Instruction For Gifted StudentsInstruction for Regular StudentEach student is to select a cell membrane model and read about it.Students are divided into groups and asked to make a chart with pictures of cell organelles.PROCEDURES:Activities for Gifted StudentsActivities for regular studentshttp://www.cellsalive.com/cells/cell_model.htm and Guide them to understand the cell and their functions hands-on.A video featuring the most important functions of a cell will be played to help students understand it better.

Each student must verbally present to the class the function of the organelle the student selected.Based on this, the instructor may ask questions:e.g. if the organelle is plastids:What will happen if plastids are absent in plants?The student will work in twos or threes and draw the organelle assigned to them. They must also write down the different structural features and functions of each organelle. For this they will be given a mere 10 minutes. The instructor leads the class and discusses the interaction between the organelles to perform certain functions.

Each group will read out the structure and functions of the organelle assigned to themPresent pictures of the differentiated body cells (blood, neural), and ask each student to write down their identification. The one to get most answers correct with the shortest span of time receives applause.Next the instructor discusses the interaction of the organelles to perform certain functions..Students are asked to write down names of different cells in the human body. (Nerve cells, blood cells etc).RESOURCES:Downloaded video explaining cellular function.

Colors and pencils for drawing. In case there is dearth of time, you may handout previously printed pictures of organelles instead of asking students to draw them.PRODUCTSGifted- Students will develop a thorough knowledge about cell membrane models and differences between each model. They will also be able to write down cellular functions of the body and functions of the organelles.Regular- Will be able to state functions of most organelles and describe different cells.ASSESSMENT:Gifted StudentsRegular StudentsThe student pair up, select a cell membrane model and make one using craft materials.
