Levels of Organization
By Miss Musich
Organize – to put something in order◦ We organize to make something more
manageable.
◦ For example, the MWMS is organized! Students are the basic unit A group of students make up a grade (6th, 7th or 8th) A group of grades make up a house (6th + 7th + 8th = Red) A group of houses make up the whole school.
Why do we organize like this?
Why do we need to organize?
Cells are the smallest unit in the body◦ So small you need a microscope to see them!
Cells
Red Blood Cells Onion Cells
Organelles are like organs for cells!
Cells have organelles!
nucleus
cell membrane
cytoplasm
A group of cells make up…
Tissue!
Not that kind of tissue…
Bone tissue is a group of bone cells working together!
A group of tissues make up…
An organ!Try again!
A group of bone tissue makes up an organ like the femur seen here!Did you know the femur is the longest bone in the body?
A group of organs make up…
An organ system!
A group of organs (bones) make up the
skeletal system!
…to my example earlier.
What do MW students represent?◦ Cells
What do grades represent?◦ Tissue

Role-play!
Once you receive a strip of construction paper, fold it into four squares so it looks like this:
Then illustrate and label each box with the levels of organization starting from smallest to largest. Also, please write the definition of these structures on the back
Study Strip!
