Cell Expo Cell models Episode 1: Cell models 1

Objectives: 2 Cell models • To observe and compare the main components of plant and animal cells. Cell Expo • To observe and explain the shapes and characteristics of cells of unicellular and multi–cellular organisms.

Engage Could you do this for me? Cell Expo We would like your exhibition design company to develop an exhibition on cells for us. Cell models Mrs. Kannikar Wongthongsiri National Science Museum Officer (NSM). 3

Engage Cell Expo Have you visited NSM before? Cell models Let me take you on a tour 4

Engage You have four tasks for this project: • • 5 Cell models • Build 3 D models of plant and animal cells Write and design Information posters to show the functions of cell and their components. Design a ‘hands-on’ activities about the movement of substances into and out of cells. Write and design a brochure providing an overview of the exhibition. Cell Expo •

Engage Cell Expo Your first task! Why do you think we want the 3 D cell models? Cell models 6

Engage Cell Expo Think further! Why do we want models of plant and animal cells? Cell models 7

Engage 8 Cell models She will help you to understand the science behind the exhibition. Cell Expo Let me introduce you to one of our consultants, Professor Jutharat.

Explore Cell Expo Hello! Nice to meet you. I am a cell biologist. Cell models Do you know what a cell is? Professor Jutharat 99

Explore Cell Expo Cells are sometimes called the building blocks of life. Scientists say they are the fundamental units of living things. How big do you think cells are? 10 Cell models All living things are made of cells.

Explore Cell Expo Right! They are very small. What could we use to look at cells? (I’m giving you a clue here!) Cell models 11

Explore Right! We use a light microscope. Cell Expo Do you know how to use one? Cell models 12 11

Explore Cell Expo Cell models It is challenging! Are you ready to use it now? SS 1 13

Explore Look at these cells and draw what you can see. Cell Expo Now you know what cells are and how to use a microscope. Cell models 14

Explore Cell Expo Cell models What can you see inside the cells? Are all the cells the same? How do they differ? Are there any differences between the plant and animal cells? 15

Explain Cell Expo Cell models It is difficult to see the components inside the cells. I will show you what is inside the cell. 16

Explain Plant Cell Expo Compare what you could see with the two labeled diagrams. Cell models Could you see all of the structures shown in the diagrams? Animal Cell 17

Explain Chloroplast Cytoplasm Cell Expo Nucleus Cell models Cell Wall Vacuole Cell Membrane 18

Explain Nucleus Cell Expo Cell models Cell Membrane Cytoplasm 19

Explain Cell Expo How do plant and animal cells differ? Do they have all the same components? Cell models 20

Elaborate 21 Cell models I also have some materials for you. Select the things you want. You will need to search for further information - perhaps in a textbook or on the internet. Cell Expo Great! I think you are ready to make your cell models now.

Elaborate Cell Expo Please tell me how your models work. 22 Cell models Good job!

Elaborate I have many cell samples to show you. Can you tell me what components you can see? Cell Expo Cell models 23 23
