Daily Lesson Plan(nucleus of an atom)

An Example of a Daily Lesson Plan using the 4-phase Teaching Model/Learning Cycle

 

Subject    : Physics

Class       : Form 5DPLI

Date        : 22 June 2009

Time        : 09.30 am – 10.10 pm (30 minutes)

No. of students:              36 students

Learning Area              :              Radioactivity

Learning Objective:              Understanding the nucleus of an atom

 

Learning Outcomes:              At the end of the lesson, a student is able to:

 

     A  Master content knowledge

1. Describe the composition of the nucleus of an atom in terms of protons and neutrons.
2. Define proton number (Z) and nucleon number (A)
3. Explain the term nuclide
4. Use the nuclide notation

 

B              Master Scientific Skills/TSTS

1. Able to classify and do comparison between proton, neutron and electron.
2. Work together in a group and discuss the composition of nucleus of an atom, nuclide, nuclide notation, and isotope and then, present them to whole class. (communication skill)

 

C              Demonstrate Scientific Attitudes and Noble Values

1. Actively participate in group discussion in order to come out with the true concept of an atom. Define proton number (Z) and nucleon number (A)
2. Appreciate the value of time discussing the important things briskly and being on task all the time.

               

 

Scientific Concepts:             

              The composition of nucleus of an atom:

1. Proton
2. Neutron

 

Materials, equipments and resource materials:

1. Mahjong Paper / Mini white board
2. Marker pen
3. Notes / PP slide

 

Consideration of Safety Precautions: None

 

Prior Knowledge:

Students have already learnt about nucleus of an atom in Chemistry subject in Form 4. This topic should be like a revision of what they have learnt before.

Phase	Content	Teaching and Learning Activities		Notes
		Teacher Activities	Student Activities
Introduction/Eliciting Ideas (5 minutes)	Composition of an atom is consists of proton and neutron	Ask student to list down of items that have a center and outside that made of different materials.	Students list down their answers.	Strategy/Technique: Whole class Q&A
Structuring/ Restructuring of Ideas (15 minutes)	Composition of the nucleus of an atom: neutron proton   Definition of proton number (Z) and nucleon number (A).	Ask four central guiding questions:   What is the composition of the nucleus of an atom?   What is the definition of proton number and nucleon number?   What do you understand about nuclide?   How to use the nuclide notation?     Divide class into 4 groups of 6 students.   Ask students to form a group, find the facts and the concepts and characteristics of an atom and present their findings in front of the class.   Guide students to make use of the definition of proton number (Z) and nucleon number (A) in order to define nuclide notation.	Students work in groups to find out the answers for central guiding questions.   Each groups should come out with concepts, model and can draw a simple diagram of an atom.   Students make conclusion and understand that proton number (Z) = number of protons in its nucleus and nucleon number (A) = total number of protons and neutrons in its nucleus.	Strategy/Technique: Co-operative learning (group discussion)                 An inquiry activity in groups.
Application of Ideas (5 minutes)	Find the number of protons and neutrons in a nucleus of a few elements using nuclide notation.	Show problems on slides	Students solve problems in groups	Strategy/Techniques Group discussion followed by group presentation   Resources: PP slides
Reflection/ Closure minutes)	1.The composition of nucleus of an atom: a. proton b. neutron   2. a) Proton number (Z) = number of protons.     b) Nucleon number (A) = total number of protons and neutrons.	Let students conclude by stating the main ideas and relating to students initial ideas Show summary of main ideas on slides   Give reading assignment on isotopes for next lesson.   Written problem solving using in exercise book.	Students conclude the lesson by verbally stating the main ideas and relating to their initial ideas	Strategy/Techniques: Whole class Q&A   Resources: PP slides
