Standard:

CH1.d. Students know how to use the periodic table to determine the number of electrons                        available for bonding.

CH2. a. Students know atoms combine to form molecules by sharing electrons to form covalent bonds

CH2.b. Students know chemical bonds between atoms in molecules such as H2, CH4, NH3, CCH2, N2, CL 2 and many large biological molecules are covalent. 

CH2.e. Students know how to draw Lewis dot structures. 

Objective:  SWBA to build covalent bonds and predict the shapes of molecules by applying Lewis Dot structures and the VSEPR theory with 80% or more accuracy.

Activities: 1. Warm-up

2. DII strategy: Covalent bonding and Molecular shapes

3. Kinesthetic activity- Build three-dimensional models of the molecular shapes

4. KAGAN Strategy- Numbered Heads together

Warm-up:

1. Which statement best describes the density of an atom’s nucleus?

1. The nucleus occupies most of the atom’s volume but contains little of its mass.
2. The nucleus occupies very little of the atom’s volume and contains little of its mass.
3. The nucleus occupies most of the atom’s volume and contains most of its mass.
4. The nucleus occupies very little of the atom’s volume but contains most of its mass.

2. Draw the Covalent bond of H2
