3200-03 Students will understand structure and function of cells and
OBJECTIVE 3200-0301 Evaluate evidence to support cell theory.
Intended Learning Outcomes:
- 1c. Use reference sources to obtain information.
- 4a, b, c. Historical development of science, developments in technology,
contributions of scientists.
- 5b. Basic science facts.
- 6d. Construct a chart (timeline).
Reviewing the history of the development of the cell theory on the previous
- 1. Students will research historical events leading to the development
of the cell theory.
- Research should include contributions made by the following people/scientists
-Robert Hooke, Hans and Zacharias Janssen, Anton van Leeuwenhoek,
Matthias Schleiden, Theodor Schwann, Rudolph Virchow, etc. and dates
of their contributions.
- 2. Students will report on their findings by constructing a timeline
showing the chronology of the historical events leading to the development
of the cell theory.
Materials for each student or pair of students:
- Reference materials (texts, encyclopedias, Internet, teacher handout
- colored pencils or markers.
- Research the following people: List some of their contributions to
science and dates of these contributions.-
- Robert Hooke-
- Hans and Zacharias Janssen-
- Anton van Leeuwenhoek-
- Matthias Schleiden-
- Theodor Schwann-
- Rudolph Virchow.
- Draw a timeline showing the chronological order of these scientists
and their contributions.
- Label the timeline with dates of the above scientists' discoveries.
- The earliest date should be on the left of the timeline and the
most recent date on the right.
- Label each date with the corresponding scientist's name and contribution(s)
in an organized and legible manner.
- Be sure your spacing shows a reasonable approximation of the amount
of time elapsed between dates.
1. What theory did these scientists provide evidence for?
2. What instrument was necessary before the cell theory could be developed?
3. Which three scientists directly contributed evidence for the cell theory?
4. How did the earlier scientists and their contributions directly affect
the discoveries of later scientists (see #2)? For example, what had to
5. List the three parts of the cell theory.
