1 Cell Expo Cell Expo Cell models Episode 1: Cell models

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

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

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

5 Engage You have four tasks for this project: Build 3D 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 Cell models

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

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

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

9 Explore 9 Professor Jutharat Cell Expo Cell models Hello! Nice to meet you. I am a cell biologist. Do you know what a cell is?

10 Explore Cell Expo Cell models All living things are made of cells. 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?

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

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

13 Explore 13 Cell Expo Cell models SS1 It is challenging! Are you ready to use it now?

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

15 Explore 15 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?

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

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

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

19 Explain Cell Expo Cell models Nucleus Cytoplasm Cell Membrane

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

21 Elaborate Great! I think you are ready to make your cell models now. 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. 21 Cell Expo Cell models

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

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

24 Cell membrane Cytoplasm Cell Expo Cell models Red Blood Cell Explain

25 Nucleus Cytoplasm Cell membrane Cell Expo Cell models Explain Nerve Cell

26 Cytoplasm Nucleus Fat store Cell membrane 26 Cell Expo Cell models Explain Fat Cell

27 Soil particles Cell wall Vacuole Cytoplasm Cell Expo Cell models Explain Root Hair Cell

28 Muscle Cells Cytoplasm Nucleus Cell membrane 28 Cell Expo Cell models Explain
