Students to research on the internet the following Scientists:
1.
Hans and Zacharias Janssen - Microscope makers
2.
Robert Hooke - First to see a cell
3.
Anton Leeuwenhoek - Discoverer of microorganisms
4.
Matthias Schleiden - Looks at lots of plants and decides that all plants are made up of cells.
5.
Theodor Schwann - Looks at lots of animals and decides that all animals are made up of cells.
6.
Rudolf Virchow - sees yeast(?) dividing and decides that all cells come from pre-existing cells.
7.
August Weismann - applies the cell theory to evolutionary theory.
They make a powerpoint that has a picture of the scientist, the relevant dates and a picture of what they make, find out or see.
Use the information gained to create a timeline of the development of the cell theory as the last page on the powerpoint!
Questions you might ask:
1. What theory did these scientists provide evidence for?
*the cell theory
2. What instrument was necessary before the cell theory could be developed?
*The microscope
3. Which three scientists directly contributed evidence for the cell theory?
*Matthias Schleiden, Theodor Schwann, Rudolph Virchow

4. How did the earlier scientists and their contributions directly affect the discoveries of later scientists (see #2)? For example, what had to come first?
*Hans and Zacharias Janssen had to first develop the microscope before cells could be discovered. Robert Hooke then discovered empty, dead cork cells in tree bark. Anton van Leeuwenhoek discovered the existence of living cells and is sometimes given credit for the microscope.
5. List the three parts of the cell theory.
*All living things are made of cells.
*Cells are the basic units of structure and function in living things.
*Living cells come only from other living cell
