Procedure

1. Pre: Students will have completed diagrams of a plant and animal cell.
2. Do Now: Open with the following questions, allowing time for responses: Can you see a cell with your naked eye? What do you need to observe a cell? How long do you think it took to discover the cell? Cell parts? Different types of cells?
3. Go to "I Saw It First" using the SMART Board.
4. Have students write down the different scientists and their discoveries that led to the discovery of the cell while advancing the microscope in their notebooks.
5. Hand out a copy of the "Time Line Activity" to each student. Click onto site on the SMART Board. Read out loud while students follow along on their papers.
6. Have students complete the "Time Line Activity."
