10/2/12 and 10/3/12

Date: 10/2/12 and 10/3/12

Class: Physical Science

Periods: B2,3 and W1,3,4

Outcomes: Students will be able to describe the 3 parts of an atom and the current atomic model. Students will be able to determine elements based on the atomic numbers and how many neutrons are in specific isotopes of elements.

Standards: UCP:1-3,5; A.1,2; B.1-3; G.3

Student Needs: 

Assessment Plan: Have students draw a simple atom labeling where the 3 parts are located. Students will determine the number of neutrons in specific isotopes.

Lesson Outline: Review the 3 parts of the Kinetic Theory > Ask students to explain what they know about atoms > Draw a simple model of an atom and discuss > Ask students whether atoms have mass > Have students read Section 2 > Ask students what the main points of the section are > Model determining the element based on atomic number (# of protons) and taking mass#-atomic#=# of neutrons > Have students determine # of protons and neutrons for several element isotopes > Ticket to leave: have students write down how to determine the # of protons and neutrons for an element.

Review: Ask students what the 3 parts of the Kinetic Theory are.

Anticipatory Set/Opening: Quarks video, ask students what they know about atoms.

Key Points: Atoms are made of protons and neutrons in a nucleus and electrons flying around in an electron cloud around the nucleus. The atomic number tells you the number of protons and the mass number minus the atomic number is the number of neutrons.

Teaching Input: Give directions for reading and #protons/#neutrons assignment.

Modeling: Draw simple atomic model. Asking questions.

Checking for Understanding: Ask students to repeat directions. Ask 

Guided Practice/Monitoring: Protons/neutrons work.

Closure: Ticket to leave: explain how to find the #protons and the #neutrons.

Independent Practice: Read Ch. 16 Sec 3

Reflection:
