assignment given by the teacher last discussion.

B. Establishing a purpose for the lesson

Teacher will show a video that explains the development of studying atoms.Students are expected to share their previous knowledge through KWL chart.

PICTURE ANALYSIS:Teacher will show a big picture of periodic table. Students are expected to analyze the picture.

Teacher will show a video of Nagazaki and Hiroshima Bombing.

Teacher will explain that alteration in the properties of elements can lead to total changes of its stability.

PICTURE ANALYSIS:Students will analyze pictures by means of describing the shape of an elements in S,P,D,F orbitals.

Teacher will guide the students that that shape plays an important role in the stability and property of an element.

C. Presenting examples/instances of the new lesson

Teacher will draw a flow chart showing the names of scientists who contributes to the development of atoms.

Teacher will give emphasis to the parts of periodic table.

Teacher will show problems related to isotopes.

Teacher will show how to get the isotope of an element

Teacher will show a video – 3D video showing the shapes of orbitals for deeper understanding.

D. Discussing new concepts and practicing new

concept.

E. Discussing new concepts and practicing new skills #2

Students will be group into 3 groups discussing the laws mentioned by the teacher.Group 1: Law of definite proportionGroup 2: Law of multiple proportionGroup 3: Law of conservation of mass

Students will answer exercises given by the teacher.

Students will be group into 5 groups completing the table asking for the atomic orbitals and quantum numbers of a given element.

F. Developing Mastery

Presentation of output.

Teacher will further discuss the topic.

Students are expected to

There will be game “Boys vs Girls” and they will answer the problems written on the board. The fastest group to answer all those questions correctly will be

Checking of their output.

Teacher will further discuss if there are clarifications.

the winner.

G. Finding practical applications of concepts and skills in daily living

Teacher will play a short video about the biography of Anton Lavoisier and students will find out the struggle of Lavoisier in proving his hypothesis.

Those problems mentioned in the discussion are situations from a real life setting.

Teacher will show a video depicting the importance of isotopes in different industries.

Teacher will show a video how orbitals and quantum model affects the stability of elements and how it is useful in different industries.

H. Making generalization and abstractions about the lesson

Students will make their own concept map differentiating the three laws mentioned in the discussion.

Students will make a KWL chart and summarize the lesson discuss for this day.

Students were asked to make a short narrative about the video showed by the teacher.

Students will get their partner and the first students will tell an element and the second will identify its atomic orbitals and VICE VERSA.

I. Evaluating learning

See page 60.Identification.

Students will answer exercises given by the teacher.

Checking of their activity.

See page 67

Complete the table.

See page 72-75

Complete the table.

There will be a recitation afterwards.

J. Additional activities for application for remediation

Boron has two stable isotopes with 79 and 81 amu, respectively. Naturally occurring boron contains 20% boron-10 and 80% boron-11. What is the average atomic mass of boron?
