquid solutions using probe technology.
3. Summative Assessment: Post-lab analysis, data graphing, and written explanations connecting atomic structure to observed conductivity.

1. Pre-Lab Activity: Reviewing atomic components, electrical charge, and electron arrangement in conductive vs. insulating materials.
2. Conductivity Lab: Conducting hands-on testing of electrical conductivity across solid elements and aqueous solutions using digital sensors.
3. Post-Lab Analysis: Synthesizing lab findings, compiling graphical data, and presenting conclusions on electrical conductivity mechanisms.

tandard Title: CREATIVE AND CRITICAL THINKERS (3.4)

Students use creative thinking skills to generate new ideas, make the best decisions, recognize
and solve problems through reasoning, interpret symbolic data, and develop efficient techniques
for lifelong learning.
