Tuesday, 4/5/16- A Day

Learning Objective:

  • To interpret the information given in the periodic table to describe the arrangement of electrons on the energy levels around an atom

Learning Activities:

  1. Do Now– Copy down today’s homework assignment in your planner; Get out your science notebook and your Energy Levels Elements 1-20 activity handout; Looking at your periodic table on page 85, what element has 19 protons? How many electrons does that element have? How many neutrons?
  2. Advance Organizer- Periodic Table of Elements Brain POP animation
  3. Atom Models– Model how to arrange electrons within the energy levels for first atom model of each period. Students fill in the correct number of electrons in energy levels for the rest of the atom models in Energy Levels Elements 1-20 activity sheet. Tape Energy Levels Elements 1-20 activity handout as a flip page to page 89
  4. Comparison– Observe the chemical reaction of different elements and relate this to their location on the periodic table: sodium & potassium in water vs calcium in water
  5. Understanding Connections- Write an Understanding Connections statement about electrons & energy levels on a Post-It note and stick it to the Understanding Connections pages (p.80-81) of your science notebook.


Answer 2 questions on page 88.

  • 1. What pattern do you see in the periods (rows)?
  • 2. What pattern do you see in the groups (columns)?
