Atomic Number Lesson Plan

Instructor: Julie Zundel

Julie has taught high school Zoology, Biology, Physical Science and Chem Tech. She has a Bachelor of Science in Biology and a Master of Education.

Learning about subatomic particles can be dull; however, this lesson plan allows students to learn all of the associated vocabulary in fun, interactive ways while also focusing on class- and team-building activities.

Learning Objectives

After this lesson, students will be able to:

  • Determine the number of protons, neutrons and electrons of an element by using the periodic table.
  • List the location, charge and names of subatomic particles in atoms.
  • Define the key vocabulary terms associated with this lesson.

Length

  • 100 minutes

Curriculum Standards

  • CCSS.ELA-LITERACY.RST.9-10.4

Determine the meaning of symbols, key terms, and other domain-specific words and phrases as they are used in a specific scientific or technical context relevant to grades 9-10 texts and topics.

  • CCSS.ELA-LITERACY.RST.9-10.5

Analyze the structure of the relationships among concepts in a text, including relationships among key terms (e.g., force, friction, reaction force, energy).

  • CCSS.ELA-LITERACY.RST.9-10.7

Translate quantitative or technical information expressed in words in a text into visual form (e.g., a table or chart) and translate information expressed visually or mathematically (e.g., in an equation) into words.

  • Sticky notes
  • Notecards numbered 1 through 12 (each notecard has a different number)
  • Notecards labeled with the first 12 element symbols on the periodic table (each notecard has a different element)
  • Notecards with the number of neutrons for the first 12 elements written on them (one number per notecard)
  • Periodic table, one per student
  • 24 notecards with the key vocabulary terms written on them (each term will be written twice or even more if greater than 24 students)
  • Access to the video lesson Atomic Number and Mass Number
  • Copies of the lesson quiz, one per student.
