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

What do houses represent?◦ Organs

What does the entire school represent?◦ An Organ System

Let’s jump back…

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
