Cellular Life
Grade Level: 7th
Subject: Science
Time Frame: 8 weeks (August/September)
​
Essential Questions
​
- Where did bacteria come from? How long ago did bacteria begin?
- where do bacteria get their energy and how do they survive?
- why are all bacteria single-celled?
- how do bacteria adapt and evolve? Are bacteria more or less evolved than people?
- how do bacteria interact with each other? how do they interact with animals, including us?
- is there a connection between our cells and bacterial cells?
​
By the end of the unit, students will know:
​
- how cells were formed and evolved
- how mass is conserved
​
By the end of the unit, students will be able to:
​
- develop and use a model to describe how the total number of atoms does not change in a chemical reaction and thus mass is conserved
- develop and use a model to describe the function of a cell as a whole and ways the parts of cells contribute to the function
