The CDC needs your help. A deadly virus is sweeping the US. It is attacking parts of cells and killing its victims in a matter of hours. Make the right choices and save the world. Research the topics and proceed with caution. Click the icon to continue:

2. A virus is very simple. It consists of RNA and a protein shell
A virus is very simple. It consists of RNA and a protein shell. The virus will enter a person and use cells to manufacture more viruses. As the new virus fill up the cell the cells burst. This particular virus is only attacking parts of a cell. To understand how to stop it we must first begin to understand cells.

7. If cells are so small how can we see them?
Research the invention of the microscope. As you read about the microscope reflect on how technology is important to scientific discoveries.
Follow this link to research the microscope. Pay close attention to the events from
Who first used a microscope to view cells?
Robert Hooke
Ernst
Abbe
Antonie
Van
Leeuwenhoek

8. Correct!
Hooke first used a microscope to view cork cell. Even though the cells were from a dead part of wood he recognized that they were important to all living things. He thought they looked like the rooms in a monastery, so he called them “cells”. They may remind you of the cells in a jail! Click the link to continue.

9. Incorrect. You need to do careful research
Incorrect. You need to do careful research. We can’t afford these errors!

10. Incorrect. He did see living things, but not the first cells
Incorrect! He did see living things, but not the first cells. We cannot have too many set backs! Read more carefully!

11. Once cells were discovered…you won’t believe what happened next!
People started wondering why cells are significant. This curiosity led to many people interested in simply observing cells. People began to discover cells all around them, including in a drop of pond water.
Carefully observe the organisms in this drop of pond water. What conclusions can you make?
All living things are made of cells
Some living things are made of cells

12. The cell theory
The cell theory includes a statement of several facts about cells and the role they play in biology. Investigate the cell theory time line and write down the principle parts of the theory, who contributed to it and when the occurred.
Who would you want to interview to find out more about the cell theory?
Kolliker
Brown
Schwann

13. Characteristics of life

14. Hi
Guten Tag! My name is Albert.
And I helped to discover some
important things about cells. Click the biohazard icon to continue

15. What
What did you study? Hi
I was bon in Zurich and went to the university of Berlin. I mostly studied animals with out backbones , also called invertebrates.

16. What
What can you tell me about the cell theory? Hi
I helped to discover some new techniques for using microscopes. I also found out that sperm and eggs are actually cells!

17. What
Well ,thank you for your time and for the information. Hi
I am glad that you are investigating cells. If there is any other way I can help, Let me know.
