5. Slimy cells - Assessment
- Collect the ziplock bag cells and the keys. They can be displayed around the room for some time although students tend to like to take the models home and play with them.
- Provide other example conversion and ratio problems for students to solve.
- Revisit the characteristics of life list from the Is It Alive? activity. Revise the criteria as necessary to include that all living things are made of cells.
