A Short Note On Classroom Observation

Post-Observation 2 Questions
What were the learning outcomes for the lesson? How did the learning outcomes meet the needs of individual students?
The students had to sketch the Lewis dot structures for several molecular compounds. They also visualized what it is meant by the statement “sharing of electrons.” Furthermore, they had to describe and visualize the meaning of covalent bonds.
The activity enabled all students, including the limited language proficient students, to visualize that even if some binary compounds have a combined total of 10 valence electrons, they can share enough electrons between each atom to satisfy the octet rule (8 valence electrons surrounding each atom). The students physically counted, moved, shared, and rearranged fruit loops around element symbols to model Lewis dot structures. The students thought of the fruit loops as valence electrons and arranged them in such ways that each atom appeared to have 8 valence electrons.
The entire activity was visually appealing to the students. As they transitioned to the computer labs, they observed that a covalent bond was composed of 2 valence electrons. They also noticed that some molecular compounds like N2 can form 3 covalent bonds because there are 6 valence electrons shared between each

Lewis Dot Structures,” shows that the student was able to correctly sketch all 15 Lewis dot structures. This specific student was actively sketching symbols on his white board and rearranging fruit loops as needed to make each symbol meet the octet rule. Each time his structures violated the octet rule, he tried different arrangements until he got the structure correctly modeled on his white board. Each time the student had the correct arrangement, he proceeded to sketch what he had modeled on his whiteboard. This was the process that most students followed: made a model with fruit loops that satisfied the octet rule, and then sketched the models into their
