Date : 15 May 2012Form : 4 ActivePeriod : 9.30 a.m – 10.30 a.mNumber of students : 35 studentsTheme : Learning Area : Movement of Substances Across The Plasma MembraneLearning Objectives : Synthesizing ideas on Movement Of Particles Across The Plasma Membrane

Learning Outcomes : Explain the needed of substances move into cell.1. Understanding the plasma membrane structure and function.2. Explain the different ways molecules pass into and out plasma membrane.

Prior knowledge : Students already know about:1. The type of molecules use in organisms.2. The structure of cell.3. The differences between animal and plants cell.

Objectives: At the end of the lesson, students should be able to:-A) Content knowledge.

1. Write the structure and function of plasma membrane while doing the activity.2 Explain the various ways of molecules across plasma membrane while doing the activity.

3. Explain the process of transport across membrane while doing the activity.B) Scientific skill.

1. Communicating using the diagram to describe the structure of plasma membrane, the function and process of transport across membrane.

C) Scientific attitudes and noble values.1. Cooperative in group activity.2. Being confidents while doing the group presentations in the class.

Resources: Lecturer maker, freemind.

Structuring lesson

Teacher wishes salam and good morning to the class.

Teacher brings plasma membrane models to the class.

Then, teacher explain to the students about the molecules embedded in plasma membrane and it function.

Teacher put the models in front of class.

After that, the teacher separated the membrane component of the model.

Teacher asks students to match the structure and state it function.

Teacher tells them about the property of biological membranes which allow some substances across it.

Teacher asks a few questions about student’s prior knowledge.

1. What are the made up of plasma membrane?

2. Give me the accepted hypothesis for membrane structure.

Students wish salam and good morning to the teacher too.

Students pay attention to the teacher.

Students give their opinion based on the observation.

Students give some idea on prior knowledge about the state of plasma membrane.

Students answer the

Cognitive :Recalling(level : knowledge).

Activity Reinforcement

Enrichment

Teacher asks a few questions to elicit student’s idea about the topic.

1. Why the plasma membrane is selectively permeable?

2. What is the important function of protein associated with plasma membrane?

Students are told what they going to learn today.

Teacher shows the lecturer maker notes and explains about the movement of particles of substances into and out of plasma membrane.

Teacher shows slide presentation and give an explanation based on those question:

1. What is the particles of substances that can pass through the membrane?2. How many transport protein

involve in movement?3. What transport protein will

transport?4. Is it different? Why?

question given.

Students pay attention to the teacher’s explanation and are allowed asking questions.

Empowering(10 minutes)

EnhancingStep 3

(5 minutes)

5. How can it become different?6. What is the effect of solution at different concentration?

Teacher shows an animation about the movement of particles for each transport system. Teacher gives explanation on each steps which involve movement across the plasma membrane.

Teacher tells students some situation on different solute concentration

Teacher asks student to answer question shown in the lecturer maker.

Teacher asks student to do the enrichment of understanding in the lecture maker activities provided.

Student answers the question and check the answer.

Student open the lecture maker and do the activities.

Closure(5 minutes)

Cognitive

Teacher use freemind to shows a mind map of today lesson’s.

Students takes note of the mind map in their notebook.
