Kesler Science Station Lab – Cell Theory
If you have never used my Kesler Science Station Labs before please download the FREE Start-Up pack from my TPT store. It will provide you with all of the signage and best practices in order to run the station labs in your classroom.
The large directions cards included in this file are intended to be read by the leader of the group once the students get to the station. The smaller task cards can be read by another group member.
I prefer that each student do their own lab write-up (included at the end of this file), so that they may use it for reference at a later date. The answer key is provided at the end of the document.
Lastly, if any of the internet resources no longer work for some reason please let me know via email at [email protected]. I cannot guarantee that all resources will be available, but I tried to choose ones that have been around for many years.
Kesler Science Station Lab – Cell Theory –Teacher Directions
Explore It! – I will spend much of my time at this station making sure the students are not wasting time. You won’t need anything other than the cards provide with the explore it station.
Illustrate It! – Make sure to include colored pencils or crayons at this station.
Read It! – Print several different copies (I use 6) of the reading passage so that multiple students can read at different paces
Watch It! – The video is on YouTube and my Google drive. Use YouTube unless your school is blocked. The original link is https://www.youtube.com/watch?v=4OpBylwH9DUNote that both URL’s are case-sensitive.
Organize It! – The cards for this activity are attached near the end of this file. Print several sets and then just put them in the basket for kids to pull from. This is also a good one for later in the week to demonstrate mastery too! Students should be encouraged to do the Research and Explore station before attempting this one. I like to label the backs with set numbers because they will get mixed up.
Write It! – Students should be encouraged to do the Research and Explore station before attempting this one.
Research It! – The goo.gl link on the task card is case-sensitive. The original link ishttp://www.smithlifescience.com/CellTheory.htm
Assess It! – Students should be encouraged to do the Research and Explore station before attempting this one. If I grade anything I usually take a close look at the answers from this station.
It is recommended that you have completed at least two of the following stations before working at this station.-Read It!-Explore It!-Watch It!-Research It!
Answer each of the task card questions on the lab sheet in complete sentences.

1. Use the cards and classify each of them as either LIVING or NON-LIVING.

The cell theory was later developed by Theodor Schwann, Matthias Jakob Schlieden, and Rudolf Virchow. Its says:
Robert Hooke is first credited with discovering the cell when looking at thin slices of cork under an underpowered microscope. Anton van Leeuwenhoek also saw cells and organelles after using a much more powerful microscope.
All living things have cells. They are the basic unit of structure and for reproduction.
2. On your lab sheet write an explanation of how you determined whether something is living or not. What evidence did you use?
1. All living organisms are composed of one or more cells.
2. The cell is the most basic unit of life.3. All cells arise from pre-existing cells.
1. On your lab sheet copy the cell theory into the Explore It section.
2. List 2 items that have cells and 2 items without cells (do not use anything previous from the cards).
Each member of the group will draw a quick sketch on the lab sheet the shows they understand the concept that is being taught.
Use the colored pencils and markers that are provided.
The directions for the sketch are provided on the task card at the table.

Robert Hooke coined the term “cell”.
Leeuwenhoek worked with higher-powered microscopes to see many more details of the cell.
Schwann and Schleiden collaborated on the cell theory. The cell is the basic building block for life. All living things are made up of one or more cells.
Virchow says that all cells come from pre-existing cells.
