Engage

We would like your exhibition design company to develop an exhibition on cells for us.

Could you do this for me?

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.

Your first task!

Why do you think we want the 3D cell models?

7

Think further! Why do we want models of plant and animal cells?

Let me introduce you to one of our consultants, Professor Jutharat.

She will help you to understand the science behind the exhibition.

Hello! Nice to meet you. I am a cell biologist.

Do you know what a cell is?

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?

Right! We use a light microscope.

Do you know how to use one?

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.
